Wirewound Ceramic Case Resistors for Motor Controls in Automobiles


TT Electronics’ Wirewound SQP and WP- Series were successfully utilized in the motors used for controlling windows, seats, mirrors and wipers in automobiles. These applications required “load dump” resistors to prevent damaging high voltage transients. Our SQP and WP-S Series parts can be free standing or integrated into control circuitry. The customer chose to work with us because we were the only supplier able to offer a 50ppm TCR.
