Through Hole Resistors

Through-hole resistors are resistors, as the name suggests, which are designed to be mounted directly to the circuit board. They consist of a ceramic body, with a metal plate and a resistive element inside. The resistance value of a through-hole resistor can range from a few ohms to several megohms. Through-hole resistors are the most commonly used type of resistors in consumer products, due to their affordability, ease of assembly and ability to handle a wide range of electrical currents.

The SQM700JB-39K is a through-hole resistor specifically designed to control the amount of power flowing through a circuit. It is a metal oxide resistor designed for applications requiring high power ratings and low inductance. The SQM700JB-39K is designed to handle 150 watts of power with an operating temperature range of -55C to 250C. This type of resistor is primarily used in power routing and regulation applications.

The operating principle of the SQM700JB-39K is quite simple: it allows a specific amount of current to travel through the resistor, while preventing excess current from passing. The operating principle can be described as Ohm’s law (E=I x R), where E (Voltage) is equal to the current flowing through the resistor (I) multiplied by the resistance value of the resistor (R). The resistance value is determined by the material used to make the resistor and the physical size of the resistor.

In addition to Ohm’s law, the SQM700JB-39K is designed to adhere to a number of international safety standards, such as UL and IEC, as well as specific industry standards, such as the SMMA and SAE 800 specifications. These standards help ensure that the resistor meets certain safety and performance criteria so that it can be safely used in a variety of applications.

The SQM700JB-39K is a versatile through-hole resistor that can be used in a wide range of applications, such as motor control, lighting control, power circuits, circuit protection, power supply design, and many more. It is the perfect choice for applications where a resistor is required but a chip is not. The SQM700JB-39K is a reliable, cost-effective and energy-efficient solution for many power-control applications.
