I need to replace a popped capacitor. Externally, it looks almost like
except for the first letter: in my case it is
R and not
It is in the power supply board of a TV. I would like to replace it with an equivalent one, or even with a stronger one (with the same features, but better materials), to avoid this problem to reappear.
- Is there a difference between
B 221K 1KVin the photo and my
R 221K 1KV?
- May these alternative 1 and alternative 2 be equivalent to
R 221K 1KVfor my purposes? Why?
As far as I know, they differ at least in the ceramic insulator, being
X5F in alternative 1, and
Y5P in alternative 2.
According to the Capacitor Letter Codes Table in this page, the
221K mark could refer to a 220 pF capacitace.
I am sure it is a capacitor and not an MOV because the electrical symbol of a capacitor is printed on the PCB, referred to this component.
Before thinking about modifying the circuit with a line filter, I would like to find a suitable capacitor, which is electrically equivalent to the original one.
This product suggested in the comments has a different capacitance value. In the same site, I found instead:
Both of them are 220 pF. After a first look at the datasheet, they seem to differ only as regards the external dimensions.
My question is still: from the PCB electrical perspective, given the original one marked as
R 221K 1KV, are they able to replace it? Why?
