Through Hole Resistors, such as the H4442KBZA model, are widely used in the fields of medical instruments and aerospace applications. The H4442KBZA, especially, has come to be known as a reliable and affordable resistor ideal for high-performance applications. It is an axial-lead resistor, with a two-letter suffix indicating its power rating. The axial leads are made of tin-plated steel and the resistor material is carbon-film.

The H4442KBZA model is extremely versatile and can be utilized in a variety of applications, as long as the correct parameters are chosen. It is designed with a high working temperature range of -55°C ~ +155°C, making it suitable for many extreme environments. Its excellent mechanical toughness also provides superior reliability. This makes it ideal for applications such as medical instrumentation, home appliances, power supplies, and aerospace applications.

The H4442KBZA operates in a simple resistive-divider circuit, utilizing a four-terminal network. In this network, there is a voltage divider between the two end terminals, with the fourth terminal in the middle providing the reference potential. The resistor\'s value is determined by the ratio of the resistance between the two outer terminals to the resistance between the two inner terminals. This ratio is referred to as the "Ratio of Two Resistors," or R2R.

The H4442KBZA is also designed to provide excellent precision, with a tolerance of ± 5%. Its temperature coefficient of resistance (TCR) is also quite low, at ± 50ppm/°C. This ensures a consistent performance even when operating with high temperatures. The dual-service capabilities of the H4442KBZA also make it a good choice for applications that require both AC and DC performance.

Overall, the H4442KBZA model is designed to offer reliable, dependable, and precise performance in a variety of applications. Its four-terminal design and precise tolerances make it suitable for both industrial and aerospace applications, and its temperature and electrical characteristics ensure consistent performance in extreme temperatures and environments. This makes it an ideal choice for many high-performance applications, especially in the medical and aerospace sectors.
