Through Hole Resistors – FRN25J33R Application Field and Working Principle

Through hole resistors play a huge role in electronic circuits. These devices are commonly used to limit current, to divide voltages, and also to stabilize electrical signals. The FRN25J33R is the most commonly used through-hole resistor. It has a broad range of applications in electronics, and it is widely available in the market. It is used for various types of digital and analog applications, including motor control, LED lighting, switching power supplies, and many others.

What is the FRN25J33R?

The FRN25J33R is an axial, through-hole resistor with a power rating of 25 Watts. It has a low temperature coefficient of 40ppm/degC and can handle °C operating temperatures ranging from -55 to +125°C. The FRN25J33R has a tolerance of 5% and is resistant to over-voltage, producing minimal ringing when used in circuits. It also has an adequate voltage handling capacity, exhibiting good frequency performance.The FRN25J33R is composed of two parts, the wirewound and the substrate. The substrate is made of either alumina or ceramic materials and the wirewound is usually composed of the most common alloys, such as nickel, iron, copper, and zinc. Device features can be customized by making adjustments to the substrate material. Furthermore, the device is equipped with a coated interior and can be fit into small, tight spaces.

Application Field of The FRN25J33R

The FRN25J33R has a wide range of applications. Some of these applications include:

• DC to DC voltage regulators;
• Power amplifiers;
• LED lighting control;
• Dimming circuits;
• Navigation systems;
• Power supply surge protectors

• Variable frequency drives;
• Motor control;
• Solenoid activators; and
• Power generation systems.

Working Principle of the FRN25J33R

The FRN25J33R works in a simple manner. It is composed of two parts, the substrate and the wirewound, and these two parts are joined together to form the device. The wirewound is typically composed of an alloy of nickel, iron, copper, or zinc, and the substrate is usually made of alumina or ceramic material.When a current flows through the FRN25J33R, the wirewound element will heat up and expand within the substrate material. This expansion increases the resistor\'s value and reduces its resistance. The device will dissipate the heat as heat energy and the resistance will be maintained.The FRN25J33R is designed to regulate current and voltage at the same time. It is able to handle a wide range of voltages while remaining stable, without producing any ringing or impedance shift. The device also has a tolerance of 5% and can handle temperatures ranging from -55 to +125°C.

Conclusion

The FRN25J33R is an axial, through-hole resistor with a power rating of 25 Watts. It has a low temperature coefficient of 40ppm/degC and can handle °C operating temperatures ranging from -55 to +125°C. This device has many applications, including motor control, LED lighting, switching power supplies, navigation systems, and many more. Its construction, composed of a substrate and a wirewound part, enables it to regulate current and voltage simultaneously without producing noise or ringing. The FRN25J33R is an effective device for controlling electrical signals and should be considered for any type of electronic application.
