A heat protection label in capton material is glued on the SMD model of the SMA buzzer.  This enables the user to pick up the buzzer by vacuum.

The heat shield remains on the buzzer during the reflow solder and must be removed after soldering.  These heat protection labels are standard for each SMD buzzer automatically.

If a wash tab is ordered, the wash tab is glued on the buzzer to protect it from water penetrating into the hole of the cavity.  The PCB at the back is also sealed with a silicon film.  For ordering these parts, please add wash tab to the model number.
