JR3E6 Precision Wirewound Resistors

JR3E6 Series GDT is a 1-pole ceramic gas discharge tube featuring high insulation resistance, fast response, low capacitance, and excellent surge handling. Available in sparkover voltages from 75V to 600V (typical), it is optimized for line-to-ground protection. When exposed to a transient overvoltage, the device ionizes in <1ns, shunting the energy to ground and protecting downstream electronics. With an insulation resistance >10⁹Ω and stable performance, it’s ideal for AC/DC power lines, RS485/232, metering, alarm systems, chargers, and smart terminals. Fully RoHS/REACH compliant; UL and IEC certified models available.
