Panasonic's ETQPDH series of choke coils are high-powered SMD inductors for automotive applications. The 14.7x13.2x13.1mm small size SMD package has been developed with Panasonic's original metal powder technology which has five patents pending.
High performance is guaranteed by using a metal powder (dust) core. High bias current and excellent inductance stability are achieved by using ferrous alloy magnetic material. ETQPDH series inductors use a unique resin mold structure and a long terminal which is cramped into the resin molded body. This special structure provides high vibration resistance up to 30G and avoids solder joint cracking.
