TY Fuse Resistor

Classification Introduction of Fuse Resistors

Fuse resistors are resistors with special properties. They can function as resistors in a circuit and also act as fuses to protect the circuit under specific conditions. Here is an introduction to various types of fuse resistors:

1. RXF21 - TE Power - Type Full - Short - Circuit Thermal Fuse Resistor

• It belongs to the power - type resistor and can withstand a large power load.

• It has a full - short - circuit function. When the temperature reaches a certain value, the resistor will quickly short - circuit, cutting off the circuit and providing protection.

• It is often used in circuits that are sensitive to temperature and require high - power protection, such as power supply circuits and power amplifiers.

1. RXG21(A/B/C/D) Lightning - Surge - Resistant Wire - Wound Resistor

• It adopts a wire - wound structure and has high accuracy and stability.

• Its key feature is its ability to resist lightning surges and can withstand instant high - voltage and high - current impacts.

• Different models of A, B, C, and D may vary in resistance range, power, and surge - resistance capabilities. It is widely used in power systems, communication equipment, and other circuits vulnerable to lightning surges.

1. RWF Molded - Wire - Wound Fuse Resistor

• It combines the molding process and wire - winding technology, endowing the resistor with good mechanical and electrical properties.

• When the current or temperature in the circuit exceeds a certain limit, it can quickly fuse and cut off the circuit.

• It is suitable for some circuits with high requirements for the reliability and stability of resistors, such as industrial control circuits and automotive electronic circuits.

1. RF11 Ceramic - Cased Thin - Film Fuse Resistor

• It uses a ceramic case as the substrate and is coated with a thin - film resistance material on the surface, having good insulation and heat - dissipation properties.

• The thin - film structure gives the resistor high accuracy and a small volume, and its fusing characteristics are relatively sensitive.

• It is often used in some electronic devices with high requirements for space and strict requirements for accuracy, such as digital products and instruments.

1. RF10 Painted Thin - Film Fuse Resistor

• Similar to RF11, it is also a thin - film fuse resistor, but it is encapsulated using a painting process.

• The paint layer can protect the resistor from the influence of the external environment and also has certain insulation and heat - dissipation properties.

• It is generally applied to ordinary electronic circuits, such as consumer electronics products and lighting circuits.

1. MZ60 Metal - Film Thermistor

• It belongs to a type of thermistor and works based on the property that the resistance value of the metal film changes with temperature.

• It has high sensitivity and a fast response speed and can adjust the resistance value in a timely manner according to temperature changes.

• It can be used in temperature - measuring, temperature - controlling, and over - temperature protection circuits, such as the temperature control systems of household appliances like air conditioners and refrigerators.

1. RXF21 - D Half - Short - Circuit Surge - Resistant Wire - Wound Resistor

• It is a wire - wound resistor with a half - short - circuit function and can withstand the impact of surge current to a certain extent.

• Different from the full - short - circuit resistor, the half - short - circuit surge - resistant wire - wound resistor does not completely short - circuit when a fault occurs. Instead, it limits the current through a special structure and materials to protect the circuit.

• It is suitable for some circuits that have a certain tolerance to surge current but do not want a full - short - circuit situation, such as some communication power supply circuits.

1. RXF21 - T Small - Power Full - Short - Circuit Thermal Fuse Resistor

• Its main features are small power and full - short - circuit thermal fuse function.

• It has a small volume and is suitable for small - scale circuits with low power requirements but in need of temperature protection.

• When the temperature rises abnormally, it will quickly short - circuit completely, cutting off the circuit and protecting other components from damage. It is often used in the circuit boards of small electronic devices.

1. RXF21A/B/C(FRT) Wire - Wound Fuse Resistor

• It adopts a wire - wound structure and has high power - handling capacity and stability.

• Different models of A, B, and C may differ in resistance value, power, and fusing characteristics to meet the needs of different circuits.

• It is widely used in various electronic circuits, especially in occasions with high requirements for the reliability and fusing performance of resistors, such as power supply circuits and motor control circuits.
