Attenuators Procurement Notes

Verify the specific suffix 'N4' against official manufacturer documentation to confirm exact tolerance and termination specifications. Ensure the component matches the required 0805 footprint and 63 mW power rating for the target application. Cross-reference the full part number with authorized distributors to avoid obsolete or incompatible variants.

Attenuators Selection Notes

Select this component when a fixed 2 dB attenuation is required at 50 Ohms within a 3 GHz bandwidth. The 0805 package size suits space-constrained PCB layouts. Confirm that the 63 mW power handling capability aligns with the maximum expected signal levels in the circuit design to ensure reliable operation.

Attenuators Part Context

This model belongs to the E-TA series of thin-film RF attenuators from Nidec Components. These components are engineered for consistent performance across microwave frequencies. The series offers various attenuation values and packages, with the E-TA2012 specifically targeting SMT assembly processes for consumer and industrial electronics.

Attenuators Replacement Considerations

Direct substitutes include other 2 dB, 50 Ohm, 0805 RF attenuators from compatible manufacturers. Verify electrical parameters such as insertion loss and VSWR match the original specifications. Check physical dimensions and pinout compatibility before substitution.
