Through hole resistors have become an integral part of electronics engineering. The SQM 700JB-12K is a type of through hole resistor that are becoming increasingly popular in electronic applications. This article will discuss the application field and working principle of the SQM 700JB-12K resistor.

The SQM 700JB-12K through hole resistor uses carbon film as the main resistive material and is primarily used for applications requiring a high resistance value, such as high current applications. It has an operating temperature range of –65 to +150°C, with a maximum voltage rating of 800V. The resistance value range is from 100K ohm to 1M ohm and its tolerance is +/-5%. It is also notable for its low distortion time, making it suitable for audio applications.

In operation, the SQM 700JB-12K uses carbon film deposited in the form of a conductive path on an insulating substrate. The resistor acts as a conductor when a current passes through it. The film acts as a resistor that reduces the flow of electrons. This helps in limiting the amount of current flowing through the electrical path. The resistance value of the carbon film is determined by its coating thickness, distance between the conductive paths, and the diameter of the substrate.

The SQM 700JB-12K through hole resistor is most commonly used in audio amplifier circuits. Its high resistance value prevents oscillations from occurring in the signal path. It can also be used in TV circuit applications, where it is used to limit the current flow in a given circuit. This helps to protect the components from arc discharge, which may occur due to an excessive current in the circuit. It can also be used in automotive systems to adjust the charging current of a battery or to limit the power output of a device.

The SQM 700JB-12K through hole resistor is an ideal choice for many through hole electronic applications. Its high resistance value and low distortion time make it suitable for audio applications, and its operating temperature range makes it suitable for a wide range of applications. The resistance value is determined by adjusting the coating thickness, distance between the conductive paths, and the diameter of the substrate, which makes it very versatile. The long life and high reliability make it a cost effective component for any application.
