Power choke coil is highly vibration acceleration resistant

vibration-resistant choke coil
To integrate ECUs within or near the combustion engine, Panasonic developed the power choke coil for automotive use. The component features high vibration resistance; therefore, developers do not need to provide further anti-vibration reinforcement.

To achieve a compact and resilient solution the number of ECUs that are mounted within the engine itself is increasing. As a consequence the components of these ECUs require a high-temperature rating, support large current and have to sustain severe vibration conditions.

Especially for these requirements Panasonic Industry introduces a new Power Choke Coil with high resistance to heat and vibration in addition to the support for large current. Thanks to the use of ferrous alloy magnetic material, the new ETQP5M2R5YSK provides high inductance stability even at high bias current input and over a broad temperature range up to 150°C.

The product is AEC-Q200 qualified and features a low audible buzz noise. With its resistivity of 50 G or higher vibration acceleration it is perfect for automotive use in ECUs placed in the engine itself and mechanical-electrical-integrated ECUs. Also it is suitable as noise filter for various drive circuitry which require high temperature operation and peak current handling capabilities. Similarly Boost-Converter and Buck-Converter DC/DC applications are a suitable operation purpose.
