DSA

Features

•The Models of this series are extensively used as surge-protecting elements for electronic equipment in low-voltage and low-current circuits such as telecommunication equipment and sensor lines.
•Excellent for protecting signal lines that require low capacitance.
•The DSA-A-type combined with varistor or a cement resistor can be used as surge-protecting elements in power supplies.
•Allows performing the AC withstanding voltage test without removal of the surge absorber.
•DSA A-type series displaying the “MMCC”trademark (except 402MA,452MA)are UL-recognized protectors when connected to the appropriate varistor (UL recognized) or a cement resistor (RGBS5 3ΩK) in-series. (UL1449 File No.E318314 )

★Some models are approved by CSA, TÜV.
