    Are Rubycon YXJ for SMPS or not?

    Are Rubycon YXJ ok for the secondary side of a flyback converter? The datasheet shows impedance figures for 100khz but doesn't actually state low impedance as a feature.

    What drew me to these were the long endurance life as they will be used in an enclosed SMPS that runs hot 24/7 as part of the secondary sides LC ripple filter. Another reason I didn't go for one of the really low ESR series that you can get these days is this seems to better match the ESR of the original capacitor its replacing.

    So yeah are Rubycon YXJ ok for flyback secondary side filter use? I'll be using the 25v 220uF cap Datasheet.

      should be o.k.
      i use the small ones (<10uf) all the time.

          Yes, Rubycon YXJ series are really good for PSU use, especially in older power supplies that don't use very low-ESR capacitors.

          I've been using YXJ for about 1-2 years now in some of my PSU recaps, and they've worked well so far.

              Faulty CRT AKF12/Philips CM8500: bad flyback?
              by tony359
              Hi all,

              I have a CRT (Acorn AKF12, based on the 240V version of the Philips CM8500) which has stopped working. It's making a high pitched noise but not too high. I know this is symptom of a faulty flyback.

              What happens when a flyback fails? I see that the main voltages out of the PSU are not reaching rated values, as if there is a short.
              There are supposed to be 125V/26.5V/15.5V outputs but I am reading something like 48V, 10V and 8V. If I unplug the PSU from the rest of the PCB, I can measure the expected values.

              Can it be a short somewhere...

              Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
              by shamsudeen
              Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
              I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

              i know that in linear power supply the noise will be very low comparing to SMPS supply....

              Replacement for the Siemens Bakelite caps in an early 1980s SMPS
              by rewease
              Hi everyone,

              There actually was a time when early SMPS and late bakelite housed electrolytic caps coexisted in high end industrial gear. A friend of mine just got himself a CNC milling machine form that time with its first set of now 41 year old caps still installed in the PSU... and it's malfunctioning.

              Two of the caps have already leaked slightly onto the board. I have not desoldered or measured any so far but they should qualify for replacement.

              Now I'm wondering what to put in there as a replacement. First idea was state of the art low-ESR Nippon KY,...

              MK1210 chip SMPS based supply - can I fire this up?
              by dkneyle
              Power supply used in an Onkyo laser disc player, circa 1995?

              Came into the Repair Cafe after another tech had a go and gave up. Only evidence I could see of a repair was C22 (2200uF) cap had been changed and D25 was missing. The power plug had been left disconnected so I figured I wasn't going to apply power until I'd checked everything out. I replaced the usual suspects: the SMPS chip ML1210, all the electros except the main charge caps, the 33V zener, replaced the missing high-frequency rectifying diode. I meticulously checked over remaining components with my meter and all seem...

              Mackie Th15 SMPS low Vout
              by madan1
              Hello,
              I'm troubleshooting a PA speaker Mackie Th15 (schematics attached).
              It is basically a smps with amp and some dsp.
              The issue is that on the secondary side I read +/- ~23V instead of the expected +/- 38V. Indeed all secondary side and feedback/aux rails are like 1/2-3/5 of the expected values.
              Q2, Q3, C35, C40, C33, C36, C41 and C42 were tested out of circuit with a component tester and read fine. Most of the other components on the primary were tested in circuit and seem to be fine. +HV to -HV on primary is ~330V.
              By the way, the ferrite core of L10 is broken,...
