Through Hole Resistors

Introduction to Through Hole Resistors
Through hole resistors are components used in electronic designs to restrict current flow in order to regulate voltage levels or provide feedback to a circuit. A resistor is essentially a passive electrical component that is made up of a thin metal film or wire wound around a cylinder or similar shaped structure. The material of the resistor, along with its physical characteristics like the number of turns, determine its resistance. Resistors are connected between two terminals and act as a load, dissipating energy in the form of heat. The resistance of the resistor is rated in Ohms (Ω).

SQZ700JB-160R Application Field and Working Principle
The SQZ700JB-160R is a through hole resistor designed to provide reliable power control in a wide range of electronic equipment. It is a single turn, cylindrical shaped resistor with a maximum power rating of 100 watts. The resistor is made of a cobalt alloy film with a resistance range of 160 Ohm. The SQZ700JB-160R is designed for maximum safety and reliability, with a ceramic insulation layer providing additional protection from heat, moisture and dust. The resistor is qualified to UL94-V0, making it ideal for applications where high reliability and voltage protection are required.

The SQZ700JB-160R works on the principle of Ohm’s Law. When a current is applied to the resistor, an electrical potential difference is produced across its terminals. This resistance-dependent potential difference allows the resistor to regulate current flow, thus limiting the voltage in the circuit. The current is restricted based on the resistance value of the resistor and the total current flowing through the circuit.

Most popular types of through hole resistors include metal film, wire wound, and carbon composition. Metal film resistors are made of a thin metal film deposited on a ceramics substrate, providing a highly repeatable and reliable resistance value. They are the most commonly used type of resistor and are ideal for applications requiring high precision and low noise. Wire wound resistors are typically used in high power applications as they have low levels of contact resistance, high stability, and low heat dissipation. Carbon composition resistors are formed by mixing carbon and filler material such as alumina or glass, providing a relatively low cost yet very reliable alternative.
