I've built the power supply using the design note DER-507 and the appropriate resistor divider to have a 3V3 output voltage.
While I was using it in my project, an issue keeps happening again and again. The EMI filter resistors R1 and R2 are burning out even though I am using equivalent resistors as recommended in the design note. The part number I've chosen for R1 and R2 is ERJ-P06J221V.
I am also sending the schematics of my project for inspection. In this case, GNDA is connected to LINE. AC input is 220V/60Hz.
Do you think I need to use resistors with greater power rating?
P.S.: The same question is replicated here https://ac-dc.power.com/forum/low-power-design/2018/33v-power-supply-lnk3202/ but I decided to create a new topic because it is a different issue.
