CMF Industrial
Vishay Dale
Metal Film Resistors, Industrial
FEATURES
• Small size - conformal coated
• Flame retardant epoxy coating
• Controlled temperature coefficient
• Excellent high frequency characteristics
• Exceptionally low noise; typically 0.10 µV/V
• Low voltage coefficient to ± 5ppm/Volt
• Special tolerance and or TC matching available on request
Vishay Dale Model CMF is also available as Military Qualified Styles RN and RL. See appropriate catalog or web page for the MIL-SPEC
ratings/attributes. (Except for marking, the Industrial and Military versions are exactly the same. Depending upon stock, military marked parts
may be supplied as industrial rated parts.)

**A 0.0005Ω bridge error is allowed in resistance measurement. It has the greatest effect on values in this range and should be taken into
account when verifying tolerance and Temperature Coefficient.
