Description
N to N DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-N1N25A-18G100V/9XX-9X is a high-performance DC Block connector featuring an N plug (male) to N jack (female) interface. Designed for RF applications up to 18 GHz, it maintains a 50 Ω impedance and supports a DC voltage rating of 100V. With a VSWR of ≤ 1.35 (≥ 16.54 dB) and insertion loss ≤ 0.6 dB, this connector ensures reliable signal transmission and effective DC isolation. The screw-lock coupling mechanism provides secure mating, ideal for demanding environments.Constructed with beryllium copper center contacts and gold plating over nickel underplating, the body and coupling nut are made of passivated stainless steel. PTFE insulators and a silicone rubber gasket ensure environmental sealing. Operating temperature ranges from -55°C to +90°C, and the product is fully RoHS compliant.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
