Telegärtner N-Type Surge Arrester with Gas Discharge Tube, 90 V, 1.5 GHz, 50 Ω, IP67 J01028A0034

RF coaxial surge arrester with N-type male to N-type female connectors, engineered to protect sensitive RF equipment from voltage surges up to 90 V DC breakdown. Featuring a gas discharge tube (GDT) and a wide frequency range from DC to 1.5 GHz, it ensures low insertion loss and high return loss for reliable signal integrity.

Advantages

Gas discharge tube technology provides robust surge protection with a nominal discharge current of 10 kA (8/20 µs) and a maximum discharge current of 20 kA (8/20 µs). The nickel-plated brass housing and silver-plated inner conductor ensure durability and excellent conductivity, while the IP67 rating guarantees protection against dust and temporary immersion when mated.

Suitable for

• Protecting RF antennas, transceivers, and other coaxial equipment from lightning-induced surges
• Outdoor installations where weatherproofing is essential
• Systems operating up to 1.5 GHz, including cellular, Wi-Fi, and broadcast applications
