TT Electronics Welwyn Components has expanded its VRW series of RoHS compliant, high-voltage thick-film resistors with the VRW68, which offers a power rating of 1W. The series provides working voltage ratings of 1.6 and 3.5kV and high-pulse withstand capability of 10kV. Suited to harsh operating environments, the line-up has an ambient temperature range of -55 to 155degC.
Within the series parts are available that meet all BS/EN/IEC 60065 safety requirements and all resistors feature a robust thick-film construction with UL94-V0 cement coating that will not burn under any condition of applied temperature or overload.
The series is ideal for bleed resistor, mains motor control and lighting ballast applications.
