Resistor 3.3k ohm 15W

The Resistor 3.3k ohm 15W is a high-power fixed resistor with a resistance of 3.3 kΩ and a power rating of 15 W. Its large power rating lets it handle heat that would burn out ordinary 0.25 W or 0.5 W resistors, so it is used to bleed high-voltage capacitors, load power supplies and limit current in power electronics and industrial equipment.

Resistor 3.3k ohm 15W Specifications

• Resistance: 3.3 kΩ (3,300 ohms)
• Power rating: 15 W
• Voltage at full power: about 222 V (V = √(P × R))
• Current at full power: about 67 mA
• Type: high-power fixed resistor
• Polarity: none

Resistor 3.3k ohm 15W Applications

• Bleeder resistors that discharge filter capacitors in power supplies and amplifiers
• Dummy loads for testing power supplies
• Current limiting and voltage dropping in higher-voltage circuits
• Motor control, heating and industrial electronics
• Repairing inverters, UPS units and power boards

What's in the Box

• 1 × 3.3 kΩ 15 W resistor

Tip: A resistor working near 15 W gets very hot, so mount it away from plastic, wires and other parts, and run it at about half its rating for continuous use. Check the power with P = V² ÷ R: for example, 100 V across 3.3 kΩ gives about 3 W.
