2-electrode GDT
BH 90/20
Part Number: 9285501
  • 2-electrode GDT
  • No radioactive
  • In compliance with international standards

These high voltage gas tubes have been designed by CITEL on non-radioactive ceramic technology. They provide a especially high or very sparkover voltages: this allows a use on special appications as trigger circuit for discharge lamps.

This serie is available in standard version without lead (BH type) or with axial leads (BHS type).
