  • Operating range of -55 to 155 °C suits demanding temperature environments

Metal oxide film resistors for DIY circuits

This pack contains thirty axial-leaded metal oxide film resistors rated at 39 kilohms with a five percent tolerance. They are intended for hobbyists and technicians building or repairing through-hole circuits where a two-watt flame-proof component is required.

Thermal and voltage limits in normal use

The resistors are specified for continuous operation up to two watts and can handle a maximum working voltage of 350 volts. They withstand overload peaks of 600 volts and pulse spikes of 750 volts while operating across a temperature range of -55 to 155 degrees Celsius.

Five percent tolerance defines selection

The single specification that decides suitability is the five percent resistance tolerance. Designs needing tighter precision or a different resistance value will not be served by this kit.

Questions about this item

How do I install these 39K ohm axial resistors on a PCB?

Insert the axial leads through the board holes, solder each joint, then trim the excess lead length; the common mistake is applying excessive heat that damages the metal oxide film coating.

What maintenance or replacement will these 2W metal oxide film resistors need over time?

They require no routine maintenance; replace any unit that shows discolouration, cracked body, or measures outside the 5% tolerance after sustained operation at the 350V working voltage.

Which limit appears first when these 39K ohm resistors run continuously at 2W?

The body temperature will reach the 155°C upper operating limit before the 350V dielectric withstanding voltage or 600V overload voltage ratings are exceeded.
