TDK Corporation has expanded its TFM201612BLEA series (2.0 x 1.6 x 1.2 mm – L x W x H) of thin-film power inductors for automotive power circuits, now supporting higher currents up to 5.6 A. The two new components offer rated inductances of 0.33 µH and 0.47 µH.
As electric vehicles (EVs) and advanced driver-assistance systems (ADAS) continue to drive growth in automotive electronics, the demand for compact, high-efficiency components has increased.
Power supply circuits in these applications must minimize energy loss and operate reliably in limited spaces and high-temperature environments typical of ECUs.
Compared to the previous TFM-ALMA series with the same footprint and 0.47 µH inductance, the new component offers a 16% higher rated current (5.6 A) and 31% lower dc resistance (22 mΩ). These improvements support higher current handling and reduced losses within existing design constraints. The inductors are rated for operation up to +150° C, aligning with requirements for thermal reliability in automotive use.
TDK’s development approach combines proprietary materials and design methods tailored to meet the demands of EV power circuits. The company continues to broaden its portfolio by incorporating thin-film, wire-wound, and multilayer inductor technologies.
