Specialized Resistors
The ERA-S39J270V is an example of a specialized resistor. Its application field and working principle will be outlined in the following sections.
Application Field
The ERA-S39J270V is a high power, low ohmic surface mount resistor. It has an operating temperature up to +270°C in which it can operate. It is designed to be mounted on the side of the PCB instead of on the top, in a way that provides the lowest thermal resistance against the printed circuit board. This allows the resistor to handle higher power, while still keeping its temperature low. The ERA-S39J270V is suitable for applications such as power supplies, power converters, motor controls, engine controllers, automotive lighting, test systems, and other applications where high currents are required.
The ERA-S39J270V is also suitable for high power, low ohmic industrial grade resistor applications in LED lighting, power supplies, and other applications where high power and low temperature needs to be maintained. The ERA-S39J270V is also suitable for medical electronics applications, as it is UL1015 compliant and can withstand temperatures up to +270°C.
Working Principle
The ERA-S39J270V utilizes a unique technology which uses two independent resistors in series to protect from high power transient currents. The first resistor, a power resistor, has uniform resistance across all temperatures and is designed to interrupt excessive current. The second resistor, the current limit resistor, is designed to limit peak current and adjust resistance according to temperature. This combination of resistors works together to create a form of current limiting, which is ideal for applications where high currents must be sustained.
In addition, the ERA-S39J270V is designed with high thermal resistance, meaning that it is able to handle higher power dissipations without the temperature increasing a lot. This is due to its thick metal plate design, which effectively prevents the resistor from dissipating too much heat, keeping it cool and performing at optimal levels. The ERA-S39J270V is designed to handle multiple current levels, allowing the user to choose the best option for their application.
Overall, the ERA-S39J270V is a specialized resistor that offers high power, low Ohmic surface mount resistor capabilities in a wide range of applications. It is designed to be mounted on the side of the PCB and provides high thermal resistance, which allows it to handle higher power dissipations without risking damage or performance issues. It is also equipped with two independent resistors in series, allowing for current limiting and other protection measures. The ERA-S39J270V is suitable for use in automotive, industrial, test systems, medical, and LED lighting applications.
