1641-122K Description

Short technical summary and product information.

The 1641-122K is a fixed inductor manufactured by API Delevan Inc. It features a nominal inductance of 1.2 µH with a tolerance of ±10%. The component is rated for a continuous current of 900 mA and has a maximum DC resistance of 100 mOhm. The inductor is shielded and constructed with an iron core in a molded design, providing stable performance in various applications.

 

Electrical characteristics include a Q factor of 44 at 7.9 MHz and a self-resonant frequency of 130 MHz. The operating temperature range spans from -55°C to 105°C, making it suitable for environments with wide temperature variations.

 

The inductor is packaged in an axial through-hole configuration, with dimensions of 0.162" diameter by 0.410" length (4.11 mm x 10.41 mm). This package style allows for easy insertion into printed circuit boards and is commonly used in power supply filtering, RF circuits, and other applications requiring low DC resistance and high current handling.
