NOTES 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 on the lead and

also should be kept less than 4 mm to prevent undesired parasitic

inductance.

Recommended 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.
