Overview
The CM1423-03CP is a Secure Digital (SD) Card EMI filter array with integrated ESD protection, manufactured by California Micro Devices. It features six RC Pi-filter functions designed for data line filtering in mobile devices. The component utilizes a 20-WFBGA WLCSP package. Key electrical parameters include a channel resistance of 100 Ohms and a capacitance of 12 pF per filter stage. It provides attenuation of 25 dB at 1 GHz.
Feature Summary
- Integrates six RC Pi-filter stages for effective EMI suppression on data lines
- Provides electrostatic discharge (ESD) protection alongside signal filtering
- Optimized specifically for Secure Digital (SD) card interface applications
Applications
- Data lines for mobile devices
- Secure Digital (SD) card interfaces
- EMI filtering in portable electronics
Procurement Notes
Verify the specific suffix '03CP' to confirm the 20-WFBGA WLCSP package type and 100 Ohm resistance value. Ensure compatibility with SD card controller designs requiring 6-channel filtering. Cross-reference the manufacturer's latest datasheet for pinout definitions and thermal specifications before finalizing procurement orders.
Selection Notes
Select this component when designing SD card slots requiring combined EMI filtering and ESD protection in a compact footprint. The 100 Ohm series resistance and 12 pF shunt capacitance are suitable for high-speed data lines. Consider the WLCSP package size constraints and soldering requirements during PCB layout planning.
Part Context
This part belongs to the CM1423 series from California Micro Devices, which focuses on EMI filter arrays with ESD protection. The series includes variants like CM1423-01CS and CM1423-03CS, differing primarily in packaging and specific parameter configurations while maintaining similar functional architectures for data line protection.
Replacement Considerations
Check for direct substitutes within the CM1423 family, such as CM1423-03CS, noting potential package differences. Verify that any alternative maintains the 6-function Pi-filter configuration and compatible 100 Ohm resistance values to ensure circuit performance consistency.
