There are some similarities between Resistors and Fuses in
material and structure. Fusible Resistors contain both
functions, as being resistor in normal condition and changed
into fuse while abnormal current comes in protect machines
and equipment. Since two functions performed by one resistor,
the cost therefore saved.
SYNTON
fusible resistor series
are produced with precision technique to get exact fusing time.
It is also for telephone sets which demand 600V.
2. FEATURES
It is suitable for protecting circuit boards.
Small in size.
Noncombustible insulating coat.
Low temperature coefficient.
Uniform in fusing time.
Body coating is in gray or green, with 4 or 5 color
bands or stamping.
Too low or too high ohmic value can be supplied
only case by case.
