1812-684J Description

Short technical summary and product information.

The API Delevan 1812-684J is a fixed inductor designed for surface mount applications. It features an inductance of 680 µH with a tolerance of ±5%. The component is rated for a maximum DC current of 82 mA and has a DC resistance of 30 Ohm maximum. The inductor operates over a temperature range of -55°C to 125°C.

 

This unshielded ferrite core inductor exhibits a self-resonant frequency of 3 MHz and a Q factor of 30 at 790 kHz. These characteristics make it suitable for use in RF filtering, impedance matching, and DC-DC converter output filtering circuits where moderate inductance and low current handling are required.

 

The component is housed in an 1812 (4532 Metric) package with dimensions 4.50 mm length, 3.20 mm width, and 3.40 mm height. It is supplied in tape and reel packaging for automated assembly. The part is RoHS3 compliant and REACH unaffected, with MSL 1 unlimited rating.
