EXC-CET103U

Overview

The EXC-CET103U is a surface-mount LC (T-Type) EMI filter designed for effective noise suppression on power lines and high-speed signal lines. It features a third-order low-pass configuration with one channel, rated capacitance of 10000pF (0.01µF), and a maximum current rating of 2A. The component operates within a temperature range of -40°C to 85°C and has a rated voltage of 50V. Packaged in an 1807 (4518 Metric) footprint with three PC pads, it targets data line applications in mobile devices.

Feature Summary

• Provides effective noise suppression for power lines and high-speed signal lines
• Utilizes a third-order LC T-type low-pass filter architecture
• Supports high current handling up to 2A maximum

Applications

• Data lines for mobile devices
• Power line noise suppression
• High-speed signal line filtering

Procurement Notes

Verify the exact package dimensions against the 1807 (4518 Metric) specification before integration. Confirm that the 2A current rating and 50V voltage rating meet the circuit requirements. Check the operating temperature range of -40°C to 85°C for environmental suitability. Ensure compatibility with surface mount assembly processes. Note that availability may vary as some distributors list this part as obsolete.

Selection Notes

Select this component when a third-order low-pass response is required for EMI reduction in compact designs. The 10000pF capacitance value suits specific noise frequency ranges associated with the EXCCET series. Consider the 2A current capacity for power integrity in mobile device data lines. The SMD form factor facilitates automated assembly in space-constrained PCB layouts.

Part Context

This component belongs to the Panasonic EXCCET series of chip EMI filters. The series offers multiple capacitance values tailored to different noise frequencies. The EXC-CET103U specifically provides a 10000pF rating within this family, designed for surface-mount applications requiring robust noise suppression in electronic equipment.

Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers within the EXCCET series or equivalent LC filter families. Ensure any replacement matches the 1807 footprint, 2A current rating, and 10000pF capacitance. Verify that alternative components maintain the same third-order low-pass characteristics and temperature ratings.
