10W 4.5 Ohm Wire Wound Resistor

This aluminium-cased wire wound resistor handles 10 watts at 4.5 ohms with a ±5% tolerance. It suits repair or prototype work on power supplies, transducers, elevator controls and similar industrial equipment where reliable heat handling matters.

Chassis Mounting With Screw Tabs

Two screw tabs let you bolt the resistor directly to a chassis or heatsink for improved thermal transfer. The 0.2 cm mounting holes accept small machine screws; take care not to over-tighten or the aluminium body can distort and lose contact pressure.

4.5 Ohm ±5% Resistance Value

The single figure that determines fit is the 4.5 ohm nominal resistance with a 5% tolerance band. If your circuit calls for a different ohmic value or a tighter tolerance, this part will not meet the specification.

Questions about this item

How do I verify the 10 watt wire wound resistor is working correctly after mounting it to a heat sink?

Measure the resistance across the screw tabs with a multimeter; it should read 4.5 Ohm within the ±5% tolerance, and the aluminum case should stay cool enough to touch during normal 10 watt operation.

What comes in the box and do I need to buy mounting hardware separately?

The package contains the resistor with its gold-tone aluminum case and integrated screw tabs; you only need to supply your own screws or bolts that fit the 0.2 cm mounting hole.

Which resistance value and power rating should I choose for a 4.5 Ohm 10 watt application?

Select this exact model — it provides 4.5 Ohm resistance with a 10 watt power rating and ±5% tolerance, matching the specification for power supply, transducer or elevator equipment.
