Tomita Electronics

What Tomita Electronics does

Tomita Electric Co., Ltd. (トミタ電機株式会社, ticker 6898) is a Japanese specialty manufacturer of soft ferrite products, founded as a private company in 1952 and restructured as a public limited company in 1960. The company produces soft ferrite cores in both Mn-Zn and Ni-Zn chemistries, along with custom coils and transformers built around those cores, for applications including switching power supply transformers, telecommunications transformers, EMI/noise filters, DC/DC converters, and electric and hybrid vehicle power components. Manufacturing is concentrated at the Tottori, Japan headquarters and plant (45 employees) and at wholly-owned Zhuhai Tomita Electronics Ltd. in Guangdong, China (400 employees on a 33,500 m² site), with sales offices in Tokyo, Osaka, Hong Kong (Tomita Ferrite Ltd.), and the Netherlands. The company holds ISO9001, ISO14001, and IATF16949 certifications and is listed on the Tokyo Stock Exchange Standard Market.

The company's core technology is a portfolio of proprietary Mn-Zn ferrite materials developed in-house, including the 2N2, 2N4, 2N6, 2N7, 2N8, 2N9, 2H1T, and 2H2C grades, marketed against quantified performance targets — 35% lower power loss than the conventional 2G8 baseline at 100°C for 2N2, a 21% power-loss reduction and 5% saturation-flux-density gain for 2N6, and a 30% permeability uplift at 100kHz for 2H2C, among others. These materials are offered across an extensive core-shape catalog (EE, EI, EER, EFD, EPC, EP, PC, PP, RM, R, RA, RIB, RI beads, TR, TRH, RIH, SSC, TRS, TRSD, UU, UI, JPN, TMEC) and are applied to customer-specific coil and transformer designs. The company self-describes its underlying production system as 'monopolistic' and built on more than 70 years of specialization.

Tomita operates a direct B2B sales model with no public pricing: custom ferrite cores and coil-transformers are quoted per customer specification through the Japanese sales offices, Hong Kong, and the Netherlands. Revenue is generated through hardware sales of these components to manufacturers of consumer electronics (TVs, PCs), industrial equipment (inverter lighting, control equipment), telecommunications hardware, and automotive electronics (EV/HV power transformers and DC/DC converters). Revenue figures are not publicly disclosed; the company filed IR materials on the Tokyo Stock Exchange for the fiscal year ending January 2026. The discontinued piezoelectric ceramics line was wound down in July 2021, refocusing the business on ferrite materials and applied products. Leadership transitioned in March 2025, with Yoichiro Kamitani assuming the presidency following the retirement of Tetsuro Kamitani.

Core offering

Tomita Electric Co., Ltd. manufactures and sells soft ferrite cores (both Mn-Zn and Ni-Zn types) and custom coil-transformers built from those proprietary cores. The company produces a broad portfolio of standardized core shapes (EE, EI, EER, EFD, EPC, PC, PP, RM, R, RI, TR, UU, UI families, etc.) plus application-engineered coils/transformers for switching power supplies, EMI/noise filters, telecommunications transformers, and DC/DC converters serving consumer electronics, industrial equipment, and automotive electronics customers.

Product overview

Tomita Electronics (トミタ電機株式会社) is a specialist manufacturer of soft ferrite products, offering two core product lines: Ferrite Cores and Coils & Transformers. The Ferrite Cores product line includes multiple core types (EE, EI, EFD, EPC, EP, PC, PP, R, RA, RIB, RI Beads, RM, TR, TRH, RIH, SSC, TRS, TRSD, UU, UI, and EER types) available in both Mn-Zn and Ni-Zn materials, with specialized materials including 2N2, 2N4, 2N6, 2N7, 2N8, 2N9, 2H1T, and 2H2C for various temperature, frequency, and power loss requirements. The Coils & Transformers product line offers custom and mass-produced soft ferrite applied products in various type configurations for power supply, industrial, and automotive applications. These products work together as essential magnetic components in electronic equipment, with ferrite cores serving as the base magnetic material and coils/transformers being applied products that utilize these cores for specific circuit applications in televisions, computers, automotive electronics, and industrial equipment.
