Through Hole Resistors are among the most widely used components in electrical engineering. The SQMR72K0J is a type of through hole resistor that has a variety of applications and a simple working principle.

The SQMR72K0J is a 12W-rated, high-voltage, high-energy ceramic resistors. It is comprised of three main components: a high-pressure sintered block, a heat transfer film which covers the block, and an external protective shell. These resistors are used to protect circuits from transient overcurrents, as well as to consolidate multiple resistors in power applications. They are also used in waveform shaping and in noise-filtering applications.

The working principle of the SQMR72K0J follows the traditional resistors’ characteristics. By increasing or decreasing the voltage applied to the resistor, the current through it will increase and decrease, respectively. This change is relative to the amount of resistance the component applies to the circuit. If the voltage applied is low, the resistor will not exceed its rated wattage and consequently, its internal temperature will be controlled safely. The temperature control is made possible through the high-pressure sintered block, which improves the thermal conductivity, and the heat transfer film, which helps to dissipate the heat.

At the same time, the protective shell plays a key role in protecting the components from any external environmental effects, such as dust and moisture. The SQMR72K0J is also relatively low cost and its size makes it suitable for both through hole and surface mount applications.

Aside from providing overload protection, the SQMR72K0J is also capable of generating power, thanks to its large energy storage capacity. This power can be used to provide current or voltage in order to supply low power signals during peak intervals. It can also be used in power supply applications or to buffer peak currents. The SQMR72K0J can also be used to modulate tones for audio filtering applications.

Overall, the SQMR72K0J is a 12W-rated, high-voltage, high-energy ceramic resistor and it has been designed to provide protection from transient overcurrents, as well as to help create clean noise-filtered signals. It can also be used to generate power, or as a power supply during peak intervals. Since it is a through hole resistor, it is suitable for both through hole and surface mount applications.
