FUSIBLE FIXED RESISTORS
•
Non-flame coating, raw materials used for
F
usible
R
esistors are that

R
esistors
•
Ideal circuit opening controller, disconnecting units from overload
rating specified
•
Too low or too high ohmic value can be supplied on a case to case
basis
Ordering Procedure: (Ex.: FRN 1W, +/-5%, 10

, T/B-1000)
F R N 0 1 W J 0 1 0 0 A 1 8
Resistor Type:
Wattage:
FRN = Fusible Fixed Resistors
W4 = 1/4W
W2 = 1/2W
1W = 1W
Special Feature:
2W = 2W
0 = Standard Product
3W = 3W
S2 = 1/2W-S
Resistance Value:
E-24 series: the 1
st
digit is “0”, the
2
nd
& 3
rd
digits are for the significant
figures of the resistance and the 4
th
indicate the number of zeros:
“J” ~ 0.1, “K” ~ 0.01
Ex.
4.7
Ω
~ 47J, 4.7K
Ω
~ 472
Packing Type:
