Through hole resistors have a range of applications and are an important component in electrical circuitry. The symbolic representation of a resistor is the letter R with the number of the resistance beside it. Resistors are typically used to limit and control the flow of current in a circuit, and they come in a range of sizes, resistance ratings, and tolerances. This article will provide an overview of the H811R8BCA resistor type and explain its working principle.

Description of the H811R8BCA Resistance

The H811R8BCA is a 1 watt metal film resistor, designed to reduce levels of current in circuits. The resistance rating of this part is 470 ohms, with a tolerance rating of 2%, meaning that when this resistor is installed correctly, the received current through it should be within 2% of the resistance rating. Unlike other resistor types, the H811R8BCA has a low temperature coefficient, making it suitable for using in high-temperature environments. Its maximum working voltage is 450V, making it an ideal choice for many applications that require high voltage resistance.

Types of Applications of the H811R8BCA Resistor

The H811R8BCA can be used in a range of applications that require high voltage resistance, such as power supplies, amplifiers, and voltage-controlled oscillators. It is also suitable for use as part of a voltage divider or as a feedback decoupling circuit, as it provides a stable and reliable voltage source, even under thermal stress. Other applications for the H811R8BCA include electric motor and solenoid control and as part of timer circuits.

Working Principle of the H811R8BCA Resistor

The H811R8BCA works by reducing the amount of current that passes through a circuit. When power is applied to the resistor, electrons flow through it and are stopped by its resistance. The current passing through the resistor is determined by the voltage applied to it and the resistance rating, which can be calculated using Ohm\'s Law (V = I x R, where V is the voltage, I is the current, and R is the resistance).

The H811R8BCA is designed to have a low thermal coefficient, meaning it will remain stable and not overheat quickly. This makes it suitable for use in circuits where high current may be drawn. It is also designed with an epoxy coating, which helps to protect the resistor from environmental damage.

Conclusion

The H811R8BCA metal film resistor is a 1 watt resistor with a 470 ohm resistance rating and a 2% tolerance. It is an ideal choice for applications that require high voltage resistance, such as power supplies, amplifiers, and voltage-controlled oscillators. It has a low thermal coefficient, making it suitable for use in high-temperature environments and it is protected from environmental damage with a layer of epoxy coating.
