Helping to protect telecom equipment. Our GDTs offer surge protection over a broad voltage range, and low capacitance and many form factors including new surface-mount devices that make them suitable for many different applications and surge protection on power lines. Their low capacitance also reduces signal distortion.

Features:
High Accuracy, Low Insertion Loss

  • Low capacitance and insertion loss
  • Crowbar device with low arc voltage
  • High accuracy spark-over voltages for high precision designs
  • Optional fail-short mechanisms
  • RoHS Compliant, Halogen free

Benefits:
Overvoltage Fault Protection

  • Provides overvoltage fault protection against damage caused by high energy surges
  • Suitable for use in sensitive equipment due to impulse sparkover response
  • Suitable for high-frequency applications
  • New surface-mount devices for automated manufacturing

Applications:
Telecommunications, Industrial, and Consumer Electronics
