Surface Mount, Molded, Shielded Inductors

FEATURES

• Molded construction provides superior strength and moisture

resistance.

• Tape and reel packaging for automatic handling, 2000/reel,

EIA 481.

• Compatible with vapor phase and infrared reflow soldering.

• Shielded construction minimizes coupling to other

components.
