Fixed inductors are one of the most popular passive electronic components, and are widely used as inductors in power circuits to provide beat suppression, filters, impedance matching or noise reduction. IHSM3825ER100L is a series of fixed inductors produced by Murata, which is often used in various electronic devices. This paper will introduce the application field and working principle of these inductors.

IHSM3825ER100L is suitable for use in applications such as current-mode DC-DC converter, step-up converter, automotive electronics, power management, power supply, precise control circuit and telephone line cord. Because these applications often require relatively high power, the IHSM3825ER100L can operate reliably and stably at a temperature of up to 150 degrees Celsius while dissipating up to 4.2W of power. In addition, the series has a wide operating temperature range (-55~150℃) and a wide inductance range (10uH to 10000uH). The filtering performance is also remarkable, which makes it indispensable for sensitive circuits such as power supply and switching power supply. Moreover, Murata manufactures these inductors with SMT (surface mount devices) technology, enabling quick and practical assembly and high efficiency in mass production.

In addition to its excellent performance, the application of IHSM3825ER100L is based on its working principle. In a fixed inductor, the inductance is mainly determined by the inductor\'s magnetic circuit structure and core material. Therefore, the IHSM3825ER100L applies nanocrystalline power cores to increase the inductance and strength. When a current passes through the inductor, the magnetic circuit formed by the current-carrying wire and the core generates a magnetic field which wraps around the wire and changes linearly with the change in the current value. When the current in the induction wire changes, the magnetic field around it will produce an induced electromotive force, that is, energy is stored in the form of electromagnetic induction. This energy will try to prevent the changes in the current, which is known as inductance, also known as self-inductance.

In conclusion, IHSM3825ER100L is a series of fixed inductors produced by Murata, and is widely used in various electronic devices. Its wide range of operating temperatures and wide range of inductances make it ideal for high-power environments. In addition, its working principle is based on self-inductance, and its ability to store current makes it suitable for use in controlling operating current and protecting sensitive components in related electronic products.
