TT Electronics’ HPWC (high pulse withstanding chip) range of high energy surge resistors maximize the level of surge performance available in a single-sided flat chip design. The HPWC range is suitable for protection and discharge applications in compact power supplies and power control circuits where a resistance tolerance of five percent is required.
Available in four sizes from 0805 to 2512, HPWC resistors withstand up to 6.5kV peak for a 1.2/50ms surge and up to 3kW for a 0.1ms pulse. The product is essentially an evolution of TT Electronics’ PWC (pulse withstanding chip) resistors but where the resistance value is adjusted by precise process control rather than by laser trimming. This process maximizes and improves the level of surge performance available in a single-sided flat chip design. Resistance values available are from 1R0 to 100K, and there are four sizes from 0805 to 2512, with ratings from 0.25 to 2W. For more resistance, visit TT Electronics’ HPWC resistors.
