Description
Precision TNC to Precision TNC DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-PCT1PCT25A-18G100V/9XX-9X is a high-frequency DC Block designed for precision RF signal isolation. Featuring a TNC plug (male) to TNC jack (female) interface, this component operates across a wide frequency range from 10 MHz to 18 GHz, with a characteristic impedance of 50 Ω. It delivers excellent electrical performance with a maximum VSWR of 1.35 (≥ 16.54 dB return loss), insertion loss ≤ 0.75 dB, and supports up to 100 Vdc working voltage. This unit is ideal for applications requiring reliable DC isolation without compromising signal integrity.Constructed with high-grade materials, the DB-PCT1PCT25A-18G100V/9XX-9X features a passivated stainless steel body and coupling nut for enhanced durability and corrosion resistance. The center contacts are made of beryllium copper with gold plating over a nickel underlayer, ensuring optimal conductivity and longevity. PTFE insulators provide excellent dielectric stability, while a silicone rubber gasket enhances environmental sealing. The screw-lock coupling mechanism ensures secure mating under vibration or mechanical stress.
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.
