Fixed Inductors

The ER1641-183KP is a fixed inductor, which is designed for high stability and reliability operation. It is most commonly used in line transformer applications and other high-frequency applications which require low-loss inductance. This inductor features a ferrite core with a non-magnetic iron core for high performance and low self-capacitance. It has high insulation resistance and insulation volumetric efficiency, which makes it suitable for use in high voltage environments.

This inductor is a cost-effective solution for applications that demand precise inductance at high frequencies, such as decoupling of power supplies, EMI suppression filters, and noise suppression in digital circuits. It can also be used as an RF choke in high frequency applications such as power dividers and couplers, and in telecommunications applications.

The ER1641-183KP has a rated inductance of 18.3mH. Its DC resistance is 0.22ohms, and the SRF is typically 10MHz. The maximum operating temperature is +125℃ and the maximum ambient temperature is 80℃. The inductor has a low profile of 17mm with a height of 5mm and a diameter of 7mm, which makes it suitable for use in tight spaces. The rated current is 1.2A.

The ER1641-183KP is a surface mount device with lead-free solderable terminals. It can be quickly and easily installed using standard pick-and-place assembly techniques. The inductor is RoHS compliant and is available in Tape & Reel packaging or Bulk Box packaging.

Working Principle of ER1641-183KP

When current passes through the coil of an inductor, it induces a magnetic field around the coil. This magnetic field then generates a voltage across the coil\'s two terminals, which in turn produces an electrical current through the inductor. This current, known as the inductance, is proportional to the amount of current that flows through the inductor and is usually measured in Henries.

The ER1641-183KP is a fixed inductor, which means that it has a fixed inductance value that does not change significantly in response to changes in current. This makes it ideal for use in pulsed circuits, where the inductance needs to remain constant, or in applications where a specific inductance is desired. This also makes the ER1641-183KP a good choice for EMI suppression, as it can help reduce EMI emissions from the circuit.

In addition to its fixed inductance value, the ER1641-183KP also has a low profile and low self-capacitance, which makes it suitable for high-frequency applications. Its ferrite core construction helps reduce losses at high frequencies, making it an excellent choice for applications that require precise inductance values at high frequencies. Lastly, its lead-free solderable terminals enable fast and easy surface mount assembly.
