Overview
Murata Manufacturing is a Tokyo-listed electronic-components leader. In Q1 FY2026 under Murata's company calendar, capacitors generated 56% of revenue, high-frequency devices and communications modules 17%, inductors and EMI filters 13%, batteries and power supplies 7%, functional devices 6%, and Other 1%. Revenue rose 20.7% to JPY 502.264 billion and operating profit rose 59.8% to JPY 98.454 billion, aided by data-center and mobility demand, higher utilization, and a weaker yen; product-price declines, higher fixed costs, and materials inflation remain counterweights. The strongest moat is integrated materials, manufacturing know-how, and scale in first-layer components: Murata estimates 40% global MLCC share, 50% automotive MLCC share, 60% RF-inductor share, and 40% EMI-filter share. RF-filter IP remains differentiated, but its strength is reduced to 3 because Murata now estimates 40% SAW share, fully impaired JPY 43.8 billion of Resonant goodwill, and cited stronger Chinese competition and delayed high-frequency adoption. Batteries, functional devices, and Other have no verified moat. At June 30, Murata had 1,820,289,278 shares outstanding excluding treasury shares; the LEI still identifies the active entity but its GLEIF registration is lapsed. The sole current listing remains TSE Prime code 6981.

Moat Claims
Capacitors (primarily MLCC)
Multilayer ceramic capacitors (MLCC) and related capacitors
Revenue share is based on Murata's Q1 FY2026 company-calendar product-category breakdown (JPY 282.508B / JPY 502.264B revenue for the quarter ended June 30, 2026). Capacitor revenue rose 30.0% year on year, led by MLCC demand for data centers and mobility, while management still reported lower component selling prices.
Capex Knowhow Scale
Supply
Capex Knowhow Scale
Strength
Durability
Confidence
Evidence
High-end MLCC leadership is reinforced by integrated materials-to-product manufacturing, miniaturization and reliability know-how, the industry's largest company-reported supply capacity, and a 40% company-estimated global share. The advantage is strongest in demanding automotive and data-center grades; standard MLCCs remain exposed to price declines and rival capacity.
Capex Knowhow Scale moat: definition, examples, and stocks
Erosion risks
- Industry overcapacity leading to price wars
- Fast catch-up by major rivals (process tech and capacity)
- Geopolitical and supply-chain disruptions
Leading indicators
- Capex pace vs peers
- Utilization rates and lead times
- Gross margin trend in components
Counterarguments
- Other mega-suppliers can fund comparable capex (e.g., Samsung Electro-Mechanics, TDK)
- A meaningful portion of MLCC demand is commoditized and price-elastic
Inductors and EMI Filters
Inductors and electromagnetic interference (EMI) suppression components
Revenue share is based on Murata's Q1 FY2026 company-calendar product-category breakdown (JPY 64.254B / JPY 502.264B revenue for the quarter ended June 30, 2026). Revenue rose 22.4% as EMI filters grew in mobility and data centers and inductors grew in smartphones and mobility.

Strength
Durability
Confidence
Evidence
Murata groups inductors and EMI filters with capacitors as first-layer component businesses built on materials, manufacturing, supply, and cost capabilities. Company-estimated shares of 60% in RF inductors and 40% in EMI filters indicate meaningful scale, but the combined category spans less differentiated products and capable rivals can multi-source or catch up.
Capex Knowhow Scale moat: definition, examples, and stocks
Erosion risks
- TDK, Taiyo Yuden, Yageo, and other rivals expand comparable capacity or performance
- Customer multi-sourcing and price declines overwhelm scale economics
- Materials inflation or utilization declines compress component margins
Leading indicators
- Inductors and EMI-filter revenue growth
- Components operating margin and utilization
- Company-estimated RF-inductor and EMI-filter share
Counterarguments
- Reported shares are Murata estimates, not independently audited market measurements
- The category combines specialized RF parts with more price-sensitive products
High-Frequency Devices and Communications Modules
RF filters and front-end components (e.g., SAW) and communications/connectivity modules
Revenue share is based on Murata's Q1 FY2026 company-calendar product-category breakdown (JPY 86.138B / JPY 502.264B revenue for the quarter ended June 30, 2026). Revenue rose 5.0% year on year but fell 4.2% sequentially as high-frequency modules declined for smartphones and PCs; the broader Devices and Modules segment posted a JPY 12.9B operating loss.
IP Choke Point
Legal
IP Choke Point
Strength
Durability
Confidence
Evidence
Murata combines SAW-filter process, manufacturing, and supply scale with proprietary I.H.P.-SAW and acquired XBAR technology. This remains a differentiated RF capability, but the company-estimated SAW share fell to 40% in the 2024 value report, the entire Resonant goodwill was impaired in FY2025, and China-based competition and delayed high-frequency adoption weaken durability.
IP Choke Point moat: definition, examples, and stocks
Erosion risks
- Technology substitution (e.g., different filter architectures)
- Customer vertical integration or tighter co-design with competitors
- Regulatory/export restrictions affecting RF supply chains
Leading indicators
- RF design win announcements and teardown share
- Performance claims (loss, bandwidth) vs peers
- R&D cadence and patent activity (where observable)
Counterarguments
- RF content is highly contested; large semiconductor peers also have deep IP and scale
- Smartphone OEM concentration can compress supplier margins regardless of IP
Batteries and Power Supply
Small rechargeable batteries and compact power supply modules for electronics
Revenue share is based on Murata's Q1 FY2026 company-calendar product-category breakdown (JPY 34.782B / JPY 502.264B revenue for the quarter ended June 30, 2026). Revenue fell 2.7% year on year and 13.5% sequentially; data-center power modules and batteries grew, but power-tool batteries declined and the micro-primary-battery transfer reduced revenue. Scale and reliability have not produced segment-level durable pricing or switching evidence.
Functional Devices (including sensors)
Sensors and other functional devices for electronics (consumer, automotive, industrial)
Revenue share is based on Murata's Q1 FY2026 company-calendar product-category breakdown (JPY 30.508B / JPY 502.264B revenue for the quarter ended June 30, 2026). Sensors and actuators drove 23.0% year-on-year growth, but the heterogeneous bucket and strong sensor/timing-device rivals leave no verified segment-level moat.
Other
Other / residual businesses (reported as 'Others')
Revenue share is the rounding residual from Murata's Q1 FY2026 company-calendar product-category breakdown (reported Others revenue of JPY 4.074B / JPY 502.264B for the quarter ended June 30, 2026). The bucket is immaterial and heterogeneous, with no verified moat.
Evidence
the largest supply capacity in the industry
Murata also identifies integrated manufacturing from materials to finished products, miniaturization, reliability, and high quality as capacitor-business strengths.
gains in capacity utilization from higher production output
The components segment reached a 32.5% Q1 operating margin while absorbing lower product prices and higher material costs, consistent with meaningful scale economics.
Murata's share of the MLCC market is 40% ... 50% in the automotive market.
Direct share statement used as reported market share anchor.
technological capabilities, supply capabilities, cost competitiveness, and manufacturing capabilities
Murata identifies capacitors and inductors/EMI filters as core first-layer businesses supported by accumulated manufacturing and supply capabilities.
Resonant's proprietary XBAR technology achieves high attenuation with low loss
Supports an IP/process moat in high-frequency filtering where proprietary architectures and process tech matter.
