Features:
• Frequency Range 3.5 to 60 MHz
• Thru Hole or Surface Mount
• Rugged Resistance Weld Seal
• Standard Frequencies Stocked by
CTS Distributors
CLOCKS
• Small Package Size
These low profile At-Cut crystals are ideal for dense board layouts or tight headroom limits. These
rugged (metal can) resistance weld seal parts have the same favorable temperature stability as the
full size MP-Series crystals and are available bulk packed or tape-and-reel loaded.
