Choose Ohmite’s 210 Type adjustable resistors for
applications requiring settings at different resistance
values. These wirewound resistors are equipped with
an adjustable lug, making them ideal for adjusting
circuits, obtaining odd resistance values and setting equip ment to meet various line voltages. 210
Type resistors feature a hollow core to permit secure
fastening with spring-type clips or thru bolts with
washers. They also offer the durability of lead free
vitreous enamel coating and all-welded construction.
Mounting brackets not included with resistors.

characteristics
Adjustability 10% to 90% of full value. Wattage is proportional to this adjusted
resistance value.
Coating Lead free vitreous enamel.
Core Tubular ceramic.
Terminals Solder coated radial lug. RoHS solder composition is 96% Sn,
3.5% Ag, 0.5% Cu
Adjustable Nickel plated steel. (Screwdriver type adjustable lug supplied
terminal standard. Other types, including silver contact units, available.)
Derating Linearly from 100% @ +25°C to 0% @ +350°C.
Tolerance ±10% (K)
Power rating Based on 25°C free air rating. The stated wattage rating applies
only when the entire resistance is in the circuit. Setting the lug at
an intermediate point reduces the wattage rating by approximately
the same proportion. Example: If the lug is set at half resistance,
the wattage is reduced by approx. one-half.
Overload 10 times rated wattage for 5 seconds.
Temperature ±260 ppm/°C
coefficient
Dielectric 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt ratwithstanding ing (measured from terminal to mounting bracket)
voltage
Max. amps To calculate, use the formula √P/R.
