Business Details

The company's largest segment, manufacturing and selling transformers, reactors, battery chargers, current sensors, LED-related products, and other items. In addition to domestic manufacturing facilities, the segment has a supply structure spanning multiple global sites including Mexico, China, and Southeast Asia. Key customers include U.S. PDU/UPS equipment manufacturers for data centers, as well as air conditioner, power tool, and industrial machinery manufacturers. The segment's strengths lie in high-frequency, large-capacity, and high-voltage-resistant technologies, and it positions clean energy-related markets as a priority focus area.

Recent Overview

Sales rose 6.2% year on year to a record high, driven by AI-related demand, but profit growth was modest due to costs from the Chinese site reorganization.

In FY2026 (ending March 2026), sales in the Electronic Components Business were ¥81,549 million (up 6.2% year on year), and segment profit was ¥3,304 million (up 1.0% year on year), representing increased sales and profit. While robust demand for Large Transformers/Reactors (for Data Centers) used in PDU and UPS applications for U.S. data centers drove performance, the recording of expenses related to production transfer and personnel rationalization for the reorganization of the Chinese production site meant that the increase in segment profit was modest relative to the sales growth. In addition, as a subsequent event, the company resolved to transfer its equity in its Chinese subsidiary, Tamura Automotive Electronics (Foshan) Co., Ltd., to a domestic Chinese company by around the end of June 2026, concretizing its policy of consolidating production of automotive boost reactors in Japan.

Key Products

product
Large Transformers/Reactors (for Data Centers)

Robust demand continued for PDU and UPS applications in U.S. data centers, driven by expanding generative AI demand. This product group is the primary driver of the segment's performance.

product
Reactors for Air Conditioners

Stable demand has been maintained for the HVAC market, making this one of the segment's main product lines alongside data center-related products.

product
Battery Chargers (for Power Tools)

Stable demand from power tool manufacturers has continued, serving as a stable contributor to segment revenue.

product
Automotive Reactors

While regional disparities in EV adoption remain, demand has been maintained at a certain level due to progress in vehicle electrification. Following the transfer of equity in the Chinese production site (Tamura Automotive Electronics (Foshan) Co., Ltd.), the company plans to consolidate production in Japan.

product
Transformers/Reactors for Industrial Machinery

Continued cautious stance on capital investment among domestic and overseas manufacturers resulted in flat sales for FY2026 (ending March 2026).

product
Current Sensors/Gate Driver Modules

As next-generation power electronics-related products, this product group is being deployed toward clean energy-related markets.

Growth Drivers

  • Continued structural and sustained robust demand for Large Transformers/Reactors used in PDU/UPS applications for data centers, primarily in the U.S.
  • Mid- to long-term expansion of the AI server and data center-related market amid accelerating adoption of generative AI
  • Improved profitability following completion of the Chinese production site reorganization and strengthened supply structure through production consolidation at Japanese and Southeast Asian sites
  • Expanded sales of total solutions for data center-related products such as HVAC reactors and current sensors
  • Deployment of focus products for clean energy-related markets (power infrastructure, next-generation communications, mobility)
  • Expanded supply of automotive boost reactors for HEVs in Japan, the U.S., and ASEAN regions (following production consolidation)

Risks

  • Risk of deteriorating business environment due to changes in trade policy, including tariff measures by the U.S. administration
  • Increased costs and profit pressure during the transition period associated with the reorganization of the Chinese production site (production transfer, personnel rationalization, equity transfer)
  • Risk of prolonged sluggish demand for Transformers/Reactors for Industrial Machinery
  • Sluggish growth in automotive electrification-related demand due to stagnation in the EV market
  • Risk of a sharp decline in demand for Large Transformers/Reactors due to fluctuations in the data center investment cycle
  • Risk of impact on raw material procurement due to escalating tensions in the Middle East, among other factors
