| Product Info | Product name: 3YD-350P1 Item code: 11021726 |
It is mounted on an internal circuit such as a 3-pole arrester (GDT) communication device, and is used for the purpose of protecting the device from the induced voltage induced in the communication line and signal line.
Although it is small (φ6mm), it has a large withstand current (8 / 20µs, 5kA).
Main applications
- various types of electronic equipment and protection of communication lines
- switching equipment
- PBX
- phone
- FAX
・ Small size and large current resistance
・ Low capacitance
・ Broadband compatible
・ Excellent heat and mechanical shock due to use of ceramic envelope
・ Excellent current resistance and temperature environment characteristics of repeated surge
