Note:
The extended range GP1/4 series is designed to meet requirements where metal film
performance is needed at resistance values not normally attainable with deposited ni-chrome
films. Resistance values between 1.01 meg ohms and 20 meg ohms are available with
temperature coefficients of 50 PPM/ C and resistance tolerances of 0.1%. Marking is either
five band color code per EIA Standard RS-196A or four line alpha-numeric. Packaging is lead
tape and reel or ammo-pack per EIA Standard RS-296D. Bulk packaging is also available.
