Through Hole Resistors are components found in most electrical and electronic applications and play a critical role in regulating current flow. The HHV1WSJT-73-22M is a through-hole resistor that is effective in a range of use cases. This article will explain the HHV1WSJT-73-22M’s application fields and working principles.

General Description

The HHV1WSJT-73-22M is a through-hole resistor, which is designed similarly to a wire-wound resistor, consisting of a resistor element and a terminal-feeding collet. It contains a nickel-chromium alloy wire, a glass-filled polyvinylchloride (PVC) body, and a tin-plated solderable terminations. Its performance and specifications are in accordance with both IEC 60050-461 (International Electrotechnical Vocabulary) and IEC 60065 (Audio, Video and Similar Electronics Apparatus).

Types of Through-Hole Resistors

When discussing through-hole resistors, it is necessary to know the types that one can encounter when dealing with them. The pre-defined resistor ratings are categorized into banded resistors (RB series), hermetically sealed resistors (RS series), power rating resistors (RP series), and wire-wound resistors (RW series). The HHV1WSJT-73-22M belongs to the second category, hermetically sealed resistors.

Applications

The HHV1WSJT-73-22M is commonly used for low-power applications that require precise measurements of resistance values. Low-power applications include instrumentation and telecommunication circuits, signal-processing facilities, data acquisition and control circuits, medical and scientific applications, commercial and residential electronics, and aerospace or automotive applications. Additionally, it can be used as protective devices for current and voltage control, insulation, and grounding.

Specifications

The HHV1WSJT-73-22M has an operating temperature range of -55°C to +125°C. It has an operating resistance range of 0.1 Ohms to 400K Ohms and power dissipation range of 0.2W to 5W. Since it is hermetically sealed, it can be used in both indoor and outdoor operating conditions.

Working Principles

The HHV1WSJT-73-22M works using the same principles as other through-hole resistors. Generally, it works by limiting the amount of current passing through an electrical circuit. Voltage is supplied to one end of the resistor element, and the current is forced to travel through the resistive material, producing heat during the process. This heat is dissipated by excess current passing through the second terminal. By changing the resistance value, the amount of current allowed to pass through can be regulated.

Conclusion

The HHV1WSJT-73-22M is a through-hole resistor that is widely used in various industrial and commercial applications. Its ability to produce a precise resistance value makes it an ideal choice for a variety of uses ranging from telecommunications to instrumentation. It is hermetically sealed, making it suitable for indoor and outdoor applications. Its working principles are similar to other through-hole resistors, using resistance to limit the amount of current passing through the elements.
