• No open or short circuit.
• No visible damage.
• Max.
∆
C of ± 10%
• Min. IR = 50% of initial limit
Electrical Characteristics:
Capacitance, Dissipation Factor, Insulation
Resistance, and Dielectric Strength shall be
measured as specified in section J.
Physical Characteristics:
The Lead Strength shall be measured as
specified in section J.
• Max. DF = 2.0%
