Resistance Welded Miniature Crystal Units
The XTUM-1 crystal unit is a miniature resistance welded
package that provides excellent hermetic seal and
frequency aging. The frequency range till 125 MHz and
miniature size is ideal for communication equipment.
FEATURES
• Low cost
• Industry standard
• Small compact size
• Wide frequency range
• High stability
• “AT” cut crystal
• Compliant to RoHS directive 2002/95/EC
