Note
* This datasheet provides information about parts that are RoHS-compliant and/or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information/tables in this datasheet for details.
Vishay Dale Model CMF is also available as Military Qualified Styles RN and RL. See Vishay Dales CMF (Military RN and RL)
datasheet (www.vishay.com/doc?31027) for the MIL-SPEC ratings / attributes. (Except for marking, the Industrial and Military
versions are exactly the same).
