Through Hole Resistors: RN55D2503FB14 Application Field and Working PrincipleThrough-hole resistors, commonly known as subject resistors, are found in a wide variety of applications. From consumer electronics products to industrial and military applications, they are widely used for the purpose of electrical current regulation. The RN55D2503FB14 is a through-hole resistor of size 0603 and package size 0603. It is constructed from a copper stripe on a cylindrical ceramic base. It offers a resistance of 2503Ω and precision of ±10%. This resistor is capable of providing excellent thermal resistance and is well suited for use in electrical equipment that require long life and reliability. Its application field includes telecommunications, military, medical, networking and home appliances.In terms of working principle, the resistance of a through-hole resistor is defined by the electric resistance of the copper strip which is wrapped around the ceramic base. This copper strip interacts with the ceramic base, which provides a high-quality electrical insulation between the two contacts of the resistor. This ensures high reliability and stability of the resistor.In addition, the resistance is also determined by the ratio of the length to width of the copper strip. Apart from this, the amount of air gap between the ceramic base and the copper strip determines the resistance of the resistor. A bigger air gap will provide lower resistance, while a smaller air gap will provide higher resistance.The temperature coefficient of resistance (TCR) of the RN55D2503FB14 is specified at ±30 ppm/°C and Load Life Stability at ±15%. Moreover, the resistor offers excellent high frequency characteristics, low volatility, and low leakage. It is designed for operating temperature range of -55°C to +125°C and is available in RoHS compliant options.Overall, the RN55D2503FB14 through-hole resistor is an excellent choice for applications that require long-term stability, reliability and accuracy. It is a preferred option for power supplies, power amplifiers, switch mode power supplies, and a wide range of other applications.
