Through Hole Resistors are one of the most widely used components in the electrical and electronics industry, and are found in nearly every device from industrial equipment to consumer electronic products. The SQMR520KJ is a popular through-hole resistor, so let\'s take a closer look at its application field and working principle.

The SQMR520KJ is a carbon-film resistor, meaning it is composed of a coil of resistive wire covered with insulation materials and sealed in an epoxy package. The resistance of the resistor can be adjusted by changing the size and number of coils used. The SQMR520KJ resistor has an insulated case and a leads of 5mm in length, making it an excellent choice for applications in which space is limited.

As for its application field, the SQMR520KJ resistor can be used for voltage stabilizing, current limiting, and signal regulating. It is particularly useful in power supplies and power regulators. For example, it can be used to adjust the current in a DC-to-DC converter. It can also be used in automotive electronics, HVAC systems, audio equipment, medical devices, and several other electronic products and applications.

The working principle of the SQMR520KJ takes advantage of the Ohm\'s law to produce a precise voltage drop across a resistance. When a voltage is passed through the resistor, a certain amount of current will flow through it according to Ohm\'s law. This current can then be used to regulate the output voltages of the circuit. For example, if a voltage is applied to the resistor, a certain amount of current will pass through the resistor, thus decreasing the output voltage of the circuit.

In addition, the SQMR520KJ can also be used to limit high current. When a current passes through the resistor, a certain amount of voltage is dropped across the resistor, thus limiting the current that can flow through the device. This makes it useful in applications where current must be limited, such as automotive electronics and audio equipment.

In conclusion, the SQMR520KJ is a popular through-hole resistor that is widely used in the electrical and electronics industry. Its wide application field and simple working principle make it an excellent choice for applications where space is limited, as well as applications where current must be limited.
