EXC-24CS900U

Common Mode Chokes Overview

The EXC-24CS900U is a surface-mount common mode choke with integrated ESD protection, designed for signal line filtering. It features a 0503 (1.25mm x 1.00mm) package and operates within a temperature range of -40°C to 85°C. The component provides an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 100 mA. Its DC resistance is 3 Ohms per line, and it is rated for 5V DC. This device integrates TVS diodes for electrostatic discharge suppression.

Common Mode Chokes Feature Summary

• Integrates common mode chokes with built-in ESD protection diodes
• Compact 0503 surface mount footprint for space-constrained designs
• Designed for high-frequency noise suppression on signal lines

Common Mode Chokes Applications

• Portable electronic devices requiring ESD protection

• Data interface circuits sensitive to electromagnetic interference

Common Mode Chokes Procurement Notes

Verify component status as the EXC-24CS900U is listed as obsolete by Panasonic Industry. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with RoHS3 standards and check for alternative sourcing options due to discontinuation. Validate datasheet revisions before integration into new designs.

Common Mode Chokes Selection Notes

Select this component for applications requiring combined common mode noise filtering and ESD protection in a minimal footprint. Consider the 100 mA current rating and 90 Ohm impedance at 100 MHz for signal integrity requirements. Evaluate the 0503 package dimensions against PCB layout constraints. Verify thermal performance within the specified -40°C to 85°C operating range.

Common Mode Chokes Part Context

Part of the EXC24CS series from Panasonic Industry, focusing on EMC/ESD components. This series targets signal line protection in portable and compact electronic systems. The EXC-24CS900U specifically combines inductive filtering with semiconductor-based ESD suppression in a single surface-mount package.

Common Mode Chokes Replacement Considerations

As the part is obsolete, identify equivalent components from the EXC24 series or other manufacturers offering similar 0503 package common mode chokes with integrated ESD protection. Verify matching electrical parameters including impedance, current rating, and package dimensions.
