1812-273J Description

Short technical summary and product information.

The 1812-273J is a fixed inductor from API Delevan featuring 27µH inductance with ±5% tolerance. It uses an unshielded ferrite core and is rated for 236mA continuous current with a maximum DC resistance of 3.6 Ohms. The inductor offers a Q factor of 50 typical at 2.5MHz and a self-resonant frequency of 12MHz, making it suitable for RF and general purpose filtering applications.

 

This surface mount inductor operates over a temperature range of -55°C to 125°C, ensuring reliability in harsh environments. It is housed in a 1812 (4532 Metric) package with dimensions 4.50mm x 3.20mm x 3.40mm, compatible with standard SMD assembly processes. The packaging is Tape & Reel (TR) for automated pick-and-place.

 

The component is designed for use in DC-DC converters, signal filtering, and impedance matching circuits where moderate current and high inductance stability are required.
