Introduction

RNC55J4752BSRSL is a through hole resistor type. Its features, applications and working principle will be discussed in the following text.

Features

RNC55J4752BSRSL is rated for 10W +/-5% per resistor and is sold in three different resistances: 100K, 250K, and 500K Ohms. It is a standard size device with an overall length and width of 0.95" x 0.4" (24.13 mm x 10.16 mm). The device features two contact leads that are 0.08" (2.03 mm) in diameter and spaced on 0.74" (18.8 mm) centers. As these are through-hole components, it is designed to be soldered directly to the printed circuit board. It features overvoltage rating of 800V and a maximum operating temperature of 125°C.

Application Field

RNC55J4752BSRSL is commonly used in applications such as automotive electrical systems, lighting and AC circuits, in addition to high-frequency resonator circuits. It can also be used in communications systems as fuses, signal conditioning, and other applications where resistance and power dissipation ratings are important. The device is suitable for corrosive or high vibration environments as the robust design will withstand such hostile conditions.

Working Principle

The RNC55J4752BSRSL is designed to limit the flow of electrical current in a circuit and is calibrated to have a specific resistance. The device works by introducing a resistance in series with the circuit which dissipates a portion of the electrical energy and can be used to control the flow of current in the circuit. This energy is dissipated as heat in the form of resistive losses. The device also benefits from a low temperature coefficient of resistance which will help to maintain stability as the device heats up due to the circuit operating conditions. It also benefits from a high resistance to power ratio which allows the device to be used in applications with higher wattage outputs such as AC circuits.

Conclusion

In conclusion, the RNC55J4752BSRSL through hole resistor is a reliable device well suited for applications requiring high power ratings and temperature stability. It is suitable for AC circuits, high frequency resonator circuits and communications systems. The device features two contact leads and a robust design which makes it suitable for challenging environmental conditions.
