Through Hole Resistors have a variety of application fields and they work on the basis of Ohm’s Law. They are extensively used in applications such as electrical circuit construction, DIY projects, scientific tests, electric motors, and electrical power systems. The resistor is usually made up of a metal or ceramic material, usually copper or aluminum, in which current flows through its terminals. One terminal of the resistor is connected to the circuit, while the other is connected to a grounded point. The amount of current flowing through the resistor is proportional to the voltage applied across its two terminals.

H81K21BCA resistors are through-hole resistors available in radial package, making them ideal components when mounting with through-hole applications. Their major application is in industrial, automotive, medical and mobile applications. H81K21BCA has a current rating of 23.1A (0.2watt) and a voltage rating of 21V. Its dielectric strength of 110V is suitable for numerous types of installations. Its tolerances are ±1%, ±1.6%, ±2%, ±2.3%, ±2.5%, ±2.8%. These resistors are available in four distinct footprint options- 0805, 1206, 1210, 2512.

H81K21BCA resistors work on the basis of Ohm’s law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. The resistor is a passive electronic component that operates under the law of Ohm and is used to regulate or limit the flow of electric current in an electrical circuit. It is used to reduce the current so as to protect other components from damage when an overload or short circuit occurs in the system. By inserting a resistor in the circuit, the voltage drop across the resistor creates a potential difference, resulting in a decrease in current flowing into the resistor.

These resistors are highly resistant to various environmental conditions such as extreme temperatures, UV radiation, moisture or humidity, dust, chemicals, and vibration. They also possess a high degree of thermal stability and stability of electrical characteristics. H81K21BCA resistors are available in a wide range of sizes and power ratings, making them suitable for virtually all types of application in various industries.

Because of their high current load, H81K21BCA resistors can be integrated in various applications requiring extremely low resistance values for high current applications and extremely high resistances for small current applications. The key components used in their construction are impregnated hexagonal ceramic cells, with their die-cast outer walls that are then further plated with a protective film. The advantages of using H81K21BCA resistors as against other types of resistors are their extremely high accuracy, performance, and reliability.

H81K21BCA resistors can be used in a variety of applications. They are often employed in automotive, medical, and military applications requiring high current and high voltage resistance. They can also be used as power supplies, load switches, anti-static protection, lightning protection, etc., as well as in power line and signal line noise suppression components, withstanding high inrush and lightning strike resistance. Generally, H81K21BCA resistors are highly efficient and cost-effective, making them suitable for various applications.
