September 27, 2006, Osaka, Japan－Panasonic Electronic Devices Co., Ltd. will soon release the in-vehicle power choke coil featuring the large current usage, the high reliability, and the compact size, which has the highest heat resistance (150) in this industry and vibration resistance (30G).
Product name Power choke coil (7 mm square size・8 mm square size)
Series name 7 mm square size: PCC-MO754M series
8 mm square size: PCC-MO854M series
Price Depending on quantities and specifications
Production start October 2006
Production capacity 300,000 pieces/month (at the initial stage of production start)
Recently in the automotive electrical equipment, ECUs (electronic control units) have been increasingly installed inside the engine room. Under these conditions, power choke coils used for DC-DC converter circuits for ECUs will be required to be compact as well as to have the heat resistance and the high-reliability properties standing the high-temperature inside the engine room. To meet the market demand, Panasonic Electronic Devices Co., Ltd. has succeeded in commercializing two kinds of the in-vehicle power choke coil (7 mm square size・8 mm square size) and will soon commence mass production.
[Features]
