Through Hole Resistors

Through hole resistors are electrical components used to control or limit electric currents. They are one of the most commonly used components in electrical and electronic circuits. The H81K3FDA is a through hole resistor with an operational temperature range of -50°C to 70°C and working voltage of 250V.

Application Field of H81K3FDA

The H81K3FDA is used in a wide range of applications such as power supplies, home appliances, audio-video equipment, lighting systems, and automotive and industrial control systems. It is used in motor drive systems, lighting control, and thermal overload protection. The component is suitable for any system design where reliable performance is required.

Working Principle

The working principle of the H81K3FDA is based on Ohm’s Law. When a voltage is applied to the resistor, a current is passed through it and a certain amount of heat is generated. The amount of heat generated depends on the magnitude of the voltage and the resistance of the resistor. The resistor will then dissipate this heat to its surroundings. The resistor has a high heat resistance, which allows it to handle higher power levels than other types of resistors. This is why it is often used in applications where temperature control is important.The H81K3FDA also has a power rating that determines the maximum power it can handle without sustaining damage. This rating should be kept in mind when selecting the resistor for a particular application.

Conclusion

The H81K3FDA is a versatile and reliable through hole resistor, suitable for a wide range of applications. Its high heat resistance and power rating make it a good choice for temperature sensitive and high power applications. It is important to keep in mind the operational temperature range, working voltage, and power rating of the resistor when designing circuits. By doing so, engineers can ensure that the component will provide reliable performance.
