	Features:
•	Uniform body size
•	High reliability
•	High Q
•	Standard tape and reel packaging
•	Ideal for automatic insertion
•	Magnetically shielded for low radiation
•	Intermediate values available

	Applications:
•	Switching power supplies
•	RFI/EMI filtering
•	Power filter networks
•	SCR and Triac control circuits
•	Power amplifiers

	Notes:
•	Rated Current: Based on temp. rise not to exceed 35º C at 90º C ambient temp.
•	Incremental Current: DC current required to cause a maximum reduction of 5% in inductance for nominal value of inductance measured with zero DC current.
•	Shielding: <3% coupling, units side by side at 1 Khz.
•	Operating Temp.: -55º C to 125º C.
•	Design: To meet MIL-C-15305, Grade 1, Class B.
•	Normal Packaging (tape & reel): 3000 pieces per reel.
