RLP Vishay Sfernice Insulated Precision Wirewound Resistors Axial Leads FEATURES * 1 W to 10 W at 25 C * CECC 40201-006 RoHS * Conforms to EN 140-100 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. COMPLIANT * Excellent stability < 0.3 % after 1000 h * High power up to 10 W at 25 C * Low ohmic values 10 m available 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. * Low temperature coefficient 50 ppm/C * Electrical insulation * Climatic protection * Termination = Pure matte tin or Sn/Ag/Cu according to the ohmic value DIMENSIONS in millimeters INSULATED 25 min.
