Insulated Precision Wirewound Resistors Axial Leads
FEATURES
1 W to 10 W at 25 C
Approved according to CECC 40-201-006
According to MIL-R-26/5C and MIL-R-26/6C
In wirewound precision resistors, the RLP series holds a
Excellent stability < 0.3 % after 1000 h
leading position in professional applications whenever an
High power up to 10 W at 25 C
excellent stability of the ohmic value and a correspondingly
Low ohmic values 10 m available
low temperature coefficient are required at the same time.
Low temperature coefficient 50 ppm/C
The RLP model resistors comply with the most stringent
Electrical insulation
requirements of the CECC 40-201-006 specification. The
Climatic protection
series consists of 5 models covering the power range from
1 W to 10 W.
Termination = Pure matte tin or Sn/Ag/Cu according to the
ohmic value
Non-inductive versions can be supplied on request by
Material categorization: for definitions of compliance
specifying RLP-NI. For higher power dissipations, the use of
