E-TA2012 T 3DB N7

Attenuators Overview

The E-TA2012 T 3DB N7 is a surface-mount RF attenuator manufactured by Nidec Components. It provides a fixed attenuation of 3dB within a frequency range of 0 Hz to 3 GHz. The component operates at a 50 Ohm impedance and is housed in an 0805 (2012 Metric) package.

Attenuators Feature Summary

• Fixed 3dB attenuation value for signal level control
• Broadband operation covering DC to 3 GHz frequencies
• Standard 50 Ohm impedance matching for RF systems
• Compact 0805 surface-mount package design

Attenuators Applications

• RF signal path attenuation
• Impedance matching networks
• Test and measurement equipment
• Wireless communication modules

Attenuators Procurement Notes

Verify the specific suffix 'N7' against official manufacturer documentation to confirm material composition and plating specifications, as these variants may differ from standard versions. Ensure the selected part number matches the required 3dB attenuation and 0805 footprint for your circuit design.

Attenuators Selection Notes

Select this component when a precise 3dB reduction is needed in low-power RF applications up to 3 GHz. Consider the 63mW power rating limit typical for this series and ensure thermal management aligns with system requirements. Verify compatibility with standard reflow soldering profiles for the 0805 package.

Attenuators Part Context

This part belongs to the E-TA2012 series of thin-film chip resistors designed for RF attenuation. These components are engineered for high stability and precision in microwave and radio frequency circuits, offering reliable performance in compact form factors suitable for modern electronic devices.

Attenuators Replacement Considerations

Compatible substitutes include other 3dB, 50 Ohm, 0805 RF attenuators from manufacturers such as Mini-Circuits or Pasternack, provided they meet the same electrical specifications and package dimensions.
