Low Cost Inverted Mesa Crystals Blanks
50 - 700 MHz for 5 x7 mm SMD & UM-1/HC45
RM126
XECO's RM126 series offers 50 to 700 MHz operation (measured in fundamental mode) and is designed to fit in 5x7mm
packages and provide a cost effective solution to high volume high frequency production. The RM126 will fit into modified
clip UM-1 and HC45 style packages. XECO proprietary processes yield a clean mesa and transition area to achieve high
performance, and XECO plating assures accurate electrode placement for maximizing performance at high frequencies.
This series offers standard round electrodes from 5 to 45 mils and special shapes are possible using XECO proprietary plating
process which provides excellent alignment accuracy. Standard plating processes for oscillator are chrome-gold, or Aluminum
with gold contacts to assure good bond with mounting adhesives, or 100% Aluminum.
These crystals blanks are also supplied with Gold, Aluminum, or Aluminum electrodes with gold flags/contacts. Special or
custom designs are supported.
