All resistors are in ohms.
kQ =1000Q , MQ =1000KQ
Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power % W
Exel ; nontlammable resistor.
{WAGE : fusible resistor.
A: internal component.
[_] : panel designation, or adjustment for repair.
All variable and adjustable resistors have characteristic curve
