ATC2010CT-0100JN-93TR

Attenuators Overview

The ATC2010CT-0100JN-93TR is a surface-mount RF attenuator manufactured by Vishay Barry. It features a fixed attenuation value of 1dB and operates within a frequency range of 0 Hz to 3 GHz. The component is rated for 5W of power handling and maintains a nominal impedance of 50 Ohms. It utilizes an alumina (Al2O3) substrate for thermal stability and is housed in a compact 2010 (5025 Metric) package with four SMD leads.

Attenuators Feature Summary

• Fixed 1dB attenuation for precise signal level control
• High power handling capability of 5W
• Wideband operation from DC to 3 GHz
• Robust alumina substrate construction

Attenuators Applications

• RF signal conditioning in communication systems
• Test and measurement equipment calibration
• Microwave circuit impedance matching networks

Attenuators Procurement Notes

Verify the specific suffix JN-93TR against the manufacturer's datasheet to confirm tolerance and tape-and-reel specifications. Ensure compatibility with standard reflow soldering profiles for 2010 packages. Cross-reference the Vishay part number with authorized distributors to avoid counterfeit components, as generic listings may lack critical electrical verification data.

Attenuators Selection Notes

Select this component when a low-loss, fixed 1dB reduction is required in high-frequency circuits up to 3 GHz. The 5W power rating suits moderate-power applications, while the 2010 footprint offers space efficiency. Consider thermal management requirements due to the Al2O3 substrate, ensuring adequate PCB copper area for heat dissipation during continuous operation.

Attenuators Part Context

This part belongs to the ATC2010 series of chip attenuators, designed for surface-mount technology. It complements other values in the family, such as 3dB or 6dB variants, providing standardized attenuation steps. The series is engineered for reliability in harsh environments, leveraging Vishay's expertise in thin-film and thick-film resistor technologies for consistent performance.

Attenuators Replacement Considerations

Direct substitutes include other Vishay ATC2010 series parts with identical 1dB attenuation and 5W ratings, such as ATC2010CT-0100JN-94TR if packaging differences are acceptable. Verify that alternative manufacturers offer equivalent 50 Ohm impedance and 3 GHz bandwidth to maintain circuit integrity without redesign.
