CM1450-08CP

Overview

The CM1450-08CP is an 8-channel LC (Pi) EMI filter array with integrated ESD protection, manufactured by onsemi. It features a 20-WFBGA WLCSP package measuring 4.01mm x 1.38mm x 0.70mm. Key electrical parameters include a total inductance of 17nH and total capacitance of 14pF. The device operates within a temperature range of -40°C to +85°C and supports data rates up to 160Mbps. It provides a roll-off frequency at -10dB attenuation of 400MHz.

Feature Summary

• Integrates ESD protection with LC Pi-filter topology for signal integrity
• Compact WLCSP footprint suitable for space-constrained mobile designs
• Supports high-speed data transmission lines

Applications

• Mobile device data lines
• LCD interface circuits
• Camera module interfaces

Procurement Notes

Verify component status as the part may be discontinued or subject to limited supply. Confirm current availability through authorized distributors. Ensure the specific ordering suffix matches the required packaging format. Validate that the 20-WFBGA pinout aligns with the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component for applications requiring multi-channel EMI suppression and ESD protection in a minimal footprint. The 17nH inductance and 14pF capacitance values are optimized for high-speed data lines. Consider the 400MHz roll-off frequency when evaluating signal bandwidth requirements against noise attenuation needs.

Part Context

This component belongs to the CM1450 series of EMI filter arrays designed for portable electronics. It addresses the need for compact filtering solutions in modern mobile devices where board space is limited. The series integrates passive filtering elements with electrostatic discharge protection structures.

Replacement Considerations

The CM1451-08CP is a related variant with different inductance and capacitance values (34nH/28.5pF). Verify if the higher attenuation characteristics of the CM1451 are required or if the original specifications suffice.
