Through hole resistors have been ubiquitous in designing power supplies and filters since the introduction of the technology in the 1970s. The HHV-50FT-52-20M, in particular, is a versatile component that is used in many applications. This article will provide a basic overview of its application field and working principle.

Application Field

The HHV-50FT-52-20M is a through-hole resistor. It is typically used for current limiting and decoupling in power supply designs. It is also useful in filter designs as a low-profile replacement for leaded components, especially where space is a premium. Additionally, it finds application in audio circuits, including for impedance matching, and in linear power supplies as a boundary conditions for power factor correction.

Working Principle

The HHV-50FT-52-20M is a resistance element which includes a ceramic body, copper leads, and two resistive elements. The resistive elements are made up of a homogenous, electrically isolative, ceramic oxide material which is stable and reliable even in harsh environmental conditions. Current is conducted between the two resistive elements through the copper leads, and the resistance is determined by the ceramic oxide\'s resistance to the applied voltage. The resistor\'s maximum dissipation power is limited by the heat-dissipation ability of the ceramic body, which is specified in the resistor\'s datasheet.

When applying voltage or current to the HHV-50FT-52-20M, the resistive elements will dissipate power, producing heat which is transferred to the ceramic body and dissipated as heat radiation. This temperature increase is limited by the ceramic body, which must be designed and sized to ensure that the resistor does not overheat and cause damage.

In designing a power supply with the HHV-50FT-52-20M, the resistor\'s working principle as a resistive element must be kept in mind. It is important to monitor the dissipated power as well as the resistor\'s temperature, as excessive temperatures will cause damage and potentially reduce the component\'s life span. Additionally, the resistor\'s value must be considered when designing a power supply, as its dissipated power and temperature rise will depend on the wattage rating of the resistor.

Conclusion

The HHV-50FT-52-20M is a versatile component that is used in many applications. It is a through-hole resistor that is typically used for current limiting and decoupling in power supply designs, as well as for audio circuits and power factor correction. The resistor works as a resistive element, and its maximum dissipation power is limited by the heat dissipating ability of the ceramic body. When designing a power supply with the HHV-50FT-52-20M, the resistor\'s working principle as a resistive element must be kept in mind.
