TE Connectivity 3.9kΩ Carbon Film Resistor 0.5W ±5% CFR50J3K9

The CFR Series from TE Connectivity are a range of premium quality carbon film resistors whose ceramic core has a high alumina content offering superb power to size ratios, not typically associated with carbon film products. CFR Series are available in a range of power ratings from 1 ohm to 10 Mohm with the smallest case size (CFR50) having a full 0.5 W power rating.

This low cost, highly reliability carbon film resistor, is suitable for use in most types of circuits, including audio and communications as well as measurement and computer applications.

CFR Series are available in 5 power ratings from 1 ohm to 10 Mohm.
The smallest case size (CFR16) has a full 0.25 W power rating
The low cost, combined with high reliability, make these components suitable for use in most types of circuits, including audio, communications, measurement and computer applications

A comprehensive range of high stability carbon film resistors qualified and tested to the requirements of IEC 115 and IEC 115-2. The ruggedised welded cap and lead method of manufacture provides a considerable strength and resistance to damage. The coating materials and the colour bands are epoxy resin and are highly resistant to solvents, abrasion and chipping. Improvements in materials and processing have allowed the rated power to be improved. Excellent stability against changes in load conditions or moisture levels, with a low noise level and high reliability make these carbon film resistors suitable for a wide range of applications. Rated at 70°C in free air mounted horizontally. Climatic category 55/155/56.
