ETQP4M Series Low Profile Power Choke Coils ETQP4M choke coils from Panasonic are a low profile, compact solution. Constructed from metal composite core technology, ETQP4M choke coils are highly reliable and offer high heat resistance up to +155°C. 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. These power choke coils feature low audible (buzz) noise. Designed to be used in automotive applications, and harsh conditions, these power choke coils have high vibration resistance. Features Surface mount design
