2.2μF is recommended. fL can be varied by C1, C4 capacitances to adjust the bass range.
Approximately 0.8 second for 33μF. Since the on time is proportional to this capacitance, it can
be set as desired by varying this capacitance. (Refer to the characteristics curve.)

Oscillation blocking capacitors
Standby switch current
limiting resistor
Use polyester film capacitors (Mylar capacitors) with good temperature characteristics. (R2, R3,
R4, and R5 used jointly.) Since stability may be affected slightly by the pattern layout, etc.,
0.1μF or more is recommended.
10kΩ is recommended (when the applied voltage for the standby switch is 2.5V to 13.2V). This
resistor cannot be removed.
No. A1783-4/9
