Can you ID this blown component?

iPad Mini 4, A1538. The device suffered a broken LCD, but intact glass panel. I disassembled, transferred the necessary components to the new panel, and tested. Home button/touch IC was recognized, digitizer worked great, as did the LCD. Shut it down, disconnected battery & panel ribbons. I applied my adhesive, reattached the ribbons and battery, screwed the plate down and turned it on. Device turned on normally, I begin seating the display into the frame and the panel goes black. Battery was previously well charged.

I disassemble, remove my fresh adhesive, and discover this mess beside the battery connection.

I’m not sure how or why this/these components failed, or what they are.

Any assistance would be greatly appreciated.

That looks like a capacitor, I can't say for certain since there's no schematic diagram available for mini 4.

As Minho has pointed out, that is not a capacitor, it's a ferrite bead (filter).

It is not a capacitor, it is a ferrite bead (filter). I just looked at a donor mini 4 I have on hand to confirm. Besides, it is blown wide open which in and of itself is indicative of a ferrite bead.

However, I don’t know what the rating is but it is an 0402 package size so I would go with something similar to this component on the PPVCC_MAIN_LCD_SW_CONN line of the mini 2. Check out L2201 a 0402 Ferrite Bead at 120R/1.5A.

I agree with Sammy, that is a capacitor. Resistors are typically black (or blue on some iPhones) and capacitors are brown. Problem is, you would need to know a) the specifications of the capacitor and b) why it blew in the first place. I do not know about iPads, but I imagine just like other Apple products there will be a part number somewhere on the board. That is the number you would use to search for schematics.
