KNP Series Wirewound Resistor

Manufacturer: Guangdong Qingda Electronic Technology Co., Ltd
Product Overview

KNP series wirewound resistor is a flameproof axial lead fixed power resistor developed and produced by Guangdong Qingda Electronic. Adopting high-quality alloy resistance wire wound on high-temperature ceramic core and coated with flame-retardant insulating paint, KNP wirewound resistors feature compact structure, low temperature coefficient, low noise and outstanding pulse load resistance. Compared with ordinary film resistors, KNP resistors perform far better in instantaneous surge resistance and heavy-load stability.
With complete power specifications and stable electrical performance, KNP wirewound resistors are cost-effective general-purpose power resistors. They are widely used for current limiting, load discharging, over-current protection and circuit sampling in consumer electronics, power adapters, lighting ballasts, power tools and industrial control equipment. All products comply with RoHS lead-free standards, and custom resistance values and specifications are available.
