CSPEMI202FCTAG

Overview

The CSPEMI202FCTAG is a second-order low-pass RC (Pi) EMI filter designed for audio applications. It integrates two channels with fixed internal components: resistors of 68 Ohms and capacitors of 47 pF per channel. The device is housed in a compact 5-XFBGA, WLCSP package. It operates within a temperature range of -40°C to 85°C. This component provides EMI filtering and ESD protection for headset microphone lines.

Feature Summary

• Integrates dual-channel RC filtering topology
• Provides electromagnetic interference suppression
• Includes electrostatic discharge protection capabilities

Applications

• Headset microphone line filtering
• Audio signal path EMI reduction
• Portable device audio interface protection

Procurement Notes

Verify the current product status as sources indicate this part may be obsolete. Confirm availability through authorized distributors or secondary market suppliers if standard supply chains do not list it. Ensure the specific package type matches design requirements before ordering.

Selection Notes

Select this component for designs requiring integrated EMI filtering and ESD protection in a minimal footprint. The fixed 68 Ohm resistor and 47 pF capacitor values define the cutoff frequency characteristics suitable for audio bandwidths. Verify compatibility with the target PCB layout for the 5-XFBGA package.

Part Context

This component belongs to onsemi's analog and mixed signal category, specifically within the EMI/RFI filters segment. It serves as a passive network solution for noise suppression in consumer electronics, particularly targeting mobile and portable audio devices where space constraints are critical.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the potentially obsolete status, alternative sourcing strategies or redesigning with currently active components from the manufacturer's portfolio may be necessary.
