Through Hole Resistors, such as the SQM200JB-10K, play a major role in various electrical circuits. Through hole components are known for their high reliability, good self-healing and extremely low failure rate. The SQM200JB-10K resistor is specifically designed to maintain a desired resistive value and assist in the preventive measure against electrical damage. By understanding the application fields and working principle of the SQM200JB-10K resistor, its optimal usage can be ensured.

Application Fields

The SQM200JB-10K is a SMD resistor with a 200 kΩ resistance and a working voltage of up to 10 kV. Due to its dissipation capability and voltage rating, the SQM200JB-10K is an excellent choice for use in high-voltage, industrial-grade circuits. These circuits can include motor control, switching systems, circuit breakers, motor drives, and many other electrical operations that involve high voltages.

When using the SQM200JB-10K resistor, it\'s important to keep in mind other factors such as the temperature coefficient of resistance, temperature range and impedance value. If the power dissipation is too high, or the temperature range goes too high, then the device may not operate correctly. It\'s also important to note that the SQM200JB-10K resistors are non-linear, so that the resistance will not remain constant as the temperature of the medium changes.

Working Principle

The working principle of the SQM200JB-10K resistor is based on the ability to resist the flow of electric current. This is achieved by using a metal or ceramic material, or an insulating material which has a specific resistance to electrical current. The SQM200JB-10K is filled with a special type of ceramic material that has excellent temperature coefficient of resistance (TCR).

When a voltage is applied to the SQM200JB-10K resistor, the material inside the resistor starts to heat up. This causes the TCR of the material to increase, resulting in a higher resistance of the resistor. The increase in resistance is the main working principle of the SQM200JB-10K resistor.

The SQM200JB-10K is capable of operating in extreme temperatures and is designed to have a long life expectancy. The resistor is also designed to have a low stray capacitance, which helps to reduce the effects of EMI (electromagnetic interference). The SQM200JB-10K can also be used in larger capacitive loads, as the resistance will be evenly distributed across the load.

In conclusion, the SQM200JB-10K resistor is an ideal choice for high-voltage and industrial-grade circuits. Its high reliability, self-healing properties, and low failure rate make it a very reliable and safe component to use in these applications. By understanding its application fields and working principle, engineers can be sure that they are optimizing the use of this device.
