INSULATED MOLDED
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 coeffi cient are required at the same time.
The RLP model resistors comply with the most stringent
requirements of the NF C 83-210 specifi cation.
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.

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:
