Through Hole Resistors: H440R2BZA Application Field and Working Principle

Through hole resistors are used widely in numerous electrical and electronic circuit applications. The H440R2BZA is a 4-terminal (4T) carbon film resistor with low thermal resistance and a flame-retardant housing, and is designed mainly for use in high voltage and power applications.

Overview of Through Hole Resistors

Through hole resistors gain their name from the way they are secured to a printed circuit board (PCB). This involves mounting them to a through hole where a pin is inserted on one side and the connection is made on the other. This increases the component’s stability, simplifies the soldering process, and eliminates the need for other soldering techniques, such as wave soldering. Another benefit of through-hole mounting is the high isolation output that it provides.Through hole resistors are generally composed of a wire or a printed conductive pattern that surrounds a substrate material that is primarily composed of a ceramic material called alumina. When the ceramic substrate is fired, the wire or printed conductive pattern is made permanently into a resistor pattern. Substrates are fired in an oven at a temperatures ranging from between between 900 and 1400°C. The resistor elements are composed of a metal, such as nickel, which is metallized onto the heated alumina substrate. This process results in a resistor that is mechanically robust and has a high degree of resistance to vibration, corrosion, and temperature extremes.

H440R2BZA Application Fields and Working Principle

The H440R2BZA is mainly designed for use in high voltage as well as power applications, where a high-power resistor with low thermal resistance is required. The H440R2BZA has a flame-resistant rating UL94V-O, and it offers excellent stability and reliability over a wide range of temperatures.Its working principle is based on Ohm\'s law, which states that the current flowing through a conductor is proportional to the potential difference (voltage) across its ends. The resistor restricts the flow of current by providing a lower path of resistance for the current to travel through. Thus, the resistor can be used to regulate the voltage, current, or power within an electronic circuit.The H440R2BZA features an axial lead construction, which enables it to be easily mounted to a printed circuit board. It is also available in a variety of tolerance ratings and power ratings, making it suitable for a wide range of applications. Additionally, its low thermal resistance ensures that the resistor dissipates heat effectively, making it ideal for use in high-power and high-voltage applications.

Conclusion

Through hole resistors such as the H440R2BZA provide effective and reliable circuit protection in numerous electrical and electronic systems. This 4-terminal carbon film resistor offers excellent stability and reliability over a wide range of temperatures, making it ideal for high voltage and power applications. Moreover, its axial lead construction ensures that it can be easily mounted on a printed circuit board, further improving its stability.
