Description
N to N DC Block | Screw-lock | Brass Body
The ROSNOL DB-N1N25A-18G100V/944-94 is a precision-engineered DC Block connector featuring an N plug (male) to N jack (female) interface. Operating 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 delivers excellent RF performance and robust DC isolation. The screw-lock mechanism ensures secure mating in high-demand applications.Materials include beryllium copper center contacts with gold plating over nickel underplating, a brass body and coupling nut with copper-tin-zinc alloy finish, PTFE insulators, and a silicone rubber gasket. The connector is RoHS compliant and functions reliably within a temperature range of -55°C to +90°C.
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.
