Revenue (full year)¥593,201 million¥559,639 million↑
Segment profit (full year)¥41,831 million¥34,072 million↑
Segment profit margin (full year)7.1%6.1%↑

Business Details

The Passive Components segment consists of (1) Capacitors, comprising ceramic capacitors, aluminum electrolytic capacitors, and film capacitors; (2) Inductive Devices, comprising coils, ferrite cores, transformers, and similar products; and (3) Others within passive components, comprising RF Components, Piezoelectric Material Components & Circuit Protection Components. Major customers are in the industrial equipment, automotive, and ICT markets, and the segment positions the GX/DX domain (renewable energy, EVs, Beyond 5G, etc.) as a mid-to-long-term growth opportunity. In FY2026 (ending March 2026), revenue increased year on year across all product categories, and segment profit margin also improved.

Recent Overview

In FY2026 (ending March 2026), revenue increased 6.0% year on year and profit margin improved to 7.1%, led by the industrial equipment and automotive markets.

In FY2026 (ending March 2026), Passive Components segment revenue was ¥593,201 million (versus ¥559,639 million in the prior period, up 6.0% year on year), and segment profit was ¥41,831 million (versus ¥34,072 million in the prior period, up 22.8% year on year), with profit margin improving to 7.1% (from 6.1% in the prior period). Capacitors benefited from higher sales to the industrial equipment market, and Inductive Devices from higher sales to the automotive market. Meanwhile, other passive components declined 1.3% year on year due to lower sales to the automotive market. Sluggish BEV demand continued to weigh on demand for automotive-related components.

Business Details

This segment, comprising Energy Devices (Rechargeable Batteries) and Power Supplies, accounts for approximately 54.7% of consolidated revenue, making it TDK's core segment. It holds an overwhelming presence in small rechargeable batteries for smartphones, notebook PCs, and tablets, and also offers power supplies for industrial equipment and EV applications. In FY2026 (ending March 2026), higher sales to the ICT market were the main growth driver, and the segment recorded the largest revenue increase in absolute terms among all segments.

Recent Overview

Higher sales of rechargeable batteries to the ICT market drove a 16.5% year-on-year increase in revenue to ¥1,370,304 million.

In FY2026 (ending March 2026), the Energy Application Products segment saw higher sales of Energy Devices (Rechargeable Batteries) to the ICT market, with revenue increasing ¥193,805 million (+16.5%) year on year to ¥1,370,304 million. Meanwhile, segment profit rose to ¥246,682 million (+5.2% year on year), but profit margin declined from 19.9% to 18.0%. Continued sluggish BEV demand, resulting in component demand falling below initial expectations, appears to be one factor behind the decline in profit margin.
