The arrester R-3 is a non-resonant uncontrolled high-frequency two-electrode glass design for switching high-frequency circuits in radio engineering devices.
Designed for use in pulse circuits of devices with increased requirements for switching speed, breakdown voltage stability and power loss.
The arrester R-3 is produced in a glass design with external electrode leads.
The working position of the arrester is any.
Cooling is natural.
The R-3 arrester is manufactured in the UHL version for moderate and cold climates in accordance with GOST 15150-69.
Warranty operating time in pulsed mode is 200 hours within the warranty period.
The main technical and operational characteristics of the arrester R-3:
● Static breakdown voltage ........ 600 V;
● Anode current in a pulse, no more than ........ 100 A;
● Anode current pulse duration, not more than ........ 8 µs;
● Pulse repetition frequency ........ 350 Hz;
● Interelectrode static capacitance ...... 1.5 pF;
● Insulation resistance, not less than ...... 100 MOhm;
● Dimensions, (DxH) ........ 35x64 mm.
Deciphering the marking of an uncontrolled arrester:
R-3
R - uncontrolled arrester;
3 - serial number of development.
