ATC2525CT-2000JN-94TR

Attenuators Overview

The ATC2525CT-2000JN-94TR is a surface-mount RF attenuator manufactured by Vishay Barry. It provides a fixed attenuation of 20 dB with a tolerance of ±5%. The device operates across a frequency range from DC to 2 GHz and features a nominal impedance of 50 Ohms. It is rated for a maximum input power of 15 Watts. The component utilizes an aluminum oxide (Al2O3) substrate and employs a wraparound slot-wound construction. It is housed in a compact 4-SMD, no-lead package designed for automated surface mount assembly.

Attenuators Feature Summary

• Utilizes aluminum oxide substrate for thermal stability
• Features wraparound slot-wound construction for precision
• Supports surface mount installation techniques

Attenuators Applications

• RF signal conditioning in communication systems
• Test and measurement equipment calibration
• Microwave circuit power level adjustment

Attenuators Procurement Notes

Verify the specific suffix '94' against the manufacturer's current documentation to confirm packaging configuration and tape-and-reel specifications. Ensure that the 15W power rating aligns with the thermal management capabilities of the target application environment. Confirm RoHS compliance status as indicated in the latest datasheet revision prior to final procurement authorization.

Attenuators Selection Notes

Select this component when a precise 20 dB attenuation value is required within the DC to 2 GHz bandwidth. The 15W power handling capability makes it suitable for high-power RF paths where standard thin-film resistors may fail. The SMD form factor is ideal for space-constrained PCB layouts requiring robust thermal dissipation through the ceramic substrate.

Attenuators Part Context

This part belongs to the ATC2525CT series of chip attenuators from Vishay Barry. The series offers various attenuation values ranging from 0 to 30 dB and power ratings up to 30W. These components are characterized by their stable performance over temperature and frequency, utilizing advanced ceramic materials and precision winding techniques to ensure reliability in demanding RF environments.

Attenuators Replacement Considerations

Direct substitutes include other Vishay ATC2525CT variants with matching 20 dB attenuation and 15W power ratings. Cross-brand replacements must match the 50 Ohm impedance, 2 GHz frequency limit, and 4-SMD footprint. Verify that alternative components support the same 15W continuous power dissipation without derating.
