Through Hole Resistors play an important role in many electronic and electro-mechanical devices, particularly in high-frequency applications where the physical size constraints imposed by other resistor types limit their usefulness. The SQP700JB-110R is a general purpose, through-hole resistor used for both signal and power applications. This resistor is rated for power dissipation of up to 5 watts, which makes it suitable for a wide variety of applications.

The SQP700JB-110R is an axial-leaded resistor consisting of an insulated body and two terminated leads. The body contains an insulating substrate and a resistive component, which is constructed from a ceramic dielectric material with a homogeneous mix of metal oxide particles. The metal oxide mix is formulated to achieve a desired resistance value, and is applied to the substrate in the form of a screen-printed film. The film is then heated to further lock in the resistance value and improve temperature stability. The resistive component is then sandwiched between two layers of the dielectric, providing an environmental barrier and additional insulation from the leads.

The leads of the SQP700JB-110R are made of either copper or brass, depending on the current usage application of the resistor. Copper is used in low-current applications, as it offers better thermal conductivity and can dissipate heat more efficiently than brass. This helps to keep the resistor’s temperature within acceptable limits. Brass is used in higher-current applications, as it offers better electrical conductivity than copper and can carry higher currents. The leads are plated with tin to serve as a corrosion protection as well as a soldering aid.

The working principle of the SQP700JB-110R is simple. The electrical current passes through the resistor, generating a voltage drop across the resistor. This voltage drop is proportional to the resistance value and the current passing through the resistor. The voltage drop results in a loss of electrical energy, which is dissipated as heat. By varying the resistance value, the amount of voltage drop can be controlled.

The SQP700JB-110R can be used in a variety of applications, including current-limiting circuits, surge protection, voltage regulation, static voltage bias, radio frequency attenuation, and current sensing. It is particularly well suited for use in audio circuits, as its low resistance values and wide operating temperature range make it an ideal choice for low-noise, high-voltage applications. The SQP700JB-110R is also suitable for use in any environment that requires low-noise, reliable operation.

In sum, the SQP700JB-110R is a general purpose, axial-leaded resistor suitable for both signal and power applications. It offers excellent temperature stability and wide resistance value range, making it an ideal choice for many electronic and electro-mechanical applications. Its simple working principle allows for precise and repeatable control of voltage drop, making it ideal for applications such as current-limiting circuits, surge protection, and voltage regulation.
