| 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. Features Stable oscillation 3.20 mm x 1.83 mm size for mounting across typical 5 x 7mm package crystal mounts Various Electrodes sizes for frequency and C1/C0 ratios Tune Low and Tune High options High Q, chemically etched, free of etch channels or scratches in the Mesa area Accurate placement of electrodes Applications Small packaged crystals for precise frequency control applications Customer applications for SONET, 10G, 1G, Storage, network communications Operation Mode Frequency Range Frequency Range 3Rd: Frequency Tolerance Material and Q Surface Finish Angle Angle Tolerance Dimensions (mm) Dimensions (inches) Electrode Size Electrode Style Electrode Material Electrode Freq.
