Vishay Dale
Metal Film Resistors, High Precision, High Stability, Surface Mount
FEATURES
• Extremely low temperature coefficient of
resistance
• Molded encapsulation
• Wraparound compliant terminations eliminate
the risk of solder fillet cracking
• Solderable terminations
• Excellent stability at different environmental
conditions
• For axial-leaded product, see Vishay Dale’s
PTF datasheet (www.vishay.com/doc?31019)
• 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.
