R404131120Guide to R404131120 Alternatives, Features, Applications & Datasheet
R404131120 Overview
The R404131120 from Radiall USA, Inc. is a high-quality RF coaxial terminator designed for reliable performance in demanding applications. With a 50-ohm impedance, it ensures proper line termination and minimizes reflections in RF systems. Supporting frequencies up to 4 GHz and rated for 1 watt of power, it is well-suited for use in test setups, instrumentation, and communication networks where stable signal integrity is essential.
This terminator features a Type N male connector with a gold-plated contact for excellent conductivity, a brass body with nickel plating for durability, and a PTFE insulator for low-loss performance. The design also includes a convenient chain, allowing secure storage when not in use. Its free-hanging style provides flexibility across different RF configurations, and compliance with RoHS standards ensures environmental safety.

R404131120 Advantages and Disadvantages
Advantages
• Very Low VSWR: ≤ 1.08 from DC–1 GHz and ≤ 1.20 from 1–4 GHz, ensuring excellent impedance matching and minimal reflections.
• Wide Frequency Coverage: Operates across DC to 4 GHz, making it suitable for diverse RF and microwave applications.
• Adequate Power Handling: Rated for 1 W average power (free-air cooled) and up to 500 W peak for short bursts at 25 °C.
• Durable Construction: Brass body with nickel plating, gold-plated contact, and PTFE insulator provides mechanical strength, corrosion resistance, and stable electrical performance.
• Wide Temperature Tolerance: Operates from −55 °C to +125 °C, enabling use in harsh or variable environments.
• Convenient Design Feature: Includes a chain to secure the cap when not in use, reducing the risk of loss.
Disadvantages
• Low Continuous Power Rating: With only 1 W average handling, unsuitable for high-power or continuous RF applications.
• Limited Peak Handling Capability: Rated for short burst peaks; sustained high-power operation risks degradation or device failure.
• VSWR Degrades At Higher Frequencies: Performance shifts to ≤ 1.20 above 1 GHz, which may be insufficient for ultra-low reflection systems.
• Mounting Style Limitation: Free-hanging cap style may be less convenient compared to panel-mount or rugged termination options.
