RM126 Low Cost Inverted Mesa Crystals Blanks 50 - 700 MHz for 5 x7 mm SMD & UM-1/HC45 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.
