Working Principle

The working principle of the resistor is simple. When a voltage is applied to the resistor, the current flows through it, and depending on the design, some of the energy is dissipated in the form of heat, or on-resistor voltage drop. This process is known as Ohm\'s law, which states that the current is equal to the voltage divided by the resistance. The resistance is usually specified in ohms (Ω) or kilo ohms (kΩ).

The SQZ500JB-4K7 is a 4.7 Kohm (kΩ) resistor, meaning that the current is equal to the voltage divided by 4.7 KΩ. The voltage applied to the resistor also determines the amount of power dissipated and thus affects the temperature of the resistor. Therefore, it is important to choose the correct resistor value for the application, in order to prevent excessive power dissipation and overheating.

To allow for temperature compensation and stability, this type of resistor is typically made with a temperature-stable film such as Nitinol or NTC. This helps to minimize the impact of temperature on the performance of the resistor.

In summary, the SQZ500JB-4K7 is a through-hole resistor that is designed for applications that require high accuracy and stability. It is widely used in automotive electronics, industrial control, instrumentation, and medical applications.
