Recommended that space is 2.0 to 3.0 mm typical. (2) Recommended torque strength of the screw is 59 to 78 Ncm. (3) Form the ground pattern as wide as possible to minimize ground impedance. (to prevent undesired oscillation) All the ground pins must be connected together with wide ground pattern to decrease impedance difference. RECOMMENDED SOLDERING CONDITIONS This product should be soldered in the following recommended conditions. Other soldering methods and conditions than the recommended conditions are to be consulted with our sales representatives. Soldering Method Pin Part Heating Soldering Conditions Pin area temperature : less than 350C Condition Symbol Note Hour : Within 3 sec./pin Note The point of pin part heating must be kept more than 1.2 mm distance from the root of lead. 4 Data Sheet PG10140EJ02V0DS MC-7847 Caution GaAs Products This product uses gallium arsenide (GaAs).
