E-TA2012 2DB N4

Attenuators Overview

The E-TA2012 2DB N4 is a surface-mount RF attenuator manufactured by Nidec Components Corporation. It provides a fixed attenuation of 2 dB with a nominal impedance of 50 Ohms. The component utilizes an 0805 (2012 Metric) package format, suitable for automated assembly processes. It is rated for a power handling capacity of 63 mW and complies with RoHS standards. This device is designed for integration into radio frequency and intermediate frequency circuits requiring precise signal level reduction.

Attenuators Feature Summary

• Provides fixed 2 dB attenuation for signal conditioning
• Maintains 50 Ohm nominal impedance for system matching
• Utilizes compact 0805 surface mount package geometry

Attenuators Applications

• RF circuit signal level adjustment
• IF stage gain control
• Test and measurement equipment calibration

Attenuators Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact attenuation value and tolerance specifications. Ensure the selected variant matches the required impedance and power rating for the target application environment. Confirm compliance status with current regulatory requirements prior to procurement.

Attenuators Selection Notes

Select this component based on the requirement for a fixed 2 dB attenuation value within a 50 Ohm system. Consider the 0805 package size for board space constraints and the 63 mW power rating for thermal management. Evaluate the surface mount technology compatibility with existing assembly lines.

Attenuators Part Context

This part belongs to the E-TA series of thin film chip attenuators from Nidec Components Corporation. These components are engineered for high reliability in demanding electronic environments. The series offers various attenuation values and package options to support diverse RF design architectures.

Attenuators Replacement Considerations

SM-42TA203 is listed as a direct substitute in distributor records, though it is a trimmer potentiometer rather than an RF attenuator. Verify functional equivalence carefully before substitution.
