Through Hole Resistors, such as the H8120RFCA, are specialized resistors that are designed to provide reliable electrical isolation and resistance in electrical circuits. The H8120RFCA is a compact, hermetically encapsulated unit that features an embedded resistor element and non-polarized, fast-acting trimming terminals.

The H8120RFCA is a high-precision, multi-turn, full-range, through-hole resistor. It is constructed with a center axial terminal for trimming, eliminating the need for a separate ohmic resistor. It is constructed using a robust ceramic substrate, with a layered construction that includes a low-resistance silver-plated resistive element, along with two capacitors to reduce noise. It is designed with a total lead area of approximately 380 mm2, allowing it to be used in a variety of applications for audio, video, and digital circuits.

The H8120RFCA is designed to operate in environments where thermal or mechanical shock, vibration, or up to 10 cycles of high-temperature soldering is encountered. It features an excellent thermal shock resistance, and is rated for temperatures up to 400°C (752°F).

The working principle of the H8120RFCA is based on the principle of resistive current flow. As electrical current flows through the resistor element, its resistance value changes. This change is proportional to the voltage applied to the resistor element, causing a corresponding change in the voltage drop across the resistor. This change in voltage is what allows the H8120RFCA to regulate the electrical current flowing through it.

In addition to providing reliable electrical isolation and resistance, the H8120RFCA also has a number of other important advantages. These include a high-precision multi-turn full-range adjustable resistance, fast-acting trimming terminals, and a low-resistance silver-plated resistive element that is resistant to corrosion, vibration, and thermal shock. All of these features make the H8120RFCA an ideal choice for both commercial and industrial applications in a variety of industries.

The H8120RFCA is especially well-suited for applications in automotive, defense, and aerospace industries, as well as consumer electronics. It can be used in applications requiring reliable electrical isolation and resistance from acoustic noise, radio frequency interference, and high-frequency interference. It can also be used in applications requiring fast-acting trimming of resistance values, such as frequency synthesizers, antenna amplifiers, and switching converters.

The H8120RFCA is a reliable, compact, and versatile through-hole resistor that is designed to provide reliable electrical isolation and resistance in a variety of applications. Its robust design makes it an ideal choice for applications in a variety of industries, from automotive and defense to consumer electronics. It features low-resistance silver-plated resistive elements, fast-acting trimming terminals, and an embedded resistor element that allows it to regulate current flow, providing reliable electrical isolation and resistance.
