Through Hole Resistors

A through hole resistor, also known as a locking resistor, is a passive electronic component typically used in electrical engineering and electronics. It includes thick-film, mini-MELF (metal-electrode lead-free), and surface-mount, which are available in a variety of packages, sizes, and configurations. All of these types provide the same basic electrical functionality and are separated mainly by their size and shape. The most common type of through hole resistors are made of a ceramic material.

H4187RBCA Application Field and Working Principle

H4187RBCA is a unique type of through hole resistor currently offered by Bourns Electronic Solutions. It is a high-power, heavy-duty, 4-terminal resistor that is designed to reduce EMI interference on power supply wiring and other high-frequency sources. It is available in a variety of resistance values and current ratings, allowing it to be used in a wide array of applications. H4187RBCA is ideal for power supply and EMI filtering on motor drives, pumps, HVAC systems, audio-video systems, and other electronic systems that may be prone to RF interference.

The working principle of the H4187RBCA is quite simple. The resistor is placed between two conductors and acts as a small resistance between them to reduce the amount of voltage and current that passes through it. The device is essentially a resistance element, which consists of two separate resistors connected in series with a terminal connector. The advantage of this configuration is that it allows for a high power rating and current rating, meaning greater protection and more efficient EMI reducing capabilities.

The application field for H4187RBCA is broad. It can be used in automotive, aerospace, industrial, consumer, and commercial applications. In addition, it can be used in a wide range of high-frequency application, such as EMI/RFI filters and power supply wiring. Additionally, it is commonly used in DC to AC converters, solar power supplies, and other high- power applications to provide superior noise reduction capabilities.

Overall, the H4187RBCA is an ideal solution for a variety of applications, providing a high level of protection against EMI interference. Its high power rating and current rating make it an excellent choice for applications that require reliable EMI reduction and power supply wiring solutions.
