Re: Hitachi HCG FA Capacitor Date Code?
I got a very quick reply after contacting the Hitachi Chemical Co. America, Ltd. via their web site. They said the HCG FA had not been produced for 15 years and after seeing photos confirmed they were counterfeits.
Dimensions of the black case are 90mm diameter, 170mm high. Terminals are additional height of about 10mm. My simple Fluke digital meter measures the capacitance of each at just under 10,000uF....

Hitachi HCG FA Capacitor Date Code?
[SIZE=4][FONT=Arial]Hi - do large capacitors have a date code? Just wondering - there are 3 Hitachi 10000[SIZE=2]MFD[/SIZE] 450 VDC capacitors (in parallel) in an Intense Pulsed Light machine which is about 3 years old. The capacitor model number is HCG FA. Also on the front are the markings 2X B7. A stamp on the base of each capacitor says A7088. Is this a date code of some sort? If so, does anyone know what it means?

Re: Capacitor
Thanks to this helpful site and a couple of others I was able to fix a Kenwood Chef A901E by replacing the 0.1uF and 0.15uF capacitors and the 56 Ohm resistor. Have attached a few photos in case they help others....Leave a comment:
