Fixed Inductors are devices that store and transport electrical energy using a coil of wire. The ER1840-107JR is a popular fixed inductor with a wide range of applications and a simple yet effective working principle.
ER1840-107JR Applications
The ER1840-107JR is a popular fixed inductor, mainly used in switching regulator circuits, LED driver circuits, power supplies and other power management circuits. It is most commonly used to filter noise from the voltage supply and keep it stable over a wide temperature range. It is also used in passing high frequency noise and reducing its high frequency ripples. The ER1840-107JR has a high sensitivity level and can be used in digital circuits ranging from 4V to 20V. It is also designed for a low temperature coefficient and can be used in power management circuits operating up to 125°C. This allows for a reliable and stable operation even when the ambient temperature is high. The ER1840-107JR is built to last and is suitable for harsh environmental conditions. It is designed for an operating temperature range of -55°C to 125°C, which makes it suitable for industrial applications and military projects. It can also withstand vibration and shock, making it reliable in tough conditions.ER1840-107JR Working Principle
The working principle of the ER1840-107JR is based on the principle of electromagnetic induction. It works by storing electrical energy within the inductor’s core, which induces a magnetic field around it. When a current passes through the winding, it generates an electromagnetic field, which then interacts with the magnetic field of the inductor’s core. This produces a counter EMF (Electromotive Force) that opposes the flow of current, causing it to slow down. The amount of counter EMF generated depends on the inductance of the inductor, which is determined by the type of core material and size of the winding. The ER1840-107JR employs a multi-layer winding that is designed to reduce winding noise and improve its performance. The winding is wound on a toroidal core that is made of an amorphous based alloy. This type of core has a high saturation point and is very stable compared to other types of cores, allowing it to handle high current and maintain its inductance over a wide temperature range.Conclusion
The ER1840-107JR is a popular fixed inductor with a wide range of applications and a simple yet effective working principle. It is suitable for digital circuits ranging from 4V to 20V and can handle high current in tough environmental conditions. It is designed to reduce winding noise and can maintain its inductance over a wide temperature range. It is reliable and can withstand vibration and shock, making it suitable for industrial applications and military projects.The specific data is subject to PDF, and the above content is for reference
