Through Hole Resistors have been used in the electronics industry since the early 1900s. They are relatively inexpensive and come in many shapes and sizes. Their primary use is to resist the flow of current in a circuit. In particular, the SQM200JB-51R is a through-hole resistor that is used in many different applications and has a working principle that is relatively simple.

The SQM200JB-51R is a through-hole resistor with an axial lead, meaning the lead goes through the center of the resistor, allowing it to be easily mounted to a circuit board. It has a resistance of 200 ohms and can withstand up to 5 watts of power. It has a working temperature range of -55C to +200C, and is rated for an operating temperature of 70C.

The SQM200JB-51R is most commonly used in high voltage power circuits. It can be used as a successful current limiter in circuits that exceed a certain voltage level, protecting components from being subjected to excessive voltage. The resistor also serves to reduce voltage and current surges, helping to maintain stability in the circuit.

The working principle of the SQM200JB-51R is actually quite simple. During operation, the resistor allows a certain amount of current to flow through it, dependent on the supply voltage. The SQM200JB-51R is designed to operate in a linear region for most applications. As the voltage across the resistor increases, so does the current. This current is then limited by the resistance value of the resistor, ensuring that the circuit does not exceed its current limit.

The SQM200JB-51R is a versatile and reliable resistor, and has a variety of applications. It can be used to limit current in high voltage circuits, as well as to reduce voltage and current surges. It is also a useful tool for prototyping projects and testing circuits. The resistor is relatively inexpensive, making it an attractive choice for many electronics applications.
