Series 392 Immersible
0.5-Watt Potentiometers
Economical potentiometer designed to meet wave soldering applications
for mounting to PC boards. Meets flow solderability and washability test
requirements. MIL-R-94 standards apply where applicable. Resistance
Tolerance: Linear, up to 1 M½ ±10%, above 1 M to 5 M ±20%. Tapers, up
to 250 K ±10%, above 250 K to 5 M ±20%. Resistance Range: 100 ½ to
5 M½, linear; 500 ½ to 2 M½, tapered. Power Rating: 0.5 watt maximum
continuous power rating for linear taper, but voltage not to exceed rating.
Working Voltage: 350 VDC across end terminals, but power not to exceed
rating. Linearity: ±5% Independent. Torque Range: 0.20 to 2.0 oz. in.
Shafts, Standard: 0.125 dia. Solvent Resistance: Housing resistant to
trichlorethylene, chlorethene, NU Freon TMS, Freon TMC, carbon tetrachloride, toluene, MEK ethyleacetate and gasoline.

The CR series of rheostats is ideal for use over long periods of time. Features vitreous enamel to bond the core and base, wiper tracks are
buffered to assure smooth rotation and uniform contact, three terminals for potentiometer applications, and minimum backlash. The series is
made in accordance to MIL-R-22. The 25 and 50 watt models are UL approved. The 12.5 watt units are not UL approved. Resistance
Tolerance: ±10%. High strength ceramic hub insulates the shaft and bushing from all line parts.
