Unique-Bargains 10 Pcs Metal Oxide Film Resistor 2 Ohm 5W 5% Axial

Metal oxide film resistor kit

This pack contains ten axial metal oxide film resistors rated at 2 ohm with a 5 watt power rating. The 5% tolerance parts are suited for DIY electronic projects and experiments where higher pulse handling is needed. Metal oxide construction provides better surge and temperature performance than carbon or metal film types. The axial lead form factor fits standard through-hole prototyping boards.

Upgrade from carbon or metal film resistors

These resistors replace lower-rated carbon or metal film parts when circuits demand higher power dissipation, voltage withstand, or surge capability. The jump is worth it for designs that encounter transient spikes or sustained loads near the 5 watt rating. They also serve as direct replacements in series or parallel power-load arrangements where standard film resistors may drift or fail. The flame-proof coating adds a safety margin in fault conditions.

Limits of axial through-hole format

The axial lead spacing and body dimensions (24.5 mm by 8.0 mm) require adequate board clearance and hole spacing for mounting. Maximum working voltage is 500 V with a 1000 V overload rating and 1500 V pulse rating, so circuits exceeding these levels need alternative construction. Dielectric withstanding voltage is 700 V, limiting isolation applications. Operating temperature range extends to the stated extremes, but thermal management depends on PCB copper area and airflow not defined by the component alone.
