Metal Film Resistors, Industrial, Precision
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 ± 5 ppm/V
• Special tolerance and or TC matching
available on request
• Material categorization: For definitions of
compliance please see
www.vishay.com/doc?99912
Note
* Lead (Pb)-containing terminations are not RoHS-compliant.
Exemptions may apply.
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).
Note
(1)
Continuous working voltage shall be or maximum working voltage, whichever is less
Note
(2)
See the load life shift due to power and derating table for a summary of the more common combinations of power rating, case size and
ambient operating temperature that prevail in various industrial and military resistor specifications. The “performance” table quantifies the
load life stability under these combinations.
Notes
(3)
Tolerances of ± 0.5 % (D), ± 0.25 % (C) and ± 0.1 % (B) are available only in 50 ppm and 25 ppm temperature coefficients.
