Through Hole Resistors (THR) are electrical components designed for the purpose of electrically isolating two circuits together. These components can be used for countless applications ranging from high voltage protection to limiting the current in a circuit. The most common types of THR are carbon-based, metal-oxide, and wire wound. With each of these type offering various levels of resistance, it is important to select the THR for the specific application.

The SQP30AJB-56K through hole resistor is a ceramic over aluminum-based devicethat is designed for high frequency and high power applications. The SQU30AJB-56K has a rated power of 30 watts and a rated voltage of 56kV. The maximum operating temperature of is 97ºC and maximum operating altitude is 0.3 km. This THR also has a high-frequency operating range of 20 kHz to 30 GHz.

The construction of the SQP30AJB-56K THR is a combination of a copper rod terminal and a ceramic body, the ceramic over aluminum is a type of non-resistor screening material. This unique combination of material creates a high-frequency, low-loss, low-noise resistor. With this design, the SQU30AJB-56K is well suited for the high-frequency applications and can be used in a wide variety of circuit types used in the communications industry such as base station, fixed wireless access, cell phone, and satellite radio.

The working principle of the SQP30AJB-56K THR is that of a three-leaded, three-winding, ceramic-over-aluminum type resistance device. The ceramic body serves as the “barrier” between the copper terminals and the aluminum contacts in order to reduce the amount of energy transferred between the two components. This allows the resistance device to act as an insulator between the two circuits. By placing the resistance device in a circuit, it will reduce the amount of energy flow or current between the two circuits. This is accomplished by the resistor draining off the noise or interference that is present in the circuit.

The most common uses of the SQP30AJB-56K THR include its use in high frequency communication systems, such as satellite or base station systems. The SQP30AJB-56K THR is also used in high-power systems that require high frequency protection, such as electric power grids and surge protection systems. This THR is also used as part of power converter modules for electronic motor drives, power modules, and power regulators.

In conclusion, the SQP30AJB-56K through hole resistor is a highly specialized component with a number of uses due to its combination of ceramic over aluminum construction and its ability to provide a high-frequency, low-loss, low-noise resistance device. Its applications include high frequency communications, high-power protection systems, and as part of electronic motor drives and power modules. The working principle for this THR is that of a three-leaded, three-winding, ceramic-over-aluminum type resistance device. This THR is well designed for its intended use and can provide a reliable and effective performance in high frequency applications.
