E-TA2012 10DB N4

Attenuators Overview

The E-TA2012 10DB N4 is a surface-mount RF attenuator manufactured by Nidec Components Corporation. It provides a fixed attenuation value of 10 dB 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 63 mW. It utilizes an 0805 (2012 Metric) package format for compact integration.

Attenuators Feature Summary

• Fixed 10 dB attenuation value
• 50 Ohm nominal impedance
• Wideband operation up to 3 GHz
• Compact 0805 surface-mount package

Attenuators Applications

• RF signal level adjustment in communication systems
• Impedance matching networks
• Test and measurement equipment
• Wireless module input protection

Attenuators Procurement Notes

Verify the exact part number against manufacturer documentation to ensure correct attenuation and impedance specifications. Confirm RoHS compliance status and lead times through authorized distributors. Check for alternative suffixes that may indicate different tolerance or packaging options.

Attenuators Selection Notes

Select this component when a precise 10 dB reduction is required in 50-ohm RF circuits. Ensure the operating frequency does not exceed 3 GHz and power levels remain below 63 mW. Consider thermal management requirements due to low power dissipation limits in the small SMD package.

Attenuators Part Context

This device belongs to the E-TA2012 series of thin-film RF attenuators from Nidec Components. The series offers various attenuation values in a standardized 0805 footprint, allowing designers to maintain consistent board layouts while adjusting signal strength across different frequency bands.

Attenuators Replacement Considerations

Public confirmed substitutes include other 10dB 50Ohm 0805 RF attenuators from manufacturers such as Mini-Circuits or Qorvo, provided they meet the 3GHz frequency and 63mW power constraints.
