Panasonic ETQP-M series metal composite type power choke coils

Panasonic’s ETQ-PM Series Metal Composite Type Power Choke Coils are suited for filter, step-down and stepup circuits for DC/DC converters. They are AEC-Q200 Compliant offering reliability when exposed to high temperatures along with a high tolerance to vibration.

Features

• High heat resistance: Operation up to 150°C including self-heating
• High-reliability: High vibration resistance as result of newly developed integral construction; under severe reliability conditions of automotive and other strenuous applications
• High bias current: Excellent inductance stability using ferrous alloy magnetic material
• Temp. stability: Excellent inductance stability over broad temp. range
• Low audible (buzz) noise: New metal composite core technology
• High efficiency: Low DC resistance of winding and low eddy-current loss of the core
• Shielded construction
• AEC-Q200 compliant

Applications

• Noise filter for various drive circuitry requiring high temp. operation and peak current handling capability
• Boost-Converter, Buck-Converter DC/DC
