Metal Film Resistors, Axial, Military, MIL-R-10509 Qualified,

Precision, Type RN and MIL-PRF-22684 Qualified, Type RL

FEATURES

• Very low noise (-40 dB)

• Very low voltage coefficient (5 ppm/V)

• Controlled temperature coefficient

• Flame retardant epoxy coating

• Commercial alternatives to military styles are available

with higher power ratings. See CMF Industrial data sheet:

(www.vishay.com/doc?31018)

Notes

(1) Continuous working voltage shall be

or maximum working voltage, whichever is less.

(2) Formerly rated at 1 W and is the direct replacement for RN70 of MIL-R-10509 rev. D.

(3) Tolerances of ± 0.1 %, ± 0.25 % and ± 0.5 % are not applicable to characteristic D.
