Improved reliability and efficiency in automotive applications

TT Electronics has launched the HA65A range of surface mount power inductors for high frequency and high temperature applications.The inductors are designed to meet the requirements of the automotive market’s growing need for certified, high power inductors specifically for buck, boost or buck-boost power converter topologies for optimum voltage regulation at fast switching frequencies.

Optimised for high efficiency and ‘low parasitic’ performance using low-loss ferrite core material and a helical coil configuration, the HA65A series inductors are designed for high density switching power applications such as DC/DC converters, low pass ripple current filters and EMI filters.The inductors operate across a temperature range of -40 to 155°C, suiting them for operation in punishing automotive applications.

The HA65A’s low DC resistance figures and low core loss are claimed to deliver higher overall system efficiency.Their shielded design is said to improve system level EMI performance, and the inductors’ AEC-Q200 Rev D, Grade 1 automotive certification confirms their rugged design for all types of passenger vehicle system requirements

Typical applications for the HA65A series include automotive powertrain, hybrid electric vehicles, start-and-stop systems and electric power steering applications.
