Through Hole Resistors are essential components in various electrical circuits and systems. They play a critical role in maintaining steady current and voltage levels in all application fields. The HHV1WSJR-73-20MY resistor is a leading through hole resistor device used in many applications. Read on to learn about its properties, working principle, and application field.

Overview

The HHV1WSJR-73-20MY is a through hole resistor that is widely used in the electrical engineering field. It is a three-pin resistor with the standard size of 120 mils, and comes with a resistor value of 20MΩ. It is commonly known as an \'ultra-high resistance\' resistor because of its very high resistance value. The resistor is composed of three different resistive elements, each one calibrated to a distinct exact value.

The electrical element has a three-pin construction, with pins lying in a 120°C pattern. The first pin is connected to the cathode and the third pin is connected to the anode. The package of the resistor is steel and features a standard case shape.

Working Principle

The resistance of the HHV1WSJR-73-20MY resistor is created through its construction. Its three resistive elements are constructed with metal foil strips having a certain spacing between them, which helps to achieve the desired resistance value of 20MΩ. The resistor is a non-linear device; meaning that its resistance does not remain exactly the same even as the voltage across it remains constant. It experiences thermal drift, in which its resistance value increases as the temperature increases.

The resistor also relies on its construction to ensure excellent frequency characteristics. The resistor\'s very low thermal capacitance ensures that even with sudden changes in voltage, it can remain stable. It also has a very low voltage noise level and a very short rise time. This helps maximize the reliability and stability of the resistor.
