Import Attenuator — Buy in Bulk from Supplier in China

The attenuator from Shanghai Yingda Electronics is a precision component designed to manage signal levels in electronic systems without introducing distortion. Built for telecommunications and broadcast applications, it delivers consistent attenuation across a broad frequency range, ensuring signal integrity in high-demand environments. The unit features a compact, space-saving design that integrates seamlessly into existing setups, while its industrial-grade materials provide durability under environmental stress.

Available in customizable configurations to match specific attenuation requirements, this device is constructed using standard RF materials such as brass or stainless steel for the housing, with typical connectors including SMA, BNC, or N-type. The internal resistive elements are often composed of thin-film or wirewound resistors, providing typical attenuation ranges from 1 dB to 70 dB with a standard VSWR of 1.2:1 or better. These components adhere to industry standards like MIL-STD-348 for environmental testing and IEC 60068 for mechanical robustness.

Telecommunications providers, broadcast engineers, and industrial automation firms rely on attenuators like this to fine-tune signal strength in transmitters, receivers, and test equipment. Buyers should confirm compatibility with their system’s frequency range and impedance (commonly 50 Ω or 75 Ω). The supplier offers flexible trade terms, including FOB and CIF shipping options, with packaging typically designed to protect against electrostatic discharge and physical damage during transit.

Shanghai Yingda Electronics operates from No. 889 Wu Zhong Rd. in Shanghai’s Minhang District, a hub for electronics manufacturing in China. The company is registered as an imported-tier supplier, indicating it sources or distributes components for international markets. Its harbor trust tier suggests a baseline level of verification, though the response rate and average response time are currently unrecorded, which buyers may want to confirm before initiating inquiries.

The supplier’s focus is on electronic components, including signal management devices like attenuators. While the profile does not specify certifications, years in business, or client lists, its address and tier classification provide a starting point for due diligence. Buyers should request documentation such as ISO or CE certificates directly from the supplier to validate quality standards. The company’s product descriptions emphasize performance and reliability, but specific technical data sheets should be reviewed for precise specifications.
