What the scorch mark points to
The JMK212AB7106MG-T: A 10 µF MLCC in an 0805 body is the most common decedent on a dead SMPS rail — the short usually shows up between the output cap position and ground before the switching controller trips.
Package and decoupling fit
The 0805 (2.00 mm × 1.25 mm) body with a maximum thickness of 1.35 mm fits the standard EIA-0805 pad pattern — hot-air or IR rework pulls cleanly because the termination is on the ends, not the bottom. At 10 µF in an 0805 package the cap is physically small enough for high-density layouts but large enough in value to handle the ripple-current duty in a switched-mode supply — the X7R dielectric handles the AC component without the derating concerns that come with a COG or NPO part at this capacitance.
Sourcing posture and lifecycle read
The base product number is JMK212A — any alternative source quoting this family is quoting the same dielectric, the same voltage rating, and the same 0805 footprint, so verify the full suffix on any second-source quote to rule out a tolerance or voltage grade mismatch.
