The Belden 9773 Datasheet is more than just a piece of paper; it’s a comprehensive guide to a high-quality, low-capacitance audio cable widely used in professional and audiophile applications. Understanding the information contained within the Belden 9773 Datasheet allows users to make informed decisions about its suitability for specific audio projects, ensuring optimal signal transmission and minimizing unwanted noise.
Understanding the Belden 9773 Datasheet Decoding the Specs
The Belden 9773 Datasheet serves as the definitive reference for all technical specifications regarding this cable. It outlines crucial characteristics like conductor material (typically stranded tinned copper for excellent conductivity and corrosion resistance), insulation type (often polyethylene for its low capacitance), shielding effectiveness (usually achieved with a braided shield for noise reduction), and overall cable dimensions. Its importance lies in ensuring compatibility with your equipment and predicting cable performance in different environments. Let’s break down some key areas often found in the datasheet:
- Conductor Gauge: Indicates the thickness of the wire (e.g., 22 AWG, 24 AWG). Lower AWG numbers mean thicker wires, offering lower resistance.
- Capacitance: A critical parameter for audio cables, especially long runs. Lower capacitance generally results in better high-frequency response.
- Shielding: Describes the type of shield (e.g., braid, foil) and its coverage percentage. Higher coverage provides better protection against electromagnetic interference (EMI).
The datasheet also details the cable’s electrical properties, such as impedance, capacitance, and inductance, which are vital for maintaining signal integrity. These parameters impact how the audio signal travels through the cable, influencing frequency response and signal clarity. Impedance matching, for instance, is critical in many audio systems, and the datasheet will provide the cable’s impedance value. Furthermore, you will find ratings for voltage and temperature that dictate the safe operational limits. Exceeding these limits can damage the cable and potentially pose safety hazards. It’s also useful to see temperature rating in this format:
- Minimum Temperature: -20°C
- Maximum Temperature: +75°C
Beyond electrical specifications, the Belden 9773 Datasheet provides physical characteristics. These include the overall cable diameter, jacket material (typically PVC for durability), and bend radius. The bend radius indicates how tightly the cable can be bent without damaging its internal conductors or shielding. Knowing the overall diameter is crucial for selecting appropriate connectors and cable management solutions. Having these measurements in advance will help plan a project. Below is an example.
| Property | Value |
|---|---|
| Overall Diameter | 0.15 inches |
