Through Hole Resistors are a vital element in the functioning of nearly any electronic device or circuit. This includes any device that involves the movement of electrons, from televisions to computers to cell phones. The main purpose of through hole resistors is to control the electrical current and voltage passing through a circuit. They do this by limiting the amount of current that flows through the circuit and giving the circuit the protection it needs from electrical overstress or thermal stress. One of the most common through hole resistors is the RN55C1284BB14, and this article will discuss the features and applications of this resistor, as well as its working principle.

Features of the RN55C1284BB14

The RN55C1284BB14 is a surface mount chip resistor available in a 1206 package. It is a thin film resistor with a resistance value of 1.2KΩ ± 5% tolerance. Its power rating is 1/16 watt at + 70°C. It features a maximum working voltage rating of 200 Volts. The RN55C1284BB14 has a dissipation factor of 0.3, and a surge voltage rating of 220 Volts. It has a temperature coefficient of -10 to +50 ppm/°C, and a dielectric strength of 1500 Volts. The RN55C1284BB14 is AEC-Q200 qualified and halogen free, making it a reliable choice for use in automotive applications.

Applications of the RN55C1284BB14

The RN55C1284BB14 is suitable for a variety of applications, such as power management circuits, switching regulators, DC-DC converters, and other electronic circuits. It can also be used in automotive electronics, such as airbag deployment systems, dashboard displays, and navigation systems. Due to its reliable performance and AEC-Q200 qualification, the RN55C1284BB14 is particularly well-suited for automotive applications.

Working Principle of the RN55C1284BB14

The RN55C1284BB14 works by controlling the flow of current within a device or circuit. It does this by using a resistive material, such as metal oxide, to increase the amount of resistance in the circuit. This decrease in current helps to protect the device or circuit from electrical overstress and thermal stress. When current passes through the resistor, it produces heat, which increases the temperature of the circuit. This can be prevented by using the RN55C1284BB14, as its temperature coefficient is -10 to +50ppm/°C, meaning it won’t produce as much heat as other resistors.

Conclusion

The RN55C1284BB14 is a versatile and reliable through hole resistor that is ideal for use in many electronics applications, especially in automotive electronics. Its features, such as AEC-Q200 qualification, halogen free construction, and low temperature coefficient, make it a great choice for use in devices and circuits that require protection from electrical overstress or thermal stress. Hopefully this article has given you a better understanding of the RN55C1284BB14 and the many applications it can be used for.
