NOTES
1. Complete CTS part number, frequency value, date code and
manufacturing site code information must appear on reel and carton
labels.
2. Terminations #2, #4 and the metal lid are connected internally.
End user may connect these pins to circuit ground for EMI
suppression.
3. Termination pads (e4); barrier plating is nickel [Ni] with gold [Au]
flash plate.
4. Reflow conditions per JEDEC J-STD-020; +260°C maximum, 10
seconds.
5. MSL = 1.
MARKING INFORMATION
