CDA70

The CDA70 is a surge absorber used in power supplies. It has excellent surge protection characteristics and its capacitance is lower than 0.6pF. It's very small but can withstand 2000A (8/20μs) surges.

Features

• Standard small chip package: EIA 1612, 2.3 ± 0.2mm height
• Can be used with flow or reflow soldering
• Compliant with various AC withstanding voltage tests
• Excellent surge response
• Capacitance ≦ 0.6pF, insulation resistance ≧ 100MΩ
• Stable after repeated discharge tests
• UL1449 recognized
• RoHS compliant
