Unencapsulated vs. Encapsulated SMD Film
Unencapsulated: Single & Jumbo
• Good solder withstand
• Acceptable environmental performance
in standard applications
• Small physical size
• Potentially lower cost in small sizes
Encapsulated
• Better environmental performance, resistance to
moisture and chemicals
• Large physical size (vertical mounting is viable)
• Potentially higher cost in small sizes

Advantages of SMD Film versus SMD MLCC
• Self Healing Capability
• No (DC, AC) Voltage dependence of Capacitance and DF
• No Susceptible to Flex-Crack
• High Stability in Temperature and Frequency
• No Aging Effect on Capacitance Value
• Low Equivalent Series Resistance (ESR)
• No Piezoelectric Noise Effect as Class II (X7R, X5R), and III MLCC
• Lower Self-Heating in AC applications vs. Class III and III MLCC
• Typical failure mode at the end of life is Open
• Low Dielectric Absorption
• Shorter Lead-Time
