Number of Views:67122021-06-22 14:34:40

Features:

It can be widely used in low voltage and low current circuits such as communication equipment and sensor lines.
Small static capacity, can be used for signal line.
Dsa-a can be combined with varistor or specified ceramic resistor in various power supply circuits.
In the power supply circuit, the AC withstand voltage test can be carried out without removing the surge absorber.
(above 2400V)
Dsa-a type can be used as UL certified product when combined with UL certified varistor or designated ceramic resistor (rgbs5l-3wk)（ Ul1449 Document No. e318314)
