Panasonic, ETQP4M Wire-wound SMD Inductor with a Metal Composite Core, 33 μH ±20% 3.2A Idc

AEC-Q200. 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 Low profile Excellent inductance stability over a wide range of temperatures Highly efficient Excellent heat resistance High bias current. Product Application Information. With an AEC-Q200 qualification, the ETQP4M series is 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.
