RLP Vishay Sfernice Insulated Precision Wirewound Resistors Axial Leads FEATURES * 1 Watt to 10 Watt at 25 C * CECC 40201-006 * Conforms to NF C 83-210 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 NF C 83-210 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. * Excellent stability * High power * Low ohmic values * Low temperature coefficient * Electrical insulation * Climatic protection DIMENSIONS in millimeters INSULATED 25 min. 45 chamfer max. 0.25 deep 25 min.
