PREMO Presents Their New High Power Choke PQ20 for Automotive Market

PREMO presents their new range of power inductors based on the PQ20 format (23x25x19 mm), it is a high energy storage choke and filtered, specially designed for the automotive market. Using flat wire in the winding assures the maximum capability of power management with the minimum DC resistance (less than 1.6 mOhm). The choke has a wide range of inductances from 1.5 µH up to 33µH supporting handing up to 62A. The product is placed in a plastic base and their output wires are used as SMD pins. Two pines more are included to improve vibration tests.

The main characteristics of these chokes are as follows:

High current capability up to 62 Amp
Small SMD format
Low losses due to rectangular wire it use
Wide range of operating temperature (from -40ºC to 125ºC)
For soldering to improve the vibration test
According to AECQ-200C standard

Main applications are the following ones:

Battery control unit
DC/DC converter and inverter
Engine control unit (ECU)
Starter generator
Transmision control unit
Water pump

Also, it can be used as input/output filters in boost or buck converters, and differential filters, etc.

PREMO possesses more than 200 codes in their catalogue that it includes magnetically shielded and unshielded power inductor, PREMO designs and manufacture power inductor since more than 45 years, that trustworthy PREMO as supplier for applications in converters DC/DC, automotive, exchanged power systems, filters, etc.
