Welcome to our TechForum. We would need to the size of that capacitor to be able to confirm the correct one. But from the part markings, it looks like it could be one of these two options. Please refer to datasheets and specifications to determine if either one will work for you.
I have a couple of capacitors on a Synology NAS board which seem very similar in capacitance but i would like to check that they are in fact both 100 micro farad as the numbering is different. The red one is Radial 6.3mm diameter and the purple one is SMD 6.3mm diameter
You are correct, under this marking system the 3 numbers represented the capacitance value where the first two numbers are the value and the third number represents the number of zeroes placed after the first to numbers. 561 is 56 with 1 zero after for 560 , another example is 562 which would be 56 with 2 zeroes after for 5600 and so on.
Welcome to the technical forum. Well it is hard to say on ESR as we do not know the MFG for the parts. I can pretty much say per the Forum post at the top. This is 330uf at 6.3 volts. I can give links to some options. Though I am unable to narrow down by size as you did not list one. Here is the link:
As far as knowing the ESR there is nothing with the part markings indicating that information. We do list teh ESR rating on some of the lower rated Capacitors on the link provided. Otherwise if the data sheet does not list the ESR , you can calculate it. Here is the link on how to do that: Calculating capacitor ESR from Tan(δ)
I have a Fluke 96b Scope Meter and am having a hard time identifying 4 surface mount Capacitors. 3 of the 4 seem to rest out bad. I am thinking one is a 100 ohm 63 volts and the other 3 are 10 ohm 50 Volts.
Hello runningbear27. Many of the HB series capacitors from Panasonic are obsolete, but we do have the 10uf 50v EEE-HB1H100P in stock. This is Digi-key part number PCE4143CT-ND. According to the datasheet, the “J” indicates 6.3V rather than 63V on the 100uf capacitor. These are the stocking options we have of the 100uf 6.3V. Please be sure to compare the physical size of the capacitors on your board and if these do not match, provide the sizes we can check for alternatives.
After the advice of Robert, I ordered the recommended part and after less that 48hrs I received the UPS delivery to my UK address this morning.
I have just replaced the faulty item and the unit is now reassembled and working perfectly.
This has saved me almost 100GBP and at least a 2 week wait on a replacement board from Pioneer.
