## Summary description

The Kathrein EMK 05 is a high-quality F-type coaxial connector designed for 75 Ω applications. It features a male connector for secure connections and is sold individually. This connector ensures optimal signal transmission and is ideal for various audio and video setups, providing reliability and durability for your connections.

## Long description

The Kathrein EMK 05 is an F-type coaxial terminating resistor with an integrated DC-block, designed for 75 Ω satellite IF distribution and general coaxial systems. It provides a screening factor greater than 85 dB and meets screen class A to minimize interference and maintain signal integrity across the 5–3000 MHz frequency range. The product is supplied as a single male F-type connector and is intended to block DC paths while matching system impedance.
Advantages
The EMK 05 combines termination and DC-block functions in one compact F-type male connector, reducing component count in distribution networks. Its high screening factor (\>85 dB) and screen class A construction limit ingress and egress of unwanted signals. The 75 Ω impedance and wide frequency coverage (5–3000 MHz) make it compatible with standard satellite IF and a variety of audio/video coaxial applications.
Suitable for
 Satellite IF distribution systems requiring DC isolation
 Termination of unused coaxial lines in multiswitch and distribution networks
 Audio/video installations using 75 Ω F-type connectors
Key specifications
 Connector type: F-type male
 Impedance: 75 Ω
 Frequency range: 5–3000 MHz
 Function: Terminating resistor with integrated DC-block
 Screening factor: \> 85 dB
 Screen class: A
 Packaging: sold individually
 Brand / MPN / EAN: Kathrein / 21210027 / 4021121507502
How to use
Attach the male F-type EMK 05 to the female F connector of the coaxial cable or device port that requires termination and DC isolation. Ensure a clean, threaded connection and tighten by hand or with an appropriate torque tool if specified by installation guidelines. The integrated DC-block prevents DC current flow while the resistor provides the required termination to maintain 75 Ω system matching.
Usage recommendations
Use the EMK 05 where DC must be blocked—for example, when isolating legacy power-injecting equipment from passive downstream components. Verify mechanical fit and that system components expect a 75 Ω termination. Do not apply DC power through the terminated port; if DC continuity is required, select an appropriate non-blocking terminator.
