Through Hole Resistors are the most preferred type of resistors used in circuit boards. This is due to its low resistance value, low cost and easy maintenance. The RWR78S3321FMB12 is a Through Hole Resistor which is widely used in many applications. This article looks at the application field and working principle of the RWR78S3321FMB12.
Application fieldThe RWR78S3321FMB12 is a Through Hole Resistor developed primarily for use as a voltage divider, current limiter, and voltage regulator. It is compatible with high and low DC power supply applications and is suitable for controlling AC loads and motors. Due to its wide operating temperature range and high heat dissipation, it is also suitable for high power applications.
Working Principle The working principle of the RWR78S3321FMB12 is based on Ohm’s law and is one of the most reliable and stable resistors. It works by providing a barrier between two points in an electronic circuit which works to reduce current flow. This is achieved by creating a voltage drop across the resistor, which in turn controls the current passing through the circuit by limiting resistive, develop reducing, and reactive power loss.
The main parameters of the RWR78S3321FMB12 are its rated voltage, rated power, operating temperature, and mechanical parameters, such as size and weight. The rated voltage of this resistor is 25V, the rated power is 6W, and the operating temperature is -25°C - +85°C. The RWR78S3321FMB12 has a small size of 57.3*24.3mm and a lightweight of 17.5g.
Due to its reliable and stable performance, the RWR78S3321FMB12 is widely used in many fields like automotive, communications, power control, and LED displays. Specifically, it is used in AC power flows, DC surge current protection, air conditioning control units, mobiles, energy saving lamps, and other voltage regulating systems.
In conclusion, the RWR78S3321FMB12 is a Through Hole Resistor which is widely used in various applications thanks to its reliable and stable performance. Although it is mainly used as a voltage divider, current limiter, and voltage regulator, it is also suitable for controlling AC loads and motors. Therefore, this type of resistor is an indispensable part of electronic products and tools.
