SDH4-200

keyword 2-pole SMD DC discharge start voltage 200V
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
