TT Electronics WA80 Cement Coated Wirewound Resistors

TT Electronics / Welwyn WA80 Cement Coated Wirewound Resistors use a wirewound resistive element on a ceramic substrate with cement protection and hot tin dipped copper wire terminations. The WA80 series provides limiting element voltages up to 150V and isolation voltages up to 500V. These general purpose resistors operate within a temperature range from -55°C to +200°C. WA80 resistors are specified for pulse handling applications and applications where carbon composition resistors can be replaced.
