Product Description
EWWR Axial Lead Wirewound Resistors
The EWWR series is an economical axial lead wirewound resistor offering flexibility in circuit design due to its small size. It provides a range of power options from 2W to 21W, resistance values from 1.2 to 9.3K, and a tight tolerance of 5%. With a maximum operating temperature of 260 and good heat resistance, these resistors ensure stable operation in high-temperature environments and applications requiring long-term loads, demonstrating high product reliability. They are suitable for precision instrumentation, semiconductor testing, medical equipment, and capacitor charging & discharging applications.
