1812R-274J Description

Short technical summary and product information.

The 1812R-274J is a fixed inductor manufactured by API Delevan Inc. It features an inductance of 270µH with a tolerance of ±5%. The component is rated for a maximum current of 129mA and has a maximum DC resistance of 12 Ohms. It exhibits a typical Q factor of 40 at 790kHz and a typical self-resonant frequency of 4MHz. The inductor uses an unshielded ferrite core construction.

 

This inductor is designed for surface mount assembly and is housed in a 1812 (4532 Metric) package with dimensions of 4.50mm length, 3.20mm width, and 3.40mm height. It operates over a temperature range of -55°C to 125°C, making it suitable for a wide variety of environments.

 

Typical applications include filtering, energy storage, and impedance matching in electronic circuits. The unshielded design and ferrite core provide stable inductance over frequency and temperature.
