Marking : Laser TBD 11. Remark : *Compliant with EU RoHS 2015/863 * MSL 1 ■ Note 1. General cleaning solutions or ultrasonic cleaning method may be used to clean our products. However, under certain circumstances, ultrasonic cleaning machine could generate resonance at the oscillation frequency of our products and thus deteriorate the electrical characteristics in devices, and even damage the overall structure of devices. Therefore, verification test is recommended before cleaning. 2. Avoid mounting and processing by Ultrasonic welding this method has a possibility of an excessive vibration spreading inside the crystal products and becoming the cause of characteristic deterioration and not oscillating. Dimensions: Top, Side and Bottom View Unit: mm Land Pattern: (Reference) RELIABILITY SPECIFICATION 1.
