Fixed inductors are electrical components commonly found in electronic circuits, providing a stable inductance. They are often used in power supplies, audio amplifiers, and signal conditioning circuits due to their ability to suppress the passage of alternating currents while allowing the passage of direct currents. The ER1537-01KM is a fixed inductor designed for applications such as charge pumps, DC-to-DC power converters, RF applications, and switching power supplies.

The ER1537-01KM is a surface-mount fixed inductor measuring just 12.4mm in length and 9.7mm in width. It has an inductance of 1.8 mH and an operating temperature range of -40 to +105°C, making it suitable for use in a wide variety of industrial, consumer, and automotive applications. The inductor is made from a high-grade sputtering iron-powder core to ensure long-term stability and a low temperature coefficient. It also features a fully moulded structure, making it highly resistant to moisture, dirt, and dust.

The ER1537-01KM has an ESR (Equivalent Series Resistance) of 0.22 Ω and a rated current of 8.7A. This ensures high efficiency in power circuits, helping to reduce the amount of wasted energy. The inductor also has a high self-resonant frequency of 50MHz, allowing it to be used in a wide variety of high-frequency applications. The inductor is also rated with a dielectric strength of 800V, allowing it to be used in high-voltage circuits.

The ER1537-01KM is designed to work in a wide variety of applications, including switch-mode power supplies, DC-to-DC power converters, RF applications, and charge pumps. In switch-mode power supplies, the inductor works by storing energy by generating a magnetic field when current passes through it. This stored energy can then be used to power the load of the circuit. In DC-to-DC power converters, the inductor is used to provide isolation between the input and output circuits. This helps to reduce noise and interference caused by switching and helps to ensure that the DC output is of a usable voltage.

In RF applications, the inductor works to suppress signals over a specific frequency range. This helps to reduce interference and allows signals to be filtered more effectively. In charge pumps, the inductor acts as a bridge between two capacitors. This helps to provide a more stable current for the circuit, allowing it to operate more efficiently.

The ER1537-01KM fixed inductor is a reliable and versatile component that can be used in a wide variety of applications. Its high ESR and rated current ensure high efficiency, while its dielectric strength of 800V proves it to be a component suitable for high-voltage circuits. Its ability to work in RF applications and charge pumps make it an ideal choice for both industrial and consumer applications.
