100W 2.7Ω Wirewound Resistor

This 100 watt wirewound resistor with a 2.7 ohm resistance and 5 percent tolerance suits engineers and hobbyists working on LED replacement converters, motor speed controls, inverters and other AC or DC circuits. The aluminum housed construction provides the thermal management needed for continuous high power operation.

Aluminum Case With Mounting Holes

The resistor body measures 59 millimetres long and uses an aluminum case to dissipate heat directly instead of trapping it under an insulated cover. Two rods with 2 millimetre holes allow soldered connections while a 3.2 millimetre diameter anchoring hole accepts M2.3 hardware for secure chassis mounting.

Upgrade From Lower Power Resistors

Replaces smaller wirewound or carbon film resistors that cannot handle sustained 100 watt loads or that overheat in enclosed converter designs. The jump is worth it when a circuit demands stable resistance at full power without thermal drift or when physical mounting must survive vibration in industrial driver applications.

Questions about this item

What power does the 2.7 Ω wirewound resistor handle before it overheats?

The aluminium-cased unit is rated for 100 W continuous dissipation; the metal housing conducts heat away from the winding so the element stays within its thermal limits.

Which mounting holes match the 59 mm body for a secure fit?

Two 3.2 mm diameter antisymmetric holes accept M2.3 or #2 screws, spaced to the 59 mm main-body length for direct PCB or chassis mounting.

How are the leads soldered without melting the insulation?

Insert the two 2 mm rods through the board, solder quickly with a temperature-controlled iron, and avoid excessive dwell time so the aluminium case remains the primary heat path.
