Through Hole Resistors are indispensable components in modern electronics. They form the backbone of circuits, providing the necessary resistance needed for proper function. The RN55E4221FB14 is a high quality through hole resistor manufactured by ON Semiconductors and is widely used in a variety of applications. This article will discuss the application fields of the RN55E4221FB14, as well as its working principle.

The RN55E4221FB14 is primarily used in audio, video processing, and amplifier applications as it can provide superior performance at an economical cost. Its additional benefits include a high operating temperature range (from -55°C to +150°C) and excellent tolerance of only ±1%. These characteristics make the RN55E4221FB14 the perfect choice for applications where precise resistor values and long-term reliability are needed.

The high heat dissipation performance of the RN55E4221FB14 also makes it suitable for power dissipative components. Its power rating can exceed 1W (depending on the design) while maintaining a maximum temperature rise of less than 25°C. This ensures that the components remain thermally stable even under high dissipative conditions, providing the user with maximum performance and reliability.

The RN55E4221FB14 is also commonly used in pulse applications due to its high-speed switching capability. The device has fast switching times and can handle pulse widths of up to 20µs. This makes it ideal for any application requiring fast or high-speed switching.

The working principle behind the RN55E4221FB14 is relatively simple. When a voltage is applied across the resistor, the resistance within it creates a voltage drop across the unit. This voltage drop is equal to the applied voltage multiplied by the resistance. The amount of voltage drop will depend on the value of the resistor, so the higher the resistance, the more voltage will be dropped. The amount of current flowing through the resistor will also depend on the resistance, so the higher the resistance, the less current will flow.

In order to achieve the high performance and stability of the RN55E4221FB14, the resistor is manufactured to very precise tolerances. The tolerance also determines the amount of variation in the resistor’s resistance value. For example, if a resistor has a tolerance of ±1%, that means that the actual resistance of the resistor could be as much as ±1% from the nominal value. To ensure precise performance, the production process of the RN55E4221FB14 is closely monitored and all manufacturing batches are regularly tested to ensure that they meet the high standards expected.

The RN55E4221FB14 is a high-performance through hole resistor that is ideal for audio, video processing, amplifier circuits, power dissipative components, and pulse applications. Thanks to its precise tolerances, high operating temperature range, fast switching times and excellent power handling capacity, the RN55E4221FB14 is the perfect choice for these applications. The working principle behind the RN55E4221FB14 is also quite straightforward and the device is manufactured to very precise tolerances to ensure maximum performance and stability.
