Through Hole Resistors are indispensable components in many electronic systems, providing essential electrical resistance for circuit designs. The H816R2BDA is an example of such devices and is part of the range of resistors manufactured by Panasonic. Here, we explore its application and working principle.

Specifications of the H816R2BDA

The H816R2BDA resistor is a through-hole resistor with a case size of 8 x 16mm (where the first number represents the length and the second the width). It has an operating range of −55 to +125°C and a resistance range from 10Ω to 4.7MΩ, with a tolerance of ±5%. Input voltage is 200VAC.

Application of the H816R2BDA

The resistor is suited to a wide variety of applications, including power supplies, electronic test equipment and home appliances. It is suitable for use in low-temperature applications such as medical equipment and communication systems. With its small size, it is often used in applications with a limited board space.

The H816R2BDA provides the necessary electrical resistance but also gives off very little heat. This is due to its low temperature coefficient of resistance, meaning it can be used in applications where heat dissipation is critical. This makes this resistor especially suitable for use in high-frequency, high-current circuits where there is little tolerance for heat.

Working Principle of the H816R2BDA

At the heart of the H816R2BDA is a metal oxide film, which is deposited on the resistor’s contact substrate. This layer acts as a resistor, providing precise resistance values according to the required applications. As current passes through the resistor, a voltage drop is produced, allowing for the precise control of current.

The H816R2BDA also features a wire-wound structure, which helps the resistor cope with high surges of current and temperatures. The wire-wound layers are insulated with a ceramic-like material which helps protect the resistor from heat while allowing for a higher power rating.

The H816R2BDA has a curved-shape contact substrate design, which provides better thermal characteristics. A higher surface area with fewer materials also helps to reduce temperatures, making the device well-suited to high power applications.

Conclusion

The H816R2BDA is a through-hole resistor which is suitable for a wide range of applications. It has a case size of 8 x 16mm and operates in a temperature range of −55 to +125°C. Its resistance range is 10Ω to 4.7MΩ and it provides precise resistance through a metal oxide film and wire-wound layers. Furthermore, its curved-shape contact substrate design helps to reduce temperature, making it ideal for high-power applications.
