E-TA2012 T 4DB N7

Attenuators Overview

The E-TA2012 T 4DB N7 is a surface-mount RF attenuator manufactured by Nidec Components Corporation. It provides a fixed attenuation value of 4 dB with a nominal impedance of 50 Ohms. The component utilizes an 0805 (2012 Metric) package format, suitable for automated assembly processes. It operates within a frequency range of 0 Hz to 3 GHz and has a power rating of 63 mW.

Attenuators Feature Summary

• Fixed 4 dB attenuation value for signal level control
• 50 Ohm nominal impedance matching standard RF systems
• Surface-mount construction in 0805 package for PCB integration

Attenuators Applications

• RF signal path attenuation in communication modules
• Impedance matching networks in wireless devices
• Signal conditioning in test and measurement equipment

Attenuators Procurement Notes

Verify the specific suffix 'N7' against official Nidec Copal Electronics documentation to confirm manufacturing origin and material specifications. Ensure the selected variant matches the required 4 dB tolerance and 63 mW power handling capabilities for the target application environment.

Attenuators Selection Notes

Select this component when a precise 4 dB reduction is required in a 50 Ohm system operating up to 3 GHz. The 0805 footprint offers space efficiency compared to larger packages. Confirm that the 63 mW power rating aligns with the maximum expected signal power in the circuit design.

Attenuators Part Context

This part belongs to the E-TA2012 series of thin-film chip resistors designed as RF attenuators. The series includes various attenuation values and package sizes, providing standardized solutions for RF engineers requiring reliable signal attenuation in compact electronic designs.

Attenuators Replacement Considerations

Compatible substitutes include other 0805 4dB 50 Ohm RF attenuators from manufacturers such as Johanson Technology or Murata, provided they meet the 3 GHz frequency and 63 mW power requirements.
