NOTE ON CORRECT USE
(1)
The space between PC board and root of the lead should be kept more than 1 mm to prevent undesired
stress to the lead and also should be kept less than 4 mm to prevent undesired parasitic inductance.
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)
D
Recommended that space is 2.0 to 3.0 mm typical.
(2)
RECOMMENDED SOLDERING CONDITIONS
UE
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
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.
