Introduction

Through hole resistors, which are also known as ‘axial resistors’, are a type of passive electronic component used to measure and control the flow of electric current. The basic purpose of through hole resistors is to reduce current flow and/or add resistance to an electrical circuit. Through hole resistors are typically made out of carbon film, metal film, and thick film resistors. CFR50SJT-52-390K is one of the most popular through hole resistors used in the market.

CFR50SJT-52-390K application field and working principle

The CFR50SJT-52-390K is a fixed carbon film resistor that provides resistor values from 50 to 390 kilo-ohm (KΩ). It is a through hole resistor constructed around an epoxy coated metal body. The element of the CFR50SJT-52-390K is a carbon film which typically has an operating temperature range between -55°C and 150°C. It has a power rating of 2 W and a tolerance of 5% or 10%.The CFR50SJT-52-390K is mainly used in the electrical and electronics fields, such as telecommunications, instrumentation, and audio systems. Its main job is to decrease the magnitude of current or just control the desired operational current within bounds. Additionally, it is also used in pulse, voltage-stabilizing, filter, audio amplifier, and bridge rectifier circuits. The working principle behind the CFR50SJT-52-390K is relatively simple but effective. The resistance element is created by winding layers of synthetic carbon film around a substance like a ceramic tube or a fiberglass core. This breaks up any possible direct paths of current flow inside the resistor. This is what makes CFR50SJT-52-390K effective at reducing the overall current flow in various circuits.

Advantages of CFR50SJT-52-390K

There are many advantages to using the CFR50SJT-52-390K as an electrical and electronics component. It has a wide range of operating temperatures, a relatively small size, and a low self-inductance. Additionally, the CFR50SJT-52-390K has excellent noise capability, good temperature coefficient of resistance, and high stability even when operating at a higher temperature.

Conclusion

The CFR50SJT-52-390K through hole resistor is a great device to use in circuits needing electrical and electronics components. Its wide temperature range, low self-inductance, and small size make it a top choice for many applications. By using the CFR50SJT-52-390K, engineers and technicians can effectively control current flow in their circuits without compromising other components.
