The product is essentially the evolution of a company's PWC (Pulse Carrying Chip) resistor, but the resistance is adjusted by precise process control instead of laser trimming, which can cause current crowding.

TT said: "This process maximizes the surge performance of unilateral planar designs." The HPWC series is suitable for protection and discharge applications in low-power and power control circuits requiring 5% tolerance.
& ;
HPWC resistors are available in sizes from 0805 to 2512 and can withstand peaks up to 6.5kV to 1.2 / 50μs and up to 3kW in 100μs.
& ;
Resistance from 1Ω0 to 100kΩ, 0805 to 2512 four sizes, rated from 0.25 to 2W.
& ;
Predictable applications include industrial and medical input protection, power supplies, circuit breakers, motor drives and medical monitors.
