1. INTRODUCTION
The earliest and most popular type of resistor is carbon film
resistor which can be used in almost all kinds of electronic
products. The resistive element is a high grade ceramic rod
on which a homogenous film of pure carbon is deposited by
vacuum heating process to pro-duce electricity conductivity
on the surface. Fully automation and mass production on
capping, sorting, cutting, welding, coating and double-checking
which comes out stable quality, high reliability and economic
cost for
SYNTON-TECH’s
CR series.

(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
)
