New resistors for the power industry | Engineer Live

HPWC resistors are available in 4 sizes, from 0805 to 2512, which can withstand up to 6.5kV peak with 1.2/50us surge and up to 3kW with 0.1ms pulse. This product is essentially an improvement of TT Electronics' PWC (pulse resistant chip) resistor, but its resistance value is adjusted through precise process control rather than laser trimming. This process maximizes the surge performance available in single-sided flat chip designs. The available resistance values ​​range from 1R0 to 100K, there are 4 sizes from 0805 to 2512, and the rated values ​​range from 0.25 to 2W.

These high-energy chip resistors have an enhanced ability to absorb high-energy surges and are ideal for input protection of power supplies, circuit breakers, motor drives and medical monitors. Therefore, thick film resistors are aimed at designers of compact SMD circuits in power conversion, motion control and protection applications in the industrial and medical markets.
