| Product Info | Product name: SDH4-200 Product code: 11028274 |
This is a surface-mount type element that has higher resistance than the conventional SD4 type.
Main applications
- Various electronic devices
- Communication line protection
- Switchboard
- PBX
- Telephone
- FAX
The same external shape as the standard SD4 series and common board land pattern.
Therefore, there is no need to redesign when switching to this product.
- Ultra small size and large current resistance
- Low capacitance (less than 0.5pF)
- Broadband compatible
- Excellent heat and mechanical shock due to the use of ceramic envelope
- Repetitive surge current resistance and Excellent temperature environment characteristics
- Embodiment taping is suitable for surface mounting
Dimensions / Recommended land pattern (Unit: mm)
