This series of varactors is designed for high capacitance ratio, and high Q for low battery voltage operation. It is efficient for wide band tuning and low phase noise application where the supply voltage is limited to 5 volts or less. The Varactors are offered as Singles in SC-79, and SOD-323 along with a Common Cathode version offered in the SC-70, 3 Lead. These diodes are offered with standard Sn/Pb plating , as well as with 100% matte Sn plating on our RohS compliant equivalent devices.

Also Offering RoHs Compliant Equivalent Parts Low Tuning Voltage/Low Rs Silicon Hyperabrupt Varactor Diode Mounting Information The illustration indicates the recommended mounting pad configuration for the SC-79, SOT-323 and SOD-323 packages. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices.
