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 CECC 40-201-006 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.
FEATURES
•1 W to 10 W at 25 °C

•According to MIL-R-26/5C and MIL-R-26/6C
•Excellent stability < ± 0.3 % after 1000 h
•High power up to 10 W at 25 °C
•Low ohmic values 10 mΩ available
•Low temperature coefficient ≤ ± 50 ppm/°C
•Electrical insulation
•Climatic protection
•Termination = Pure matte tin or Sn/Ag/Cu according to the
ohmic value
•Compliant to RoHS directive 2002/95/EC

STABILITY AND POWER RATING
Stability changes slightly according to power rating and ambient temperature. This fact is especially important for users needing
a life drift lower than the initial resistance tolerance. Typical drifts, after 2000 h life test made under the 90’/30’ conditions and at
an ambient temperature of 25 °C, are:
