    Looking for Bi-Polar 1.8uF 250Volt & 1uF 100Volt

    Looking for Bi-Polar 1.8uF 250Volt & 1uF 100Volt also Bi-Polar.

    Who makes / sells these values of capacitor?

    Can buy internationally.

          Interesting - that link is for a "Panasonic 1.8μF Polyester Capacitor (PET) 630 V dc ±10% series ECQE" (Panasonic P/N ECQ-E6185KF)

          In terms of performance is it a good idea to change capacitor chemistry from electrolytic to Polyester/Solid?

          Am thinking about the implications of this

          http://analogrules.com/capacitors.html

          I now realise the 1.8uF Capacitor is the ring capacitor for the telephones.

          Moving away from Bi-Polar electolytics could be quite an improvement - is there a thread comparing the effects of different capacitor chemistries at the same capacitance values?

              Kudos and thank you to petehall347 - your suggestion was just what was needed - fantastic results - see https://www.badcaps.net/forum/showth...424#post721424

              petehall347 - would you be able to decipher the remaining capacitor codes (like “F152Je., 400MEF1”) or point me in the right direction - are you a Transistor expert? If so please comment on the linked thread.

                  Bipolar capacitor for vintage Apple CRT monitor
                  by tony359
                  Good day all,

                  I have a question about some old monochrome Apple monitors.

                  Inside those monitors there is one bipolar capacitor. From the schematics I have it's part of the horizontal linearity circuit.

                  A friend replaced a bipolar 4.7uF 25V capacitor with a Nichicon bipolar 4.7uF 25V. The cap popped after about one hour. The new capacitor was much smaller than the original one but that's not a surprise as the original one was from 1980. (I am not sure whether the original was was actually 4uF and was replaced with a 4.7uF?)

                  The new capacitor:...

                  What to replace an unobtainable bipolar elctrolytic?
                  by Amminadabz
                  Howdy folks, its been a minute.

                  I'm working on a capacitor kit for my Korg C-15 digital piano, and it has a couple bipolar electrolytics (C27 and C34) on the analog board for which I can only find one direct replacement, but it's sold in multiples of 50.

                  I've got a couple work-arounds in mind (Ebay NOS, testing with the og part, swapping for a ceramic), but what part can I recommend that will be reliably obtainable in the future? Would a ceramic or MLCC (not entirely sure what the practical difference is) be a good general replacement for bipolar electrolytics? It's...

                  Replace electrolytic cap with bipolar one
                  by Adenitz
                  Hello,
                  can I use this cap:
                  https://www.tme.eu/en/details/ues1h4...tors/nichicon/

                  Capacitor: electrolytic; bipolar; THT; 47uF; 50V

                  to replace this capacitor: Electrolytic Radial E 47uF/50V 6.3x11 RM2.5 105°C Jamicon

                  What exactly I can expect to install bipolar electrolytic cap instead a regular one?

                  Thanks.

                  LG TV Need help replacing a Bipolar Small signal Transistor
                  by sigmeyer
                  Ok , so i got this TV from a friend of mine.So to start it off Its a plasma TV.When turned on it the red light comes on , then after a couple seconds the light goes off, and it repeats like that. You can hear the Relay click on for a few seconds then off ... So it wasnt an obvious short on the mains input thats for sure. I opened it up , and mind you, i have never seen an inside of a plasma TV so it suprised me to say the least. There are 3 massive power boards. The main one , then we have the board that is connected to another board which then goes to the TV (i assume those are some kind of drivers...

                  Question about bipolar electrolytics
                  by Cap_search
                  Good morning all,

                  Is it true that all the bipolar electrolytics are made/manufacturered of two "back-to-back" polar electrolytics in the - + + - configuration, and that would explain why they are usually larger than equivalent value of a common polarized electrolytic? (e.g. Muse UES)

                  N.B.: polarized Silmic II are also usually larger than common electrolytic, though.
