Note:
(1) _{The Continuous Current Rating applies only to values equal to or less than the Crossover Value. The Continuous Power Rating applies only}
to values equal to or higher than the Crossover Value.
Be aware that the inherent compromise involved between resistive and fusing functions sometimes makes certain exact combinations
unattainable. However, in nearly all cases, this does not prevent the production of a functional, reliable fuse resistor thoroughly capable of
meeting application requirements.

PACKAGING
If a MODEL listed in TYPICAL ELECTRICAL SPECIFICATIONS table does not meet your requirements, then please include the following
information. It will enable us to choose the best design for your application.
1. Operating wattage or current, ambient temperature and required resistance stability. (% ΔR/1000 hours.)
2. Fusing wattage or current and maximum “blow” time. Also, minimum “blow” time, if applicable.
3. Nominal resistance and maximum allowable resistance tolerance, (5 % to 10 % preferred).
4. Maximum allowable physical size.
5. Voltage to be interrupted.
6. Frequency of power source, wave form and a brief description of your application.
