Through hole resistors are one of the main components in electronics applications. The H4953RBZA is a series of through-hole resistors manufactured by Schaffner and distributed by Ohmite. It is designed for a wide range of applications requiring tight tolerances, low temperature and stable performance.

The four main characteristics that make the H4953RBZA ideal for a variety of applications include small size, low heat dissipation, low-temperature stability, and excellent temperature cycle stability. Its size and weight are only 0.75 x 0.5 inches and 1.71 oz. respectively, making it an ideal choice for embedded systems.

These resistors are designed to operate in temperatures ranging from -55 to +125 degrees Celsius, making them suitable for use in both hot and cold environments. They also have an excellent temperature-cyclability, which further enhances their overall efficiency. In addition, they feature superior electrical performance, with a wide type range that includes one ohm to two megohms of resistance.

Regarding their working principle, a high voltage is applied to the resistor, and the current flows through it based on its resistance value. This causes a drop in the voltage across the resistor which can be used to measure the current, providing further accuracy. As the current increases, the power dissipation within the resistor increases and it becomes hot, causing the temperature to rise. Therefore, the H4953RBZA is designed with a low heat dissipation capacity to provide long-term operating stability.

The H4953RBZA series of through-hole resistors are highly suitable for a variety of applications. They are used in process control systems, as well as in other circuits such as power distribution, transformer, audio, and optical fiber networks. Additionally, they can be found in automotive and industrial control systems, radio frequency and satellite communication systems. They are also used in thermoelectric cooling devices, which are used in medical and aerospace industries.

Because of its small size, low heat dissipation, low-temperature stability, and excellent temperature cycle stability, the H4953RBZA series of through-hole resistors is an ideal choice for a wide range of applications. It is a reliable and dependable component, and is available in a variety of resistance values to suit different applications.
