Arcol, 3.9Ω 25W Wire Wound Chassis Mount Resistor HS25 3R9 J ±5%

From Arcol, the HS25 series of aluminium housed resistors are high power and offer a balance of pulse power capability and volume. These 25 W panel mount resistors are manufactured in line with IEC 115 and MIL 18546. These panel mount resistors are designed for direct heatsink mounting with thermal compound, which ensures maximum performance.

At high ambient temperatures, dissipation derates linearly to zero at +200 °C

To achieve the given maximum performance rating of this power resistor, it is designed to be directly mounted on an appropriately matched heatsink and mounted using a thermal compound.

For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
