Check the listing for details. 2pcs Aluminum Shell Resistor 100W 300Ohm Wirewound for LED Replacement Converter. Color: Gold Tone, Condition: New. Listed at 17.00 USD. Description: 100 Wattage and 300 Ohm, 5% tolerance. Wire Wound Resistor owns high stability and accuracy. Moreover, it was used for various application because of the wide resistance range. Aluminum Housed. An insulated cover on the wounded wires would block out the heat, which promises the high performance of a resistor. Hence, the cooling job was achieved by aluminum case. This 100W resistor formed with qualified copper, nickel, and aluminum. With the compact structure and heat dissipation design, a capability of overload has been built. Board length 2.32 inches(59mm) and two rods with 2mm hole for a soldering connection. Dia. 3.2mm antisymmetric anchoring hole for holding, which will fit #2 Screws(or M2.3 nuts) Reliable.
