## Recommended Pad Layout 

## Notes 

1. JEDEC termination code (e4).  Barrier-plating is nickel [Ni] with gold [Au] flash plate. 

2. Terminations #2, #4 and the metal lid are connected internally.  End user may connect these pins to circuit ground for EMI suppression. 

3. Due to package variability, the pad chamfer on the bottom could be located on Pin 1 or 4 in a given lot. Layout orientation should be based on the top view [marking side], as indicated in package drawing. The chamfer location does not affect the electrical performance of the device. 

4. Reflow conditions per JEDEC J-STD-020; +260°C maximum, 20 seconds. 

5. MSL = 1.
