VRW37-470KJI

WELWYN  VRW37-470KJI  通孔电阻器, VRW系列, 470 kohm, 500 mW, ± 5%, 3.5 kV, 轴向引线

The VRW series from Welwyn are high voltage thick film resistor with robust flame proof coating. It has hot tin dipped copper wire material, this resistive thick film material is applied to high-grade ceramic rods. Tin-plated steel caps are force fitted and the termination wires are welded to the caps. The value is obtained by a helical cut in the film and finally the resistor body is protected by a cement coating. The terminations meet the requirements of IEC 68.2.21 strength and meets the requirements of IEC 115-1 Clause 4.17.3.2 solderability.
