1812-101K

The 1812-101K is a fixed inductor from API Delevan Inc., designed for surface-mount applications. It features an inductance of 100nH with a ±10% tolerance, and is rated for a continuous current of 818mA. The inductor has a maximum DC resistance of 300mOhm, ensuring efficient power handling in compact designs.

With a Q factor of 30 at 25MHz and a self-resonant frequency of 650MHz, this unshielded inductor is suitable for RF filtering, impedance matching, and general signal conditioning circuits. Its iron core material provides stable inductance over a wide temperature range of -55°C to 125°C.

The component is housed in a standard 1812 (4532 Metric) package with a height of 3.40mm, making it compatible with automated assembly processes. The surface-mount design allows for high-density PCB layouts, reducing board space and improving thermal performance.

For design engineers, the low DCR and high current rating make this inductor useful in power supply circuits, while the self-resonant frequency supports operation in high-frequency applications. The unshielded construction should be considered in layouts with nearby sensitive components.
