Usability
In selecting a trimmer for a specific application, it's important to
be aware that the catalog contains a myriad of facts about each
model that can assist you in finding the most suitable choice. For
example:
154
Contact Resistance Variation (CRV) — Under MIL-R 22097
and MIL-R-39035, the maximum CRV is 3 %. All Bourns®
trimmers meet this standard (3 % or 3 ohms, whichever is
greater). For applications that demand a more rigorous
standard, some Bourns® trimmers are rated at 2 % or 2 ohms,
and many others at 1 % or 1 ohm.
Power Rating — The ambient temperature at which the
trimmer will operate has an important bearing on power
rating. Power ratings are usually specified at 70 ° or 85 °C; at a
temperature of 150 °C, the power rating of many trimmers is
reduced to zero.
Temperature Coefficient of Resistance (T.C.) — This
specification is a measure of how much the resistance changes
with a change in temperature. In many applications a T.C. of
±250 PPM/°C is acceptable. Typical T.C. specifications for
cermet models are ±100 PPM/°C and ±50 PPM/°C for
wirewound models.
