Panasonic ETQ-P3M series power inductors

Panasonic has launched the new ETQ-P3M series of high reliability power inductors for automotive and harsh environment applications requiring high heat (up to 150°C including self-heating) and vibration resistance (up to 30G). Benefiting from a shielded construction, low profile (only 3mm maximum height), excellent inductance and temperature stability over a broad temperature range, as well as low audible (buzz) noise, the components are ideal to be designed into high frequency switching systems over 2MHz.

Features

• Reduce core loss in high frequency band (More than 2 MHz)
• High heat resistance : Operation up to 150 °C including self-heating
• Low profi le : 3 mm max. height
• SMD type
• 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 effi ciency : Low RDC of winding and low eddy-current loss of the core
• Shielded construction
• AEC-Q200 Automotive qualifi ed
• RoHS compliant

Applications

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