Metal Film Resistors, Axial, High Precision, High Stability
FEATURES
• Extremely low temperature coefficient of
resistance
• Very low noise and voltage coefficient
Available
• Very good high frequency characteristics
• Can replace wirewound bobbins
• Proprietary epoxy coating provides superior
moisture protection
• For surface mount product, see Vishay Dale’s Available
PSF datasheet (www.vishay.com/doc?30162)
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
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.

Continuous working voltage shall be P x R or maximum working voltage, whichever is less.
Hot solder dipped leads.
For operation of the PTF resistors at higher power ratings, see the Load Life Shift Due to Power and Derating table. This table gives a
summary of the effects of using the PTF product at the more common combinations of power rating and case size, as well as quantifies the
load life stability under those conditions.
