Growth in demand for high-temperature automotive and industrial circuitry has sparked Sumida to greatly expand its lineup of AEC-Q200 qualified SMD inductors. In early 2019, Sumida introduced the CDRH50D28B/T150 Series of high temperature shielded drum and ring core inductors, for a range of automotive applications. Five additional package sizes have now been added to the […]
PSMA/PELS sponsor pre-APEC power magnetics at high-frequency workshop
The Power Sources Manufacturers Association (PSMA) and the IEEE Power Electronics Society (IEEE PELS) are jointly sponsoring the fifth high-frequency magnetics workshop, “Power Magnetics @ High Frequency,” on Saturday, March 14, 2020. The workshop will be conducted on the day before and in the same venue as APEC 2020 at the Ernest N. Morial Convention […]
What do molded power inductors bring to high efficiency, compact designs?
Modern hardware applications trend towards compact designs that are power efficient. Passive devices don’t get as much attention as a microcontroller’s many sleep and shutdown states. However, every drop of available efficiency adds up and can make a difference. It’s possible to improve power efficiency with the right inductor. Power inductors are a necessary component […]
High-temp/high-current power inductors for LED headlights
TDK has expanded its lineup of metal core power inductors with the new SPM-VT series that is designed especially for the high thermal and current demands of automotive LED headlights. These wire-wound power inductors feature both a broad operating temperature range from -55 °C up to +155 °C and high rated currents from 4.7 A […]
Small footprint surface-mount inductors cover wide temperature range for power-dense apps
TT Electronics announced two new surface-mount device (SMD) power inductors: the HM66M series for use in high frequency power conversion systems and EMI filter applications, and the HM78M series for use in high density and high frequency DC/DC converter applications. The TT Electronics HM66M series power inductors are designed for the complex industrial and telecommunications markets. The HM66M is […]
How new inductor cores meet demands for smaller, quieter, and more reliable power
by Patrik Kalbermatten, KEMET Engineered composite cores have enabled inductor manufacturers to pack high inductance into a small volume. New FlakeComposite technology takes core performance to the next level, and adds extra mechanical resilience to enable new types of low-profile devices. Power inductors are crucial devices for managing the flow of energy in switching converters, […]
HIgh-current power inductors target automotive apps
Power management company Eaton today launched its automotive-grade HCM1AV2 product line of high current power inductors designed for the transportation market to address increased power conversion and filtering requirements. The HCM1AV2 is tested beyond AEC-Q200 Grade 1 requirements for added reliability and confidence desired by most automotive engineers. The robust molded construction makes HCM1AV2 ideal for high […]
Tiny shielded power inductors are AEC-Q200 Grade 1 qualified
Coilcraft’s new XAL7050 Series of high-temperature power inductors is available with inductance values from 22 to 47 µH and current ratings as high as 5.5 Amps, with low DCR for greater efficiency. For lower inductance values, Coilcraft offers a lower-profile companion, the XAL7030, with an identical footprint and inductance range of 0.16 to 10 µH. The XAL7050 […]
Molded power inductors feature wide inductance range up to 8.2 µH
Coilcraft’s XGL4020 Series of high-performance, molded power inductors feature the industry’s lowest DC losses and extremely low AC losses for a wide range of DC-DC converters (from hundreds kHz up to 5+ MHz). Additional performance improvements include a wider range of inductance values and improved Irms current ratings. The XGL4020 is available in twelve inductance […]
Thin-film power inductors boast rated inductance of 1.0 µH
TDK Corporation announces the development of a miniaturized thin-film power inductor in an IEC 2012 case size that can handle higher currents compared to conventional products. The low-profile TFM201208ALD power inductor measures in at 2.0 x 1.25 x 0.8 mm and is available with a rated inductance of 1.0 µH. Thanks to its reduced DC […]
