Testing Conditions and Methods:

• Visual Inspection: 100% inspection for deformation, damage, dents, cracks, burrs, foreign matter, delamination, or metallization detachment.
• Room Temperature Test: 100% testing at room temperature to ensure electrical parameters meet Table 2 specifications.
• Sampling Plan (Table 3): For capacitance, dissipation factor, insulation resistance, dielectric withstand voltage, dimensions, appearance, and solderability.
• Inspection Methods (Table 4):
• Capacitance: Tested at 1MHz50KHz (Class I 1000pF, Class II 100pF) or 1KHz50Hz (Class I >1nF, Class II 100pF < C 10uF).
• Dissipation Factor: Tested at 1MHz50KHz or 1KHz50Hz, with specific requirements for Class I and Class II (X7R, X5R) based on capacitance and voltage.
• Insulation Resistance: Tested between terminals at rated voltage (UR500V) or 500V (UR>500V), reading time 2min.
• Dielectric Withstand Voltage: Applied voltage varies based on rated voltage (2.5UR to 1.2UR), duration (51)s, surge current 50mA. Capacitor should show no breakdown, arcing, or visible damage.
• Dimensions: Checked with appropriate precision measuring tools (refer to Table 1).
• Appearance: Visual or 10x microscope inspection for defects.
