ETQP3M Series Low Profile Power Choke CoilsETQP3M choke coils from Panasonic are a low profile, compact solution. The use of ferrous alloy magnetic material ensures high bias current while low RDC of winding and low eddy-current loss of the cores enables high efficiency. Constructed from metal composite core technology, ETQP3M choke coils are highly reliable and offer high heat resistance up to +155°C. Designed to be used in automotive applications, and harsh conditions, these power choke coils have high vibration resistance. These power choke coils feature low audible (buzz) noise.FeaturesExcellent inductance stability over a wide temperature rangeHighly efficientExcellent heat resistanceHigh bias currentSurface mount designLow profileProduct Application InformationWith an AEC-Q200 qualification, ETQP3M choke coils are suitable for use in automotive applications. These choke coils are recommended as noise filters for drive circuitry that required peak current handling capability and high temperature operations. Other suitable applications include DC/DC buck converters and boost converters.Panasonic Non Standard SMT Inductors (Chokes)
