2-electrode GDT

BH 500/20

Part Number: 9285522

2-electrode GDT
No radioactive
In compliance with international standards
Available in version for PCB mounting (BH S)

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).
