Through Hole Resistors are one of the most common types of resistors used in the electronics industry. The SQZ700JB-120K is a particular type of through hole resistor. Its application field, working principle, and other aspects are worth discussing in greater detail.

Application Field

The SQZ700JB-120K is a through hole resistor that is commonly used in industrial automation systems, automobiles, and consumer electronics. This type of resistor owes its popularity to its small size and extremely strong resistance, which can withstand temperatures ranging from -55°C to +155°C. Because of its low resistance and excellent thermal endurance, it is often used in projects that require components to perform in a reliable manner in high-temperature environments. Additionally, its long-term stability makes it a great choice for projects that require a consistent electrical resistance.

Operating Principle

The basic operating principle of a SQZ700JB-120K is simple. It is essentially a two-terminal device that creates a designated electrical resistance when connected to a power source. The resistance created is determined by the size and material of the resistor. In this case, the resistor has a size of 0805 inch and its material is metal film qualified according to BS EN 60068-2-20. This new technical material provides high stability while consuming a small amount of power.

The operating principle is augmented by the use of insulation to prevent electrical shorts. The material used for the insulation can be polyester or other qualified materials. The insulation carries a temperature rating that enables the component to operate at high temperatures. For instance, the insulation is capable of withstanding temperatures as high as 155°C. This ensures a safe and reliable operation when the resistor is used in high-temperature environments.

Other Considerations

In addition to its application field and operating principle, there are a few other important aspects to consider. The device is rated for a maximum power of 120K and a rated voltage of 400V. This makes it suitable for use with various applications, such as power supplies, motor controls, transformers, and so on. Additionally, the resistor is flame-resistant and self-extinguishing. This helps to ensure that it is able to perform reliably in the presence of an open fire.

The SQZ700JB-120K is an indispensable component in the electronics industry. Its application field, working principle, and other considerations make it a popular choice for industrial automation systems, automobiles, and consumer electronics. Being qualified according to BS EN 60068-2-20, it is a device that offers excellent performance and reliable operation in both high- and low-temperature environments.
