Through Hole Resistors, or THR, are resistors which are designed and manufactured to fit directly into an electronic circuit board. They are also known as “through-the-air” resistors and are typically rectangular in shape. The most common through hole resistor is the H820R5DYA. This resistor is designed for use in automotive, consumer and industrial applications, and its working principle is straightforward.

The H820R5DYA is composed of two parts: a lead frame and a comb-like resistor wire. The lead frame is a flat metallic substrate with contacts that provide an electrical connection to the circuit board. The inclining comb-like resistor wire is located in the center of the lead frame. This resistor wire is composed of insulated coils, which make up the resistance. The contact points on the resistor wire are connected to the pins of the lead frame. When a current is applied to the pins, a voltage across the resistor wire creates a current through the wire, and the resistance level of the wire determines the amount of current that flows.

One of the benefits of using through hole resistors is that the components are already enclosed in a physical frame, meaning that the circuit board does not have to be manually manipulated in order to mount the resistor. This makes the assembly process much faster and more efficient. In addition, through hole resistors have consistent and reliable performance, since all of the components are fully enclosed and protected.

The H820R5DYA is ideal for applications with low power ratings and low voltages. They are frequently used in automotive, consumer, and industrial applications, such as audio systems, lighting fixtures, and instrumentation. They are also commonly used in applications that require high resistance accuracy, such as alarms, temperature sensors, and medical equipment.

The H820R5DYA is extremely reliable and capable of withstanding temperatures up to 150°C. It is also resistant to corrosion, and is UL approved for safety and reliability. The resistor is available in various sizes, shapes, and resistance values, making it a versatile component for a wide variety of applications. It is also a cost-effective solution due to its low cost and minimal required maintenance.

In summary, the H820R5DYA is a through hole resistor that is designed for use in automotive, consumer, and industrial applications. It is composed of a lead frame and a comb-like resistor wire, which provide consistent and reliable performance. The resistor is ideal for low-voltage, low-power applications, and can withstand temperatures up to 150°C. It is available in various sizes and shapes, making it a versatile and cost-effective solution for a wide variety of applications.
