Unique-Bargains Aluminum Case Resistor 5W 90 Ohm Wirewound 2 Pcs

SKU CH-BR2F-SNHCB

Wirewound aluminum-housed resistors rated at 5 W and 90 Ω, supplied as a pair

  • 5 W wirewound power handles LED loads reliably
  • 90 Ω ±5 % tolerance suits converter speed control
  • Aluminium housed body dissipates heat without a fan
  • 9 cm long, 23 mm leads fit tight boards
  • Two pieces per pack for spares or dual circuits

Resistor for LED and Converter Use

Two 90 ohm wirewound resistors rated at 5 watts each. They suit hobbyists and technicians replacing load resistors in LED circuits or converter speed controls. The aluminium housing provides insulated thermal management. Pack contains two pieces.

Upgrade from Lower Power Parts

These replace smaller axial or carbon-film resistors that cannot dissipate 5 watts continuously. The jump is worth it when a circuit demands sustained power handling without overheating. The wirewound construction and metal case give stable resistance under load.

Capacity and Thermal Limits

Each unit handles 5 watts at 90 ohms with a 5 percent tolerance. Body length is 1.9 cm and lead length is 23 mm. They comfortably handle continuous dissipation in free air. They run out when ambient temperature or enclosure restricts heat flow from the aluminium case.

Questions about this item

What are the body length and wire length of each 90 ohm resistor?

The main body is 1.9 cm (0.75 inches) long and the connection wires measure 23 mm (0.9 inches).

How do I solder these wirewound resistors without damaging the aluminum case?

Use a temperature-controlled iron, apply heat briefly to the wire leads only, and avoid prolonged contact with the case to prevent internal insulation breakdown.

When should I replace these 5 watt resistors in an LED converter circuit?

Replace them if the case shows discolouration, the resistance drifts beyond the 5% tolerance, or the wire insulation becomes brittle from repeated thermal cycling.
