Fixed inductors play an important role in many electronic circuits. The ER1840-09KR is a type of fixed inductor that is suitable for a variety of electronic applications. In this article, we will discuss the application field and working principle of the ER1840-09KR.

Application Field

The ER1840-09KR is a surface mount fixed inductor. It has a maximum inductance of 470nH and a rated current of 0.9A. The inductor size is 18mm x 18mm and the height is 8mm. This inductor is suitable for a variety of applications, including DC/DC converters, power supplies, transistor switching circuits, tuned circuits, and amplifier circuits.

Working Principle

The working principle of the ER1840-09KR is based on the principles of electromagnetic induction. This type of inductor has two halves, the core and the winding. An alternating current is placed through the winding, which then interacts with the core to produce an electromagnetic field. This field induces a magnetic field in the core, which in turn causes a current to be created in the winding. This current is known as the induced current. The magnitude of the induced current depends on the inductance of the inductor and the frequency of the alternating current.

The ER1840-09KR is designed with an internal air-core structure. The air-core structure reduces the leakage impedance of the inductor, allowing for increased current handling capacity. This structure also limits the magnetic field and helps to reduce the risk of interference with other components in the circuit.

The ER1840-09KR has a minimum self-resonant frequency of 500MHz, making it suitable for use in high-speed circuits. This type of inductor is also suitable for use in circuits that require low power losses. The inductor has a maximum temperature rise of 10°C, making it safe to use in temperature-sensitive circuits.

The ER1840-09KR is designed with an RoHS-compliant, lead-free terminal. This allows for easy and reliable application in any circuit design. The terminal is also designed to be resistant to EMI and RFI interference.
