Overview
The CM1402-03CP is an EMI filter array with integrated ESD protection, designed for SIM card applications. It integrates three pi filters (C-R-C) and two additional channels of ESD protection in a 10-WFBGA package. The component features RC values of 20pF-47Ω-20pF and 20pF-100Ω-20pF. It includes avalanche-type ESD diodes on every pin to provide high-level protection. The cutoff frequency is specified at 77 MHz.
Feature Summary
- Integrates three pi filters (C-R-C) for EMI suppression
- Includes two additional channels of ESD protection
- Features avalanche-type ESD diodes on every pin
- Designed specifically for SIM card signal lines
Applications
- SIM card EMI filtering
- Mobile device signal line protection
- Portable electronic equipment ESD protection
Procurement Notes
Verify the exact part number suffix, as variations like CM1402-03CP indicate specific internal configurations or packaging. Confirm the package type is 10-WFBGA and check for RoHS compliance status. Ensure the supplier provides official datasheets matching the onsemi documentation to avoid counterfeit components. Cross-reference the manufacturer part number with authorized distributor lists for authenticity.
Selection Notes
Select this component when simultaneous EMI filtering and ESD protection are required for SIM interfaces. The integrated pi filter structure reduces board space compared to discrete solutions. Consider the 77 MHz cutoff frequency for compatibility with target signal speeds. The 10-WFBGA package suits compact mobile designs requiring surface-mount assembly.
Part Context
This component belongs to onsemi's EMI filter circuit family, categorized under filters. It is distinct from image sensors or other semiconductor products offered by the manufacturer. The product serves as a passive protection network rather than an active processing unit.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints if considering alternative manufacturers.
