1812R-123J Description

Short technical summary and product information.

The 1812R-123J is a fixed inductor manufactured by API Delevan Inc. It offers an inductance of 12 µH with a tolerance of ±5%. The component is rated for a maximum DC current of 317 mA and has a maximum DC resistance of 2 Ohm. The self-resonant frequency is 18 MHz, and the Q factor is 50 at 2.5 MHz.

 

The inductor features an unshielded ferrite core and is designed for surface mount assembly. It is housed in a 1812 (4532 Metric) package with dimensions of 4.50 mm length, 3.20 mm width, and 3.40 mm height. The operating temperature range spans from -55°C to 125°C, making it suitable for a wide variety of environments.

 

Typical applications include RF circuits, impedance matching, and general purpose filtering where a moderate inductance value and low DC resistance are required. The unshielded construction allows for higher Q but may require careful PCB layout to minimize coupling.
