Through hole resistors offer reliable, stable operation and are most commonly used for applications like power distribution, electrical isolation, signal conditioning, and protection. They are used in a variety of applications, including audio, automotive, military, and even medical equipment. The SQM700JB-1K is one such resistor that is often used in these applications, and understanding its capabilities, application field, and working principle will be useful for choosing the right resistor for your project.

Application Field

The SQM700JB-1K is a through hole resistor with a very high resistance, 0.71k ohm. This resistor is best used for high-impedance applications where high-valued resistance is required, such as a voltage divider or filtering. Its high resistance makes it ideal for applications that require a large signal change with minimal current. High resistance is also beneficial for preventing spurious signals from interfering with the operation of other circuitry.

This resistor is also great for applications with a need for high accuracy and low temperature coefficient. This makes the SQM700JB-1K an ideal component for precision applications, such as in medical equipment where highly precise electrical characteristics are required to ensure accurate diagnostics. Additionally, because of its high resistance, the SQM700JB-1K can be used as a simple current limiter.

Working Principle

The SQM700JB-1K is an ohmic resistor, meaning that it operates on the principle of creating a voltage drop across the resistor as a result of current that passes through it. The voltage drop is proportional to the current and can be calculated using Ohm’s Law. This resistor is made up of two components: the conventional wire-wound coil element, and a metal oxide film construction.

It has a high power rating, allowing it to dissipate a great amount of power without suffering from excessive heat or failure. The resistance value of the SQM700JB-1K does not change with temperature variations, making it highly stable and reliable even in the most demanding environments. Its high reliability makes it suitable for use in applications where high voltage and current are expected.

The SQM700JB-1K also features high frequency characteristics. This is important for applications where high frequencies need to be filtered, such as in audio amplifiers and other circuits where precise signal conditioning is required.

Conclusion

In conclusion, the SQM700JB-1K through hole resistor is an ideal choice for applications that require high-valued resistance, superb accuracy, excellent high frequency characteristics, and low temperature coefficient. The high power rating of this resistor also makes it suitable for use in applications where large amounts of power are necessary. Understanding the capabilities, application field, and working principle of the SQM700JB-1K is essential for proper design and type selection.
