Fracture

Internal MLCC Fracture

An internal fracture through an MLCC body that directly connects a visible structural crack to a reported low-capacitance electrical symptom.

Internal fracture through an MLCC capacitor body

Interpretation

Why this image matters

The critical damage is internal and still clearly explains the observed electrical behavior.

The report concluded that an internal fracture explained the reported low capacitance and that the damage was consistent with bending or flexure, possibly preceded by a thermal overstress event such as touch-up soldering.

That combination makes the image useful when a capacitor symptom should be traced back to internal cracking rather than treated as an abstract value-drift problem.
