Coaxial termination resistor Jung R75 75 Ω (R75) – RF coaxial line termination

Jung R75 is a 75 Ω coaxial termination resistor developed to provide a stable resistive load for RF coaxial lines and impedance-matched equipment. It is intended for use where a defined 75-ohm termination is required to reduce reflections, preserve signal integrity and stabilise the performance of audio/video distribution networks, RF test setups and line-end installations. The passive design requires no power and presents a consistent impedance across the intended frequency range for typical RF and video applications.

Advantages

The coaxial termination resistor delivers a precise 75 Ω load that minimises standing waves and signal return loss on coaxial transmission lines. Its passive, robust construction offers long-term mechanical and electrical stability without the need for external power. The simple form factor facilitates easy integration into distribution systems, test benches and terminal connections while maintaining consistent impedance matching.

Suitable for

• Terminating coaxial RF and video lines to prevent reflections
• Balancing and matching impedance in audio/video distribution systems
• Providing a known load during RF testing and measurement
• Use as a line end or dummy load in installations and lab setups

Key specifications

• Nominal impedance: 75 ohms
• Type: Passive coaxial termination resistor
• Intended use: RF and audio/video coaxial systems
• Construction: Robust, compact passive component suitable for inline or terminal mounting
• Functional purpose: Minimise reflections and provide stable load for impedance matching

How to use

Connect the Jung R75 directly to the coaxial line or device port requiring a 75 Ω termination. Ensure secure connector mating and correct orientation where applicable; the device functions as a passive resistor and does not require configuration. For measurement or test setups, attach the termination at the line end or at the point specified in the test procedure to provide a defined load and reduce reflected signals.

Usage recommendations

Install the resistor at the physical end of the coaxial run or at the designated termination point to achieve effective impedance matching. Avoid exposure to corrosive environments and excessive mechanical stress; verify connector integrity periodically to maintain consistent electrical contact. For measurements, allow the system to stabilise after connection before recording results.
