Through hole resistors are used to limit current as well as maintain a set voltage in an electronic circuit. They are typically used in circuit boards and electronic components, although they can be used in many other applications. The H82K21BZA is a type of through hole resistor designed specifically for the automotive and commercial/industrial industries. It is a durable and reliable resistor that has a wide range of uses.

The H82K21BZA is a high voltage, high resistance, through hole resistor with a power rating of up to 21W and a maximum voltage rating of 750V. This resistor is capable of withstanding high voltage and current surges without any damage or degradation. It also features a low temperature coefficient, making it an ideal resistor for temperature-critical applications. The resistor is designed to have a low inductance, allowing it to be used in high-speed digital applications.

The H82K21BZA is constructed with a body made of ceramic and a metal cap on one end. The ceramic body helps to provide extra protection and insulation from outside elements. The metal cap is designed to dissipate heat efficiently and protect the resistor from excessive heat buildup due to loads. The resistor is also protected by a thin sheath of polycarbonate, which helps to protect it from mechanical shock and vibration.

The H82K21BZA is designed for use in a variety of applications, including power supplies, consumer electronics, telecommunications, automotive, and commercial/industrial applications. It can be used in circuits as the primary source of current limit or voltage drop, or as an additional series resistor for current sensing or voltage control. It is also commonly used in circuits as a feedback resistor, voltage divider, or as protection against voltage transients.

The H82K21BZA operates on the principle of Ohm’s Law, which states that the current passing through a resistor is proportional to the voltage applied across it. As the voltage increases, the current passing through the resistor increases proportionately. This principle is used in all types of resistors, including the H82K21BZA, to control voltage and current levels in circuits.

The H82K21BZA also features a long-term reliable construction, which ensures reliable operation even under extreme temperatures and high-amplitude electrical pulses. This makes it an ideal choice for automotive and industrial applications, where continuous reliable operation is required. The durable construction also makes it a suitable choice for applications that may require frequent maintenance, such as motor controls, telecoms, medical equipment, and power supplies.

In summary, the H82K21BZA is a through hole resistor designed specifically for industrial and automotive applications. It features a high voltage rating, a low temperature coefficient, and a high resistance, making it suitable for a wide range of applications. It works on the principle of Ohm’s Law, and the construction ensures a reliable performance even under extreme temperatures and electrical pulses. The resistor is a durable and reliable choice for circuit boards, electronic components, and other applications.
