정밀급 권선저항기는 특수자기봉에 금속합금 저항선을
권선하여 고내열성의 불연성 실리콘 도료로 도포한 정
밀급 소형 고전력 저항기로써 정밀전원 회로에 적합합니다.

RW/RWN type resistor is wound with a single layer of
resistance wire on a ceramic steatite or alumina core and
protected by special high temperature silicone coating.
This precision suminiature types, offering high power
dencity, are the most available for precision power circuit
applications.
