Another point to remember about using resistors as fuses is that unless the manufacturer guarantees the fusing current, time and prospective fault voltage, you haven't a clue if the results are repeatable from batch to batch - or even from resistor to resistor. A change in manufacturing process (or factory) can mean totally different results. And if you test the part for fusing capability, you can't use it afterwards! 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
