Through Hole Resistors: H4137KBZA Application Field and Working Principle

Through hole resistors, also known as leads, are passive components commonly used in a variety of electronic circuits. The H4137KBZA through hole resistor is one of the most popular components for prototyping and production circuits due to its robust construction, multiple mounting and configuration options, large tollerance range, and low cost. In this article, we’ll explore the application fields and working principles of the H4137KBZA.

What is a Through Hole Resistor?

A through hole resistor is a passive electronic component consisting of a resistor with two pins that pass through the component body. As the name implies, these pins are inserted into through holes in the circuit board, and the component is secured to the board with a mounting clip. The H4137KBZA is a ceramic-encased through hole resistor that is rated 3/4 watt up to 250 volts.

Application Field

The H4137KBZA is suitable for a variety of through hole applications and can be used in both analog and digital circuits. It is commonly used in voltage and current dividers, voltage drops, signal conditioning circuits, and even signal correction. Its robust construction and large tolerance range make it an ideal choice for prototyping and production circuits.

Specifications:

Type: Through Hole Resistor
Size: 12mm x 6.8mm
Terminals: Through hole pins
Tolerance: 5%
Rated Power: 3/4 watt
Voltage Rating: 250 volts
Operating Temperature: -55°C to 150°C

Working Principle

The H4137KBZA works by creating a resistance between the two terminals when an electrical current passes through it. As electrical current passes through the resistor, some of the energy is converted into heat, which dissipates into the environment. This principle of resistance is known as Ohm\'s Law. Once the component is securely mounted to the circuit board, the current flowing through the circuit can be adjusted by varying the resistance between the two pins.

Conclusion

The H4137KBZA through hole resistor is a robust component that offers multiple mounting and configuration options as well as a large tolerance range. It is ideal for prototyping and production circuits alike, and can be used in a variety of applications ranging from voltage and current dividers to signal conditioning.
