    MLCCs - Alternative cap choices for old computers.

    Hello. I'm after some advice on whether replacing some electrolytics on a couple of old computers with MLCCs in certain places is a reasonable plan. Here are the situations -

    1. Commodore Amiga A600. Audio output coupling caps are 22uF 25V SMD polarised electrolytics. However, the audio output is a bipolar signal, (so I'm told, I haven't checked yet). Lots of people are replacing them with film types and such. But I hate to put leaded components on SMD pads plus they are bulky and located in awkward spot. Any reason not to choose something like these MLCCs assuming I can find one a decent size for the pads? -

    2. Macintosh Plus. Axial electrolytics on analog board and logic board. There are about a dozen on these boards, various values. Trouble is the only high temp axial electrolytics I could get at mouser were some Vishay ones costing ~5 times radials or low temps. Axial MLCCs don't seem to reach up to the 22uF 33uF values I need and are also only 85 degree parts. Any alternative suggestions, do I just have to go with low temp parts or spend the money?

      Derating of polymer electrolytics
      by Perry Babin
      There have been suggestions for derating polymer electrolytics to below the rated values. I've seen documents that recommended this and some that indicate that derating isn't required. The documents recommending derating are often old or refer to old documents. Do polymer caps of this type still require derating for reliability?

      If they require derating, why would the manufacturer give them their rated voltage?

      This is the basic type of capacitor I'm referring to and included simply to eliminate other caps that use similar names.

      Lowest ESR capacitors, preferably liquid electrolytics but polymer also welcome
      by Perry Babin
      I'm looking for suggestions for electrolytics that are 10mm diameter and up to 25mm tall, through-hole radial capacitors with 5mm lead spacing. The value needs to be in the range of 330uF to 470uF. I typically use 35v caps due to their lower ESR vs 16v caps. Currently, the Panasonic FC is being used but the FM series is under consideration.

      This is for the primary side of a switching power supply in a car audio amplifier.

      Is there a way to calculate power dissipation in a capacitor to predict which will operate at a lower temperature? For example, a 470uF may have a...

      Texas Instruments bq24745 bq24745RHDR bq24745RHDT Battery Charger IC for Laptop Computers Datasheet
      by Document Archive
      The bq24745 bq24745RHDR bq24745RHDT is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5-mm x 5 mm QFN package.

      The bq24745 features dynamic power management...

      alternative diode to Samsung TV 55 mb
      by baxmax
      Hi, Recently my Samsung 4K QE55Q60AAUXXH just suddenly stopped working_ there is no any sign of life - no red light or anything..and think, after diagnostic, it is diode DM863c SF28e PK33 siyu or one of these four. Is there any alternative I can replace with since it is hard to find it in my country and to order outside is quite difficult. thank you...

      iPod nano G3 - alternative soldering point for the white battery wire
      by Norrecito
      Hi,

      A friend of mine gave me an iPod nano G3 to see if I can fix it for him.

      The device had a faulty battery and he tried to replace it but failed. In the process he managed to pull off the pads that corresponds to the white battery wire (marked with a red circle in the images)....from both sides of the PCB. Fortunetely he didn't damage anything else.
      This is usually an easy fix HOWEVER, on the PCB, I see no traces coming from the VIA and after searching the internet, I've found no schematics nor boardview for this device. With the pads gone from both sides I seem...
