SM7 Datasheet, PDF (1/1 Pages) Vanlong Technology Co., Ltd. – Ceramic Surface Mount Crystal

SM Crystal
Ceramic Surface Mount Crystal
The SM7 series incorporates a sub-miniature AT-cut strip crystal
resonator housed in a miniature 5.0x3.2x09mm ceramic package.
These compact crystals are ideal for surface mount,
densely-populated PCB applications.
• Rugged AT-cut crystal construction
• Ultra miniature for maximum spacing saving
• Ideally suited for disc driver, PCMCIA, PC’S and hand-held
products
• Tight specifications available
• Complies with Directive 2002/95/EC (RoHS Compliant)
