Introduction to Through Hole Resistors

Through hole resistors are a type of electrical component used to regulate electric current in a circuit. They are commonly used in electronics and electrical devices as they are relatively inexpensive and easy to install. Through hole resistors have two pins that are inserted into holes in a circuit board, allowing them to act as resistance points in the circuit, limiting the amount of current that passes through.

RWR78S3R74FRB12 Application Field and Working Principle

The RWR78S3R74FRB12 is a type of through hole resistor specifically designed for use in high voltage applications. Its two pins are securely mounted into the circuit board, allowing for secure and reliable connection. Its resistance value, given in Ohms, is related to the voltage applied to it. The current will be proportional to the applied voltage, with the resistance limiting the current.

The RWR78S3R74FRB12 is designed to work in circuits with high voltages up to 861V. This is a relatively high voltage rating for a through hole resistor, allowing the resistor to handle higher current loads without burning out. Its robust construction allows it to accurately regulate current in harsh environments, such as in high temperature circuits which are common in automotive applications.

The RWR78S3R74FRB12 is also designed to dissipate heat quickly, allowing it to regulate current accurately even in circuits with high currents. It utilizes a high quality internal construction that allows the resistor to quickly dissipate heat away from the resistor body, preventing it from becoming damaged due to overheating. This ensures that the resistor works at its maximum efficiency and does not become damaged due to excessive heat.

The RWR78S3R74FRB12 has a low tolerance rate, meaning that it is very accurate at regulating current in a circuit. It is designed to accurately adjust the current in the circuit, allowing the voltage to remain consistent and stable. This makes it ideal for use in applications where accurate current regulation is required, such as in automotive and medical applications.
