E-TA2012 T 4DB N3

Attenuators Overview

The E-TA2012 T 4DB N3 is an RF attenuator manufactured by Nidec Components Corporation. It provides a fixed attenuation value of 4dB with a nominal impedance of 50 Ohms. The component operates within a frequency range of 0 Hz to 3 GHz and has a power rating of 63mW. It is housed in a surface-mount 0805 (2012 Metric) package, designed for integration into high-frequency circuit applications requiring precise signal reduction.

Attenuators Feature Summary

• Fixed 4dB attenuation value for consistent signal level control
• 50 Ohm nominal impedance matching standard RF systems
• Operational frequency range extending up to 3 GHz
• Surface-mount 0805 package format for automated assembly

Attenuators Applications

• RF signal path conditioning in communication modules
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment
• Attenuation stages in wireless transceiver designs

Attenuators Procurement Notes

Verify the complete part number including suffixes such as N3 against official manufacturer documentation to ensure correct packaging and tolerance specifications. Confirm that the 0805 footprint aligns with PCB design requirements. Cross-reference datasheet parameters like power rating and frequency response with system constraints before finalizing procurement orders.

Attenuators Selection Notes

Select this component when a fixed 4dB attenuation is required in a 50 Ohm system operating below 3 GHz. Ensure the 63mW power handling capability meets the maximum expected signal power in the application. The 0805 package size must be compatible with available board space and manufacturing capabilities for surface-mount technology.

Attenuators Part Context

This part belongs to the E-TA series of RF attenuators from Nidec Components Corporation. The series offers various attenuation values and impedance options in compact surface-mount packages. The E-TA2012 designation indicates the specific package size and form factor within the broader product line dedicated to RF signal management.

Attenuators Replacement Considerations

Check for direct substitutes within the same series offering identical 4dB attenuation and 50 Ohm impedance. Verify that alternative components match the 0805 package dimensions and 63mW power rating. Ensure frequency performance up to 3 GHz is maintained by comparable parts if substitution is necessary.
