Product Overview
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.
- Power rating at 25°C is 3W
- ±1%, ±2% and ±5% tolerance
- Operating temperature range -55°C to 200°C
- Temperature coefficient is <lt/>±75ppm/°C
