Insulated Precision Wirewound Resistors
Axial Leads
In wirewound precision resistors, the RLP series holds a
leading position in professional applications whenever an
excellent stability of the ohmic value and a correspondingly
low temperature coefficient are required at the same time.
The RLP model resistors comply with the most stringent
requirements of the EN 140-100 specification. The series
consists of 5 models covering the power range from 1 W to
10 W.
Non-inductive versions can be supplied on request by
specifying RLP-NI. For higher power dissipations, the use of
RH series resistors is recommended.
