CSPEMI202AG

Overview

The CSPEMI202AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) designed to reduce EMI/RFI emissions while providing ESD protection. It features an integrated ESD suppressor diode array with bidirectional capability and a 5V rating. The component is housed in a compact 5-pin WLCSP package, suitable for space-constrained applications.

Feature Summary

• Integrates dual pi-style RC filters for effective EMI suppression
• Provides bidirectional ESD protection for sensitive signal lines
• Monolithic IC design minimizes footprint and simplifies assembly

Applications

• Headset microphone interfaces
• Audio interfaces of wireless devices
• Portable electronic equipment requiring EMI filtering

Procurement Notes

Verify the specific ordering suffix 'G' confirms the tape and reel packaging format as indicated in official documentation. Ensure compatibility with standard surface mount reflow processes. Confirm that the 5-pin WLCSP package dimensions meet the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when simultaneous EMI filtering and ESD protection are required for audio or data lines in compact designs. The integrated dual filter structure reduces the need for discrete components. Consider the 5V ESD rating and bidirectional nature for protecting low-voltage signal interfaces against electrostatic discharge events.

Part Context

This part belongs to onsemi's portfolio of passive and mixed-signal components focused on signal integrity and protection.
