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
