E-TA2012 7DB N3

Attenuators Overview

The Nidec Components Corporation E-TA2012 7DB N3 is a surface-mount RF attenuator designed for high-frequency circuit applications. It provides a fixed attenuation value of 7 dB within a frequency range of 0 Hz to 3 GHz. The component operates at a maximum power rating of 63 mW and features a nominal impedance of 50 Ohms. It is housed in an 0805 (2012 Metric) package, suitable for automated assembly processes.

Attenuators Feature Summary

• Provides precise signal reduction with a fixed 7 dB attenuation value
• Operates effectively across a wide frequency spectrum from DC to 3 GHz
• Designed for low-power applications with a 63 mW power handling capability
• Utilizes a compact 0805 surface-mount package for space-efficient integration

Attenuators Applications

• Signal leveling in RF and IF circuits
• Impedance matching networks in communication systems
• Test and measurement equipment requiring controlled signal attenuation

Attenuators Procurement Notes

Verify the specific suffix 'N3' against official manufacturer documentation to confirm compliance with RoHS3 standards and moisture sensitivity level classifications. Ensure that the ordering information matches the exact part number to avoid discrepancies in attenuation values or package dimensions. Cross-reference datasheets for any updates regarding environmental compliance or packaging specifications before finalizing procurement orders.

Attenuators Selection Notes

Select this component when a fixed 7 dB attenuation is required in 50 Ohm systems operating up to 3 GHz. Consider the 63 mW power limit for low-signal applications. The 0805 footprint dictates board layout constraints. Verify thermal management requirements relative to the low power dissipation. Confirm availability of the specific tape and reel packaging if automated placement is utilized.

Attenuators Part Context

This part belongs to the E-TA2012 series of thin-film chip resistors configured as RF attenuators. The series offers various attenuation values including 2 dB, 4 dB, and 7 dB options. These components are engineered for stability and precision in microwave and radio frequency applications, providing reliable performance in compact electronic designs.

Attenuators Replacement Considerations

Compatible substitutes include the E-TA2012 7DB N7 variant, which shares identical electrical characteristics but differs in packaging format. Other series members such as E-TA2012 2DB N3 or E-TA2012 4DB N3 offer different attenuation levels within the same package and frequency range.
