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 CECC 40-201-006
• 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 m available
• Low temperature coefficient ± 50 ppm/°C
• Electrical insulation
• Climatic protection
• Termination = Pure matte tin or Sn/Ag/Cu according to the
ohmic value
• Material categorization: for definitions of compliance

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:
