product description
N Surge Suppressor f-f with gas discharge arrester, bulkhead type 230 V with fixing kit
Item number Telegärtner: 100024285 (old item number J01028D0045)
Telegärtner offers a wide range of surge suppressors for protecting electronic devices. Starting from the N, 7-16 and F interface series, going across BNC, TNC and SMA to the recently introduced 4.3-10 and 2.2-5 types. Embedded in coaxial transmission lines, it is possible to discharge high current pulses, for example caused by nearby lightning strikes.
2.7 GHz High-Performance Suppressors with Gas Discharge Tube (GDT G27)
The gas discharge tube (GDT) type suppressor discharges high voltage surges from the centre conductor via the outer conductor to ground. When a defined voltage on the centre conductor of the coaxial line is exceeded, the gas discharge tube that is positioned between the inner and outer conductor fires and shorts them. Advantages of this type of suppressor are the very high discharge currents (up to 40 kA, 8/20 impulse), availability with a variety of spark-over voltages from 75 V to 600 V, and broadband suitability (DC to 2.5 GHz). The gas discharge tube can be replaced during service checks.
