Wirewound Power Resistor 100 Ω 15W ±5% (EB827294614)

The Wirewound Power Resistor 100 Ω 15W ±5% is a through-hole mounted resistor designed for applications requiring stable resistance and the ability to dissipate moderate amounts of heat. Constructed with a wirewound element and robust body, this component provides reliable performance for power dissipation, load testing, current limiting and circuit prototyping. Its 100 Ω nominal resistance and 15 W power rating make it suitable for use in power supplies, motor drives and a variety of industrial electronics where continuous or intermittent power handling is required.

Advantages

The resistor offers a combination of precise resistance and good thermal handling due to its wirewound construction, which yields stable electrical characteristics under load. Its ±5% tolerance balances accuracy and cost, while the 15 W power rating allows for sustained dissipation in compact assemblies. The through-hole form factor and robust mechanical design simplify mounting and improve long-term reliability in demanding environments.

Suitable for

• Power supplies for load balancing and surge testing
• Motor drive circuits for current sensing and limiting
• Industrial control electronics and power conversion prototypes
• Bench load testing and circuit prototyping

Key specifications

• Resistance: 100 Ω nominal
• Power rating: 15 W continuous
• Tolerance: ±5%
• Construction: wirewound resistive element
• Mounting style: through-hole
• Thermal dissipation: designed for moderate heat loads with robust body

How to use

Install the resistor in a through-hole PCB or on a suitable mounting bracket ensuring adequate clearance for heat dissipation. Provide free airflow or a heatsink if the resistor will operate near its 15 W rating for extended periods. When integrating into circuits, consider the ±5% tolerance for precision applications and verify power dissipation calculations against expected currents and voltages to avoid overheating. Use appropriate soldering practices for through-hole components and avoid mechanical stress on leads after soldering.

Usage recommendations

Operate the resistor below or at its rated power whenever possible and allow sufficient time for cooling after high-power use. Ensure good ventilation or additional cooling in enclosed assemblies, and account for tolerance in designs where exact resistance values are critical.
