High pulse withstanding chip resistor ideal for protection and discharge applications
HPWC is TT Electronics' latest pulse withstanding chip resistor. It is available now from TTI Europe. The resistor is essentially a variant of the existing PWC with no laser trimming applied. This maximises the level of surge performance available in a single-sided flat chip design.
The device can withstand up to 6.5kV peak for a 1.2/50µs surge and up to 3kW for a 0.1ms pulse. The resistor is ideal for protection and discharge applications in compact power supplies and power control circuits where a resistance tolerance of 5% is adequate.
The device offers high stability and reliability, saving PCB area compared to multiple chip solutions to achieve the same pulse performance.
