Through Hole Resistors

Through hole resistors are widely used in a variety of fields such as industrial, medical, automotive, consumer and so on. In these applications, through hole resistors are used to reduce the power consumption in components, limit the current in circuits, and prevent electrical interference by attenuating the signals. One of the most commonly used through hole resistors is the SQM500JB-43R.

SQM500JB-43R Application Field

The SQM500JB-43R is a through hole resistor that is designed for applications where the power dissipation is greater than 500mW. Common applications include medical devices, automotive electronics, power supplies, and other ruggedized applications. The SQM500JB-43R is also widely used in the semiconductor industry as well as other industrial arenas where large amounts of power are required.

SQM500JB-43R Working Principle

The SQM500JB-43R uses a resistance element that is based on oxide-metal technology. The resistance element is a four-element structure. The first three elements are composed of a thin-film resistor, a layer of mu-metal, and a layer of low-temperature co-fired ceramics (LTCC). This structure creates a two-point contact which provides a high input current and low power dissipation. The fourth element is a layer of form factor-specific mechanical spring. This adds a fourth contact point which provides additional strength to the resistor and allows for a wide range of applications. To ensure the stability of the resistor, the SQM500JB-43R uses a patented process of laser-welding the contact points. This technique ensures that the contact points are firmly held in place and gives the resistor a break-before-make characteristic which protects against accidental connection problems. The SQM500JB-43R also has a low temperature coefficient, which ensures that the resistor remains stable over a wide range of temperatures. The resistor also features a self-suppression technology which helps to reduce the power dissipation and prevent over voltage.

Conclusion

Through hole resistors are an important part of many types of electronic devices and systems. The SQM500JB-43R is a popular through hole resistor that can be used in a variety of applications where high power dissipation is required. This resistor is designed to provide a reliable and stable performance while offering a wide range of features that ensure its stability and protection against connection problems.
