Unique-Bargains 50W 25 Ohm 5% Aluminum Housing Wirewound Resistor Chassis Mount Green

50W 25 Ohm Wirewound Resistor

This aluminium-housed wirewound resistor is rated at 50 watts with a 25 ohm resistance and 5 percent tolerance. It uses a chassis-mount design with screw terminals for secure attachment to a mounting plate or heatsink. The green anodised aluminium case aids heat dissipation in demanding environments. It is sold as a single component for electronics assembly or repair.

Suits high-power load and braking circuits

Engineers building power supplies, transducer drives, elevator controls or arena audio systems will find the 50 watt rating and vibration-resistant winding appropriate. The 25 ohm value also matches common ring-doorbell retrofit kits. Buyers who need a different resistance value, a lower power rating or a through-hole PCB mount should look at other parts.

Simple screw fixing, watch insulation

Two 3.5 mm mounting holes accept standard M3 screws; the body measures 49.5 by 27 by 15.5 mm with an overall length of 73.3 mm including terminals. Apply thermal compound between the aluminium case and the mounting surface for best heat transfer. Ensure the live terminals cannot touch the grounded chassis or adjacent components.
