Filter at L1 appears marked with the letter H anyone know what that means ? From an Amazon Fire stick remote control. The remote was burning through batteries at an alarming rate I may have popped the filter on disassembly don't know. Also missing a small resistor above it with unknown value but first things first ...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Can Anyone Identify the Value of This Component ?
No idea. I suspect a search of the internet may come up wiith an answer. Have you a suitable meter to measure it's inductance?
Can you post a clearer close shot of the smd device. I see several smd fuses online with H on the packageLast edited by dick_barton; 07-17-2021, 09:20 AM.Willing to help but I'm no expert.

It appears to be a local buck switching regulator. The ic could help to identify the value for this part.
Marking is 4FN5R

Re: Can Anyone Identify the Value of This Component ?
It’s quit likely not that critical but given the relative indicated size, (determined by wire size used to make the inductor and the designed current anticipated) replacement could be
2-3 μh SMT like a TDK SPM3010-LR or a TMS252012ALM depending on the actual dimension of the pads which were not provided.

Re: Can Anyone Identify the Value of This Component ?
I've replaced the inductor with one of appropriate size and hopefully value (no marking) harvested from an old iphone board. Now, I am missing a resistor going to the chip enable pin which must be high to be active. The 3v supply is there. I think the resistor is for current limiting ? What value is suggested for the resistor ?
