Panasonic Industry Europe introduces a new High Vibration Acceleration-resistant Power Choke Coil

Panasonic Industry Europe introduces a new High Vibration Acceleration-resistant Power Choke Coil

To integrate ECUs within the engine Panasonic developed the new ETQP5M2R5YSK power choke coil for automotive use. Thanks to the high vibration resistance no anti-vibration reinforcement is needed and therefore streamlines the production process

In an ever growing market for environmentally friendly and energy efficient cars the electrification of the automotive sector is progressing. More and more electric motors and therefore Electric Control Units (ECUs) are being integrated into vehicles to improve efficiency and comfort. 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 an excellent inductance stability even at high bias current input and over a broad temperature range up to 150°C. The new Power Choke Coil is AEC-Q200 qualified and features a low audible buzz noise. With its resistivity of 50 G or higher vibration acceleration it is the perfect application 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.
