AVRF041A150MT242

Overview

The TDK AVRF041A150MT242 is an EMI notch filter circuit designed for high-frequency noise suppression. It features a capacitance of 15 pF with a tolerance of ±20% and operates at a maximum voltage of 10 VDC. The component provides electrostatic discharge (ESD) protection rated at 8 kV. It utilizes a surface-mount device (SMD) package in the 01005 (0402 metric) footprint, measuring 0.4 mm in length, 0.2 mm in width, and 0.2 mm in height. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates ESD protection and noise suppression functions within a single compact component.
• Provides targeted noise attenuation specifically in the 2.4 GHz frequency band.
• Utilizes a miniature 01005 surface-mount package to conserve printed circuit board space.

Applications

• Noise filtering for wireless communication modules operating in the 2.4 GHz ISM band
• Protection of sensitive input/output lines against electrostatic discharge events
• Signal integrity enhancement in compact mobile electronic devices

Procurement Notes

Verify the specific datasheet version corresponding to the manufacturing date code, as TDK may update electrical characteristics or mechanical dimensions over time. Confirm that the 01005 package size aligns with your PCB land pattern design rules. Ensure that the 10 VDC rating is sufficient for your specific circuit application. Check for RoHS compliance status if required by your regional regulations.

Selection Notes

Select this component when both ESD protection and RF noise filtering are required in a single location on the board. The 15 pF capacitance value is suitable for high-speed digital or RF lines where minimal signal loading is necessary. The 01005 package is appropriate for high-density layouts where standard 0402 components do not fit. Consider the 8 kV ESD rating relative to the expected environmental exposure levels.
