270 Series Vitreous Enamel Power F e at u r e s Select 270 Type fixed resistors for applications requiring wattage ratings from 12 to 1000 watts. The 270 Type resistors are equipped with lug terminals suitable for soldering or sturdy bolt connection. When secure mounting is required, the hollow core of these resistors permit fastening with spring-type brackets, thru bolts or thru bolts with slotted-steel brackets. Suitable for rugged applications, the 270 Type resistors feature all-welded construction and durable lead free vitreous enamel coating. Mounting brackets not included with resistors. • Terminals suitable for soldering or bolt connection • High wattage applications • Rugged lead free vitreous enamel coating • Flame resistant coating • All-welded construction • RoHS compliant available • “Fast on” option – see terminal 538, http://www.ohmite.com/techdata/terminals.pdf S ER I E S S P E C I F I C AT I O N S Series L12 L25 L50 L100 L175 L225 L500 L1000 Wattage 12 25 50 100 175 225 500 1000 Ohms 0.1-51K 0.15-100K 0.38-260K 0.23-101K 0.13-101K 0.16-129K 0.38-218K 0.69-392K Core Code D K K M P P S S Voltage 565 625 1625 2845 3595 4595 4970 8900 Std.

Large models (500 watts and up) are supplied in Silicone Ceramic. Also available in low-cost Centohm coating; Consult factory. Core Tubular ceramic. Terminals Solder coated radial lug. RoHS solder composition is 96% Sn, 3.5% Ag, 0.5% Cu Derating Linearly from 100% @ +25°C to 0% @ +350°C. Tolerance ±5% 1Ω and over (J); ±10% under 1Ω (K) Power rating Based on 25°C free air rating. Overload 10 times rated wattage for 5 seconds. Temperature coefficient 1 to 20Ω: ±400 ppm/°C; Above 20Ω: ±260 ppm/°C Dielectric withstanding voltage 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 to 225 watt rating (Measured from terminal to mounting bracket) Max. amps use the formula √P/R Power limitations for When resistance exceeds the resistance values listed, derate the Power Rating by 25% to high resistance values improve reliability. No power derating necessary for ratings higher than 100W.
