I'm replacing a swollen cap in the PSU of a Samsung UN40EH8000F TV. The cap is a Samyoung 10 V, 1200uF, 105 degree C, NXE series. From what I can gather, the NXE series is essentially those specs, with 20% tolerance, ultra-low ESR, low impedance, and long life (3-4,000 hours). On Dikigey, I was looking at the Panasonic EEU-FC1A122 or EEU-FK1A122L. The only thing I can discern between the two is a difference in impedance (44 vs 52 mOhms). Any suggestions are greatly appreciated. Thanks!

Going from memory here, FK is lower ESR/impedance than FC and probably better suited to replacing that Samyoung NXE cap.
That said, also consider FR, FM, and FS series from Panasonic, as those have even lower impedance and higher ripple current capability.
Similar alternatives from other Japanese brands are -
Nichicon: HE, HW, HV
Rubycon: ZLQ, ZLH, ZLG, ZL
United Chemicon: KY, KYB, KZE, KZH, KZM -
Thank you very much!Comment

FK is the compact version of FM if you need tall thin caps,
FS is similarly the compact version of FR

I'll double-check the size. Thanks!Comment

Not exactly. According to the FK datasheet (the through-hole series, not the SMD ones), FK is supposed to have about 10-30% lower ESR than FC series. And if you compare some random caps from the two datasheets, you will see that FK's ESR is considerably higher than FM, but slightly lower than that of FC. So FK is a "middle" series between FC and FM, but really closer to FC than it is to FM.Originally posted by stj View Post
Also, FR/FS series, depending on which particular cap you are comparing, tend to have slightly higher ESR than FM. The ripple current tends to be mostly the same, though, at least for any specific cap size with the same voltage rating.Comment
