W21-240RJI

WELWYN  W21-240RJI  通孔电阻器, W21系列, 240 ohm, 3 W, ± 5%, 100 V, 轴向引线

The Welwyn W21 series wirewound resistors are highly stable and reliable resistors offering high power and resistance in a small size. The Resistance range includes E24 decade values from 1ohm to 10 ohm. W21 series are suitable for use in harsh environments and Ideal for protection circuits. A high purity ceramic substrate is assembled with interference fit end caps to which are welded the termination wires. The resistive element is wound on substrate and welded to caps.
