NMF3010FCT1G

Overview

The NMF3010FCT1G is a dual-stage, differential line filter with ESD protection designed for portable device audio inputs. It serves as the second stage in a filtering scheme, providing additional signal filtering at a distance from the primary interface. The component features separate power and analog grounds to enhance ESD protection and filtering circuitry performance. It supports two channels or differential transmission lines.

Feature Summary

• Provides low-pass filtering for incoming audio signals
• Includes IEC 61000-4-2 Grade ±15 kV contact ESD protection on inputs and VCC pins
• Features separate power (PGND) and analog (AGND) ground connections

Applications

• Portable electronic devices requiring audio input protection
• Second-stage filtering in differential audio transmission lines
• Signal conditioning for microphone inputs

Procurement Notes

Verify that the specific ordering suffix matches the required package type and shipping quantity. Confirm that the application environment falls within the specified operating temperature range of -40°C to 85°C. Ensure that the system design accounts for the separate power and analog ground requirements to maintain intended ESD protection levels.

Selection Notes

Select this component when a secondary filtering stage is needed downstream from a primary ESD protection device like the NMF3000. It is suitable for applications requiring robust differential signal integrity and high-level ESD immunity on audio lines without active biasing requirements.

Part Context

This part belongs to the NMF3000/NMF3010 family of dual-stage filters. While the NMF3000 acts as the first stage near the external interface, the NMF3010 functions as the second stage placed further into the system. Both are Pb-Free devices utilizing flip-chip packaging.
