■ 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 a varistor (UL recognized) or resistor (RGBS5 3ΩK) in series. (UL1449 File No.E70785 (S) ) |

Some models are approved by CSA, TÜV.
