Introduction to Through Hole Resistors - ERD-S2TJ3R9V

Through hole resistors, also known as “through-hole” or “leaded” resistors, are resistors that are soldered into place onto the printed circuit board (PCB). The ERD-S2TJ3R9V is a through-hole resistor developed by the Japanese electronics company, Choshin. It has been designed and developed to meet the high quality standards set by the International Electrotechnical Commission (IEC).

Application Field and Working Principle

The ERD-S2TJ3R9V through-hole resistor is commonly used in a variety of industries, notably in electronics and automotive applications. It can be used as a voltage divider, current splitter, and as an automatic protection device. The ERD-S2TJ3R9V is constructed using a cylindrical carbon film resistor element. Its solderable terminations enable a secure soldering connection and its leaded construction allows it to be installed with a precision once the pin momentary contact has been established.The ERD-S2TJ3R9V´s temperature coefficient is relatively low (0.065%/°C). This combined with its leaded construction make it suitable for more demanding and high temperature applications since it is able to withstand temperatures up to 350° C.The ERD-S2TJ3R9V is a non-inductive low power resistance element and has a maximum rated resistance of 10K ohms. Additionally, it has a high stability in its electrical conditions; temperature affects on this resistor are minimal, providing consistent operation even in environments with wide temperature fluctuations.The ERD-S2TJ3R9V also provides a wide range of voltage and resistance values, with an operating range from 0.2V to 200V. This range enables the resistor to be used in many power supply circuits such as those found in televisions, computers, car audio systems, and other electrical appliances. Additionally, the ERD-S2TJ3R9V is able to meet many Environmental requirements like the requirements for RoHS, REACH, and Halogen Free. For instance, the resistor is able to withstand the effects of humidity, water, oil, and combustion from exhaust gases, making it a suitable choice for automotive applications.

Conclusion

The ERD-S2TJ3R9V through-hole resistor is an excellent choice when high-quality components are needed for through-hole application fields. Its high stability against temperature fluctuations, leaded construction, and non-inductive characteristics make it suitable for a wide variety of industrial applications. Additionally, its wide operating range and resistance values, combined with its RoHS, REACH, and Halogen-free certifications, make it a safe and trusted choice for engineers and designers.
