Five green aluminium chassis-mount wirewound resistors with mounting flanges

Unique-Bargains

Unique-Bargains 25W 2 Ohm Aluminium Chassis Mount Wirewound Resistor Green 5pcs

SKU CH-NR8E-VJHFN

A pack of five chassis-mount wirewound resistors rated at 2 Ω and 25 W each, with aluminium housings for heat dissipation

  • 25 W power rating handles demanding circuits
  • Aluminium housing dissipates heat for stable operation
  • Chassis-mount design with 3.5 mm screw holes secures installation
  • ±5 % tolerance on 2 Ω resistance ensures precise values
  • Pack of five resistors supports multiple builds

25 W 2 Ω Chassis Mount Resistor Pack

These aluminium-housed wirewound resistors handle 25 W each at 2 Ω with ±5 % tolerance. The green anodised casing measures 53 × 27 × 15.5 mm overall and uses a 3.5 mm mounting hole for direct chassis attachment. Five pieces are supplied for prototyping or service replacement.

Suits High-Power Dissipation Needs

Designers who need reliable heat sinking in power supplies, transducer circuits or industrial audio equipment will value the aluminium body and ceramic core. Buyers requiring lower power ratings, different resistance values or surface-mount formats should look at other component types.

25 W Power Rating Decides Fit

The 25 W continuous dissipation rating is the single figure that determines whether this part survives your circuit. Verify your maximum expected power against this limit before ordering.

Questions about this item

What mounting hardware do I need to install these 3.5 mm chassis-mount holes?

You will need screws that fit a 3.5 mm hole and a flat metal surface or cooling plate to bolt the aluminium housing against for heat dissipation.

Can I replace a single 25 W 2 Ω wirewound resistor with one from this pack without changing the circuit?

Yes, each unit is rated at 2 Ω ±5 % and 25 W, so it directly substitutes an existing resistor of the same value and power rating.

How can I verify the resistor is performing correctly after mounting it?

Measure the resistance with a multimeter — it should read between 1.9 Ω and 2.1 Ω — and confirm the aluminium body stays within safe temperature during operation.
