EXC-14CS900H

Common Mode Chokes Overview

The EXC-14CS900H is a surface-mount common mode filter with integrated ESD protection, manufactured by Panasonic. It features a 90 ohm impedance at 100 MHz and supports a maximum DC current of 100 mA. The component has a typical DC resistance of 3.3 ohms and operates within a temperature range of -40°C to +85°C. Designed for compact PCB mounting, it utilizes a 2-line configuration in an SMD package.

Common Mode Chokes Feature Summary

• Integrated TVS diode structure for electrostatic discharge suppression
• Dual-line common mode noise filtering capability
• Compact surface-mount design for space-constrained applications

Common Mode Chokes Applications

• ESD protection for high-speed data lines
• Common mode noise suppression in portable electronics

Common Mode Chokes Procurement Notes

Verify the exact part number suffix as sources indicate both EXC-14CS900U and EXC-14CS900H variants exist. Confirm availability status as some listings mark the component as discontinued or limited. Ensure the selected variant matches the required impedance and current specifications for the target circuit design before procurement.

Common Mode Chokes Selection Notes

Select this component when simultaneous ESD protection and common mode noise filtering are required in a single footprint. The 100 mA current rating suits low-power signal lines. Verify that the 90 ohm impedance aligns with the operating frequency requirements of the specific interface being protected.

Common Mode Chokes Part Context

This component belongs to the EXC14CS series of common mode filters from Panasonic Industry. These devices combine passive filtering elements with active ESD protection structures. The series is designed for modern electronic systems requiring robust signal line protection against transient events while maintaining signal integrity.
