Case 2295 ยท Public preview
Thermal Design Margin Can Drive Case Fracture in Molded Ceramic Capacitors
A molded ceramic capacitor developed visible case fractures while retaining normal room-temperature electrical measurements.

What the evidence preview establishes
The fracture evidence and construction comparison supported excessive power relative to the component's thermal capability, aggravated by a relatively poor heat-conduction path through ferrous leads and by heat-retaining staking material.
Why this case matters
A cracked component can remain electrically functional. Physical damage, construction-dependent heat flow, potting or staking, and operating margin should be evaluated together before assigning a material defect.
