These wirewound resistors are equipped with an adjustable lug, making them ideal for adjusting circuits, obtaining odd resistance values and setting equipment 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. ordering info Coating Blank = Vitreous C = Centohm S = Silicone RoHS Compliant sPeCiFiCatiONs Adjustability is 10% to 90% of full value. Wattage is proportional to this adjusted resistance value. Material 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 terminal: Nickel plated steel. (Screwdriver type adjustable lug supplied standard. Other types, including silver contact units, available.) Derating: Linearly from 100% @ +25°C to 0% @ +350°C. Electrical 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 approximately one-half. Overload: 10 times rated wattage for 5 seconds. Temperature coefficient: ±260 ppm/°C Dielectric withstanding voltage: 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt rating (measured from terminal to mounting bracket) To calculate max. amps: use the formula √P/R.
