ATC2525CT-0300JN-94TR

Attenuators Overview

The ATC2525CT-0300JN-94TR is a fixed RF attenuator manufactured by Vishay Barry. It operates within a frequency range of 0 Hz to 2 GHz and provides a nominal attenuation value of 3 dB with a tolerance of ±0.5 dB (ranging from 2.9 dB to 3.5 dB). The component features a 50 Ohm impedance and supports a power rating of 15 W. It utilizes an aluminum oxide (Al2O3) substrate in a 4-SMD, no-lead package design.

Attenuators Feature Summary

• Utilizes aluminum oxide substrate for thermal stability
• Supports surface mount integration via SMD package
• Operates across DC to 2 GHz frequency spectrum

Attenuators Applications

• RF signal path attenuation
• Test and measurement equipment
• Wireless communication systems

Attenuators Procurement Notes

Verify the specific suffix '94' against the manufacturer's official documentation to confirm packaging and tape specifications. Ensure the order matches the exact Vishay part number to avoid confusion with similar series variants. Cross-reference the datasheet for handling instructions related to the ceramic substrate.

Attenuators Selection Notes

Select this component when a precise 3 dB attenuation is required at 50 Ohms up to 2 GHz. The 15 W power rating allows for high-power applications compared to standard thin-film alternatives. Consider the 4-SMD footprint for PCB layout compatibility and verify thermal management requirements for continuous operation.

Attenuators Part Context

This device belongs to the ATC2525 series of chip attenuators from Vishay Barry. These components are designed for robust performance in demanding RF environments. The series offers various attenuation values while maintaining consistent impedance and power handling capabilities across the family.

Attenuators Replacement Considerations

Direct substitutes include other Vishay ATC2525 series parts with matching 3 dB attenuation and 15 W ratings. Verify that alternative packages maintain the 4-SMD form factor for direct board replacement without layout modifications.
