Fixed inductors are typically composed of an inductor core, a wire coil and a fixed case or housing. The ER1025-42JR is a corresponding fixed-inductor type. It is an axial and radial-leaded product, providing a low resistance DC power output with a high power-to-volume ratio, achieving high efficiency and low EM radiation. It has a broad range of free-air temperature range from -40 to +125°C. It is designed to meet the demands and requirements of a range of applications, such as computers, medical electronics, communications and motor drives.

The ER1025-42JR fixed inductor works on the principle of Faraday’s law of electromagnetic induction. Faraday’s law states that a changing magnetic flux produces an electromotive force (EMF) in a circuit. The EMF is equal to the negative of the rate of change of the magnetic flux in the circuit. The ER1025-42JR fixed inductor has a pair of wire coils, which serve as the primary and secondary coils. Current flowing through the primary coil induces a magnetic field that links the secondary coil. This induced magnetic flux is then converted into a voltage, creating the EMF.

The ER1025-42JR fixed inductor is widely used in all kinds of electronic circuits, especially in the power supply and control circuit. Its applications range from converting energy from one form to another, such as furnaces, inverters, contactless switches, audio amplifiers, etc. in industrial settings to charging devices such as cell phones in consumer electronics.

The ER1025-42JR fixed inductor is ideal for low voltage and high current operation. It offers excellent performance in terms of output voltage and current, with low noise and high durability. Its high power-to-volume ratio provides an efficient and reliable power source for a range of electronic products, meaning that smaller and lighter electrical systems can be designed.

The ER1025-42JR fixed inductor is also characterized by its very low on-resistance, which helps reduce energy loss, thereby increasing the efficiency of the device. The low on-resistance also means less heat is generated, allowing the device to operate at a much lower temperature.

Finally, the ER1025-42JR fixed inductor is a reliable and cost-effective component, suitable for a range of applications. Its low EM radiation allows it to be used in a variety of locations, including in medical or military applications that demand strict electromagnetic compatibility (EMC) requirements. As a conclusion, the ER1025-42JR fixed inductor offers many advantages and is the perfect choice for a variety of electronic applications.
