Wire-wound resistor 1.5 Ω 10 W ±5% – EB1309667686

Wire-wound resistor 1.5 Ω 10 W ±5% is a precision passive component designed to provide stable resistance and dissipate up to 10 watts of power in electrical and electronic circuits. The device offers a nominal resistance of 1.5 ohms with a tolerance of ±5%, making it suitable where predictable current limiting and heat dissipation are required. Constructed with a wound resistive element, this resistor is intended for use in power circuits, load banks, test fixtures, and prototypes that demand reliable performance under moderate thermal stress.

Advantages

The wire-wound construction provides low noise, good stability over time, and strong pulse and overload tolerance compared with film resistors of similar ratings. Its 10 W power rating allows sustained dissipation in applications with continuous current flow, while the ±5% tolerance balances cost and accuracy for many industrial and laboratory tasks. The resistor’s physical design aids heat transfer to the surrounding environment and supports secure mounting in panel or chassis assemblies.

Suitable for

• Power supplies and current limiting circuits
• Load banks and dummy loads for testing
• Audio and industrial equipment requiring low-resistance elements
• Prototyping and replacement in power-handling circuits

Key specifications

• Resistance: 1.5 Ω
• Power rating: 10 W
• Tolerance: ±5%
• Type: wire-wound resistor
• Typical applications: power dissipation, current limiting, load simulation

How to use

Install the resistor according to the circuit schematic, observing correct polarity where applicable for the overall circuit (resistors are non-polar). Ensure adequate mechanical fastening and firm electrical connections to minimize contact resistance. Allow for sufficient ventilation or heatsinking as needed; because the component dissipates power as heat, mount it on a chassis or provide air circulation to keep operating temperatures within safe limits. Verify that the expected power dissipation and ambient conditions do not exceed the resistor’s ratings before prolonged operation.

Usage recommendations

For reliable long-term performance, avoid exceeding the maximum continuous power rating and operate within the specified tolerance range. When used in high-current or pulse applications, evaluate peak dissipation and consider additional cooling or a higher power-rated part. Check mounting orientation and clearances to prevent nearby components from overheating.
