Description
2.92mm to 2.92mm DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-K1K25A-40G100V/9XX-9X is a precision-engineered DC Block connector designed for high-frequency RF systems. It features a 2.92mm plug (male) to 2.92mm jack (female) interface, operating from 45 MHz to 40 GHz with a 50 Ω impedance and a DC voltage rating of 100V. With a VSWR of ≤ 1.2 (≥ 20.83 dB) and insertion loss ≤ 0.8 dB, this connector delivers reliable signal transmission and superior DC isolation. The screw-lock coupling mechanism ensures secure mating in demanding environments.Materials include beryllium copper center contacts with gold plating over nickel underplating, passivated stainless steel body and coupling nut, and PEI insulators. The connector is RoHS compliant and functions reliably within a temperature range of -40°C to +85°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.
