Axial Lead Wirewound Resistors

The RESI EWWR Series is a coated wirewound fixed resistor designed for high-power applications requiring stable performance and compact axial mounting. Manufactured using wirewound technology, the series provides reliable resistance performance across a resistance range from 0.1Ω to 8.2kΩ. With rated power options from 1W to 10W, a tolerance of ±5% and a TCR of ±250ppm/℃, the EWWR Series is suitable for circuits where power handling, pulse capability and dependable operation are required. The source description identifies the series as small in size, with anti-pulse ability and stable performance for varied operating conditions. The resistor uses an axial leaded format and is packaged with non-flammable paint, supporting safe and reliable operation in high-power designs. The EWWR Series operates across -55°C to +155°C and is RoHS compliant.
