ER1840-135JP Fixed Inductor

The ER1840-135JP fixed inductor is an electrical component designed to maintain a specific electrical current or inductance. It is part of the Board Level Components used in the field of electronics and is broadly classified as Fixed Inductors. This inductor consists of a coil of insulated wire which is wound around a core material such as iron, ferrite or ceramic. The core forms a closed loop of magnetic flux around the inductor, efficiently developing the inductance needed for the application.

Features & Benefits

The ER1840-135JP Fixed Inductor is designed to provide long term reliability and has several features that make it attractive to a wide range of applications. These features include a low DCR current rating, high current saturation, low core loss, high frequency capability, high self-resonance, high thermal stability, and a high working temperature range. These features make the ER1840-135JP versatile and attractive for use in high power applications such as uninterruptible power supplies, solar energy systems, and computer power supplies.

Application Fields

The ER1840-135JP Fixed Inductor is ideally suited for use in a variety of application fields. It has superior current saturation and high frequency capabilities, making it suitable for use in high power applications. It can be used as an output coil for continuously regulated power supplies, making it especially desirable for use in DC-DC converters, DC-AC inverters, DC-DC switching regulators, and AC motor drives.

This inductor is also suitable for use in switched mode power supplies, high-speed synthesizers, low voltage regulators, and audio amplifiers. It is well suited for use in temperature and humidity sensing circuits, as well as in thermal protection controls. Its high self-resonance and low core loss make it especially useful in automotive and consumer electronics where space is at a premium.

Working Principle

The ER1840-135JP Fixed Inductor operates on the principle of magnetic induction. When an electrical current passes through the windings of the inductor, an electromagnetic field is created which opposes the change of current. By effectively controlling the amount of resistance that the inductor creates, the impedance of the DC current can be changed.

This inductor also contains a core material which helps to further increase the resistance of the inductor. As the magnetic field created by the inductor is increased or decreased, the inductance also shifts accordingly. As the inductance increases, it works to limit the amount of current allowed to pass through the inductor. As the current is restricted, the voltage is also limited, which provides the necessary stability for DC-DC converters and other power control systems.

Conclusion

The ER1840-135JP Fixed Inductor is an efficient electrical component that is well suited for a variety of application fields. Its features and working principle make it ideal for use in uninterruptible power supplies, solar energy systems, computer power supplies, switched mode power supplies, low voltage regulators, and audio amplifiers. Its high magnetic saturation and low core loss make it an excellent choice for automotive and consumer electronics systems. Its high working temperature range and high thermal stability ensure that the ER1840-135JP can perform dependably even under the most severe operating conditions.
