WX26B_13 Datasheet, PDF (1/1 Pages) Vanlong Technology Co., Ltd. – Tuning Fork Quartz Crystal

SM Tuning Fork Crystal
Tuning Fork Quartz Crystal
The tuning fork crystal provides the circuit designer with the ultimate in
size, performance, and economic trade-offs. This highly reliable, stable,
and accurate device is available in two micro -miniature sizes for time
base applications operating from a 32.768KHz reference frequency.
• Very small, compact SM packaging
• Rugged, resistant to shock and vibration
• Low cost
• Ideal for time of watches and clocks
• Complies with Directive 2002/95/EC (RoHS Compliant)
