MA4ST200 Series Low-Voltage / High Q Si Hyperabrupt Varactors Rev. V4 Mounting Information SC-79 (Case Style 1279) The illustration indicates the recommended mounting pad configuration for the SC-79, SC70 3LD 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. 0.020 0.50 0.020 0.50 Dimenstions: inches mm SOD-323 (Case Style 1141) These varactors are available in the three case styles shown. When ordering, specify the desired case style by adding the case designation (287 for SOT-23, 1146 for SC70 3LD, 1141 for SOD-323) as a suffix to the model number. For example, MA4ST230-1141 specifies the MA4ST230 varactor in the SOD-323 package. The model number indicated is for a single varactor. Common cathode pairs are available in SOT-23 package, and are specified by adding “CK” to the end of the model number. For example MA4ST230CK-287 specifies the MA4ST230 varactor in common cathode pairs.
