THESE WERE MOSTLY MANUFACTURED BY ARCOL, ONE OR 2 VALUES MAY BE MADE BY OTHER  MANUFACTURERS, BUT WILL BE OF A SIMILAR  HIGH SPECIFICATION.

Powerful, durable and reliable, the 25-watt Arcol HS25 series aluminum housed resistor is designed for direct attachment to heatsinks. The wire-wound structure maximises the product’s high-pulse characteristics, ensuring optimal performance.

This makes the Arcol HS25 housed resistor ideal for applications that require high power dissipation in an enclosed space. The resistor is fitted via two screws and when in use, it dissipates power linearly to zero, even at scorching temperatures.

Manufactured to meet the requirements of MIL 18546 and IEC 115, the aluminum housed power resistor is a truly versatile product that can improve the heatsinking process.

Power rating: 25W(HS25), 50W(HS50)
Resistance tolerance: ±5%
Limiting element voltage: HS25:550V HS50:1250V
Temperature coefficient: <1K=100ppm/°C >1K=25ppm/°C
RoHS compliant

Resistor Range in Ohms:

R05, R1, R18, R22, R47, R82, 1R, 2R2, 3R3, 4R, 4R7,  5R, 10R, 15R, 22R, 33R, 47R, 68R, 100R, 220R, 470R, 680R, 1K, 2K2, 4K7, 10K

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, stored with us still in their original packaging, the photographs are representative of their excellent condition, being of one of our actual stock, and, as with all our products they come with a full guarantee.
