RF - NIKKOHM

⾼周波⽤⾼電⼒抵抗器
FLANGED POWER RESISTORS

RFRF

特⻑ ⽤途Features and Applications
RF and microwave resistors of 50 to 800ohm haveflange cooling, also applicable for terminations instrip-line circuits.
Long life and temperature stability are a result of Ni-Cr
thin film and super heat conductive ALN ceramic
substrates.
Industrial RF power sources, RF amplifiers, radiotransmitters, fixed transmitter of mobile systems, andmeasurements.

２ビームリード端⼦，抵抗値 50Ωから 800Ωのフランジ付⾼周波電⼒⽤抵抗器．
超⾼熱伝導性，⽐誘電率約１０のセラミックスを絶縁物に使⽤した⾼周波抵抗器．定格電⼒ 100W, 150W．
⾼周波領域とマイクロ波領域で性能を発揮します．
⾼精度ＮｉＣｒ薄膜抵抗ですから，⾼周波領域で無誘導で，周囲温度による抵抗値の変化がきわめて少なく安定．
⾼周波増幅器，⾼周波電源，移動体通信固定局，無線送信機，計測機器，の吸収抵抗など．
