330 Ohm 1W 5% Carbon Film Resistor Axial Through-Hole

Product Overview

The 1W Carbon Film Resistor is the higher-power member of the carbon film family, built on a larger ceramic core than the 1/4W and 1/2W versions to safely dissipate more heat. It uses the same proven carbon film deposition process, giving reliable performance at a low cost.

Why choose 1W?

When a circuit needs to drop real power — not just signal-level current — the 1/4W and 1/2W ratings run hot and degrade over time. The 1W rating gives a comfortable safety margin for current-limiting, bleeder, and power-dropping applications where sustained dissipation is expected.

Technical Highlights

• Power Rating: 1 Watt @ 70°C — four times the headroom of a standard 1/4W resistor.

• Technology: Carbon Film (Axial Lead)

• Tolerance: ±5% (Standard 4-Band Colour Code)

• Operating Temp: -55°C to +155°C

• Dimensions: Larger body size for enhanced thermal performance.

Ideal Applications

• Power Supplies: Bleeder resistors for discharging filter/X-Y capacitors.

• Current Limiting: LED strings, snubber networks, gate/base resistors carrying higher current.

• Motor & Relay Circuits: Flyback damping and coil bias at higher power.

• Audio Electronics: Attenuator pads and crossover networks handling real signal power.

Key Features

• High Power Handling: Safely handles continuous loads up to 1 Watt without degradation.

• Enhanced Durability: Thicker epoxy coating resists humidity and thermal shock.

• Low Noise: Optimised carbon film structure for stable, quiet operation.

• RoHS Compliant: Lead-free construction, safe for commercial and hobbyist use.
