Moulded inductors tolerate wide temperature range of -40 to +155ºC

September 25, 2013 // By Julien Happich
TT electronics has launched the HM72E and HA72E moulded inductor devices, using proprietary blends of alloy core materials optimised for high temperature stability, high dc bias capability, low core losses as well as minimising oxidation.

Featuring a rust-resistant over-moulded construction, the inductors are operational from -40 to +155ºC making them suitable for powertrain applications where environmental conditions are demanding. Both devices are targeted at designers who require a buck, boost or buck-boost inductor for voltage regulation at fast switching frequencies up to 3 MHz but also need to save space. Additionally, the HA72E series is qualified to AEC-Q200 certification for automotive applications. Further features of the range include DC bias current of up to 45A and inductance levels ranging from 0.10 uH to 33 uH at a maximum dimension of 6.8 x 7.3 x 3 mm.
