AEMIF-0805-301M-16-T

Overview

The AEMIF-0805-301M-16-T is a surface-mount RC Pi EMI filter from Abracon LLC, housed in an 0805 (2012 Metric) package. It features a resistance of 1 Ohm and a cutoff frequency of 300 MHz. The component supports a maximum current rating of 300 mA and operates within a voltage range up to 16 V. It provides attenuation of 20 dB at frequencies between 550 MHz and 2 GHz. The device functions as an unshielded filter with standard SMD/SMT termination, designed for efficient noise suppression in compact electronic layouts.

Feature Summary

• Integrates RC Pi topology for effective electromagnetic interference suppression
• Provides significant signal attenuation across high-frequency ranges
• Utilizes compact surface-mount construction for space-constrained designs

Applications

• High-speed data line filtering
• Power supply noise reduction
• Signal integrity enhancement in communication modules

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm that the 300 mA current rating aligns with the target circuit's continuous load requirements. Ensure the 16 V rated voltage exceeds the maximum operating potential of the application to prevent component failure. Cross-reference the 0805 footprint dimensions with the printed circuit board layout to guarantee mechanical compatibility.

Selection Notes

Select this component when a low-profile solution is required for broadband noise suppression. The 1 Ohm resistance offers minimal impact on DC signals while effectively attenuating RF interference. Consider the 300 mA current capacity for moderate power applications. The 300 MHz cutoff frequency makes it suitable for filtering above-standard bandwidth signals without affecting lower frequency operations.

Part Context

This part belongs to Abracon's AEMIF series of integrated EMI filters. These components combine resistive and capacitive elements into a single surface-mount package. The series is engineered to replace discrete LC networks, reducing board space and assembly complexity. The 0805 form factor ensures compatibility with standard automated pick-and-place manufacturing processes.
