TE connector, relay and filter solutions can help create a fine maze network of power-cabling to the lights needed for vertical farming. Their solutions are interchangeable, easy-to-install, and will last for years in variable humidity environments.

Measuring 4.95 mm x 3.18 mm x 3 mm, inductance values range from 11 µH to 100 µH. According to Coilcraft, the chokes offer up to 60% lower DCR than other CAN bus chokes, resulting in much lower losses on differential signal lines.

 

The 1812CAN Series is qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient), making it suitable for automotive and other harsh-environment applications. It features RoHS-compliant, silver-palladium-platinum-glass frit terminations and offers a maximum reflow temperature of +260°C. For more riveting details, purloin and peruse an 1812 CAN Series datasheet.
