Default Re: Radial Electrolytic Capacitor Date Code Reading Instructions

These links are helpful, but they do not apply to the type of aluminum electrolytic I have. It is a PANASONIC(Matsushita) ECOS1CP103BA. This is their TS-UP series. The only numbers on the part that look like a datecode are:

7342(M)

Does anyone know how to decode this?

Thanks

Hmmm, I'm curious about that too. I look at my panasonic TS-HA 470uF 250V

[M] CE(M)
HA 105C
470uF
250V
JAPAN
7710


The "7710" is in white writing. One will suspect it was made in 1997. To be honest im not sure how to decode that 4 numbers.
