1. INTRODUCTION
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 equioment.
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.
2. FEATURES
It is suitable for protecting circuit boards.
Small in size.
Noncombustible insulating coat.
Low temperature coefficient.
Uniform in fusing time.
Too low or too high ohmic value can be supplied
only case by case.

(2)Rated Voltage :
The DC or AC(rms) continuous working voltage
corresponding to the rated power is determined
by the following formula:
E
=
RxP
Where E : Continuous rated DC or AC (rms) working voltage (v)
P : Rated power (w)
R : Resistance value (
Ω
