With extremely low resistances and high power capabilities,
VISHAY’s proven and unique ultra-low value resistors
can be used in your hybrid or surface mount applications.
These resistors are available with solderable or weldable
terminations.
CONSTRUCTION
FEATURES
•Lead (Pb)-free or Sn/Pb terminations available
•Homogeneous nickel alloy film
•No inductance for high frequency application
•Alumina substrates for high power handling capability
(2 W max power rating)
•Pre-soldered or gold terminations
•Epoxy bondable termination available
TYPICAL PERFORMANCE
(Resistor values beyond ranges shall be reviewed by the factory)
* Pb containing terminations are not RoHS compliant, exemptions may apply
