Insulated Precision Wirewound Resistors
Axial Leads
FEATURES
• 1 Watt to 10 Watt at 25 °C
• CECC 40201-006
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.
• Conforms to NF C 83-210
• Excellent stability
• High power
• Low ohmic values
• Low temperature coefficient
• Electrical insulation
• Climatic protection

TYPICAL VALUE
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 2000h life test made under the 90’/30’ conditions
and at an ambient temperature of 25°C, are:
