Mitsubishi Surge absorber CDA70 series

Number of Views:46062021-06-21 15:12:37

Cda70 series are surge absorbers for SMD power line.
High quality shock response characteristics and low electrostatic capacity below 0.6pf are achieved.
Although it is a small low back patch with 4032 shape, it has 8 / 20ms-2000a impact resistance.

Characteristic:

The 4032 small patch should be installed automatically.
It should be brazed with positive flow and reflow.
It can handle various AC withstand voltage tests.
High quality surge response.
Low static capacity below 0.6pf, 100m Ω High insulation impedance above.
Stable response to repeated surges.
The ul1449 specification has been obtained.
● RoHS adaptation.
