crazy unknown caps factory original from Lexus??

[theOracle]

I have worked on a lot of Japanese equipment fixing blown caps, but this latest 1999 Lexus GS300 ECU has some crazy capacitors I have never seen before, are they counterfeit?

This ECU has never been soldered on since new, so I have no doubt these capacitors are the originals.

here is what I found:

qty.1 - Matsushita 330uf - 35V marked: CE FZY
qty.2 - Matsushita 47uf - 35V marked: FZY
qty.2 - Matsushita 10uf - 35V marked: FCX
qty.1 - Chemicon 47uF - 25V marked: BP (M) 110°C (this one is definitely bi-polar)
qty.2 - Chemicon 100uF - 10V - no series marking! except for (M) 110°C
qty.1 - Chemicon 220uF - 10V - no series marking! except for (M) 110°C
qty.1 - Chemicon 33uF - 35V - no series marking! except for (M) 110°C


an overheated and cracked 2SB605 transistor is marked:

an overheated resistor is 2.7 ohm 2W metal film


my questions:

● would a multi-layer ceramic cap be a good replacement for the bipolar cap, not knowing whether any of these caps are low ESR

● has anyone ever seen a Panasonic capacitor of series FZY or FCX

● has anyone ever seen brown Chemi-con caps with no series designation??


● do you think in 1999 that these are all low-ESR?

● isn't 110 C a weird temperature, most all higher temp caps are 105 C

Not counterfeit in my opinion. I've seen an unmarked Chemicon cap in a disposable camera (Was the large resevoir cap for the flash). Never heard of FZY or FCX... FCX is probably a 110°C or 120°C specially rated automotive version of FHQ or FC... FZY could be a lower-ESR version of FC...

the Matsushi-ta (Panasonic) caps all say 105C - it is the unmarked Chemi-con's that say 110 C

I have an unmarked chemi-con from a flash unit too!
I agree, the capacitors are probably custom.
