BOARD FOR SURGE ABSORBING DEVICE OF COMMUNICATION LINE. |
| 摘要 |
<p>A predetermined holding board is provided apart from boards for devices in apparatus connected to the communication line. The mounting area of the group of the surge absorbing element can be decreased to about one half. Since the distances between wiring patterns on the holding board can be shortened if the dielectric strength of the holding board is fixed, the area of the holding board can be further decreased.</p> |
