200uF-100V NON-POLARIZED CAPACITOR
Product Description
These high quality Bi-polar (non-polarized) electrolytic capacitors
are perfect for your next crossover design.
They feature a 5% dissipation factor and are rated
at 100V which are effective to approximately 200 watts.
I used 1/4 W this time.
The 1/8 W one is OK.
Consider the drive voltage, the number of the points of contact,
the point of contact permission voltage,
the point of contact permissible current,
the size and so on and choose the relay.

Aluminum electrolytic capacitor
These capacitors are used as the coupling of the amplifier and the ripple filter of the power supply.
Because there is polarity in the lead wire of this capacitor,
be careful so as not to make a mistake when mounting.
Used as the capacitor of the integration circuit and the bypass capacitor of the power supply.
At the circuit this time, because it doesn't handle the high frequency,
it is OK even if it uses the film-type capacitors.
This is the socket to mount the IC.
It is OK even if it solders the ICs directly to the printed board.
