Through Hole Resistors are one of the most common components found in electronics. In many cases, they are necessary for successful operation of an electric circuit, providing protection, reliability, and accuracy throughout a system. The RNC55H9421BSRE6 is a through hole resistor with an established application field and a simple yet effective working principle.

The RNC55H9421BSRE6 resistor is an axial-lead resistor, which means it can mount through the circuit board and provide better heat dissipation than other types. This makes it an ideal choice for high wattage, high-dissipation applications, such as power supplies and other power-critical systems. It has an operating temperature range of –55°C to +125°C and can handle up to 2W of power before needing to be de-rated. The RNC55H9421BSRE6 offers extremely low resistance levels, from 0.5Ω to 10MΩ, making it suitable for precision circuits where low resistance is essential.

In terms of construction, the RNC55H9421BSRE6 is made of a resistive material, such as carbon, which is shaped into a form and clamped between two pieces of wire. The wire is sealed in epoxy to ensure the electrical connection is completely protected against damage and corrosion. This construction ensures the resistor can maintain its integrity in high-temperature and hostile environments. The resistor also has integrated protection against transient over-voltages, which can occur in high-frequency circuits, making it suitable for use in oscillators and switching applications.

The working principle of the RNC55H9421BSRE6 resistor is straightforward yet effective. When a voltage is applied across the resistor, it causes a small current to flow through it. This current creates an opposing voltage, which is proportional to the amount of current flowing through it. This opposing voltage reduces the effective voltage across the resistor, so the resistor is able to resist a given amount of current, and the voltage is held to a predetermined level. This simple working principle has enabled the resistor to be used in a wide range of electronic systems and appliances.

The RNC55H9421BSRE6 is an ideal choice for the through-hole resistor market. Its robust construction and operating parameters make it a reliable choice for a variety of different circuits and applications. The wide range of available resistance levels combined with its simple working principle make it suitable for precision applications as well as more robust systems.
