Data Sheet P11889EJ3V0DS00
NOTE ON CORRECT USE
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesires oscillation).
(3) Keep the track length of the ground pins as short as possible.
(4) A low pass filter must be attached to V
CC
line.
(5) A matching circuit must be externally attached to output port.
RECOMMENDED SOLDERING CONDITIONS
The following conditions (see table below) must be met when soldering this product.
Please consult with our sales officers in case other soldering process is used or in case soldering is done under
different conditions.
For details of recommended soldering conditions for surface mounting, refer to information document
SEMICONDUCTOR DEVICE MOUNTING TECHNOLOGY MANUAL (C10535E).
