EXC-CET102U

Overview

The EXC-CET102U is a surface-mount EMI filter manufactured by Panasonic Electronic Components. It utilizes an LC T-type topology configured as a third-order low-pass filter with a single channel. The component features a capacitance value of 1000pF and supports a current rating of 2A. Designed for compact applications, it is housed in an 1807 (4518 Metric) package footprint. The unit operates with a voltage rating of 50V and provides attenuation characteristics up to 110MHz.

Feature Summary

• LC T-type architecture providing third-order low-pass filtering performance
• Compact 1807 surface-mount package design suitable for space-constrained layouts
• Single-channel configuration optimized for differential or common-mode noise suppression

Applications

• Portable electronic devices requiring EMI suppression
• Consumer electronics signal line protection
• Industrial control systems noise filtering

Procurement Notes

Verify the specific datasheet version before integration, as specifications may vary between manufacturing batches. Confirm RoHS compliance status directly with the supplier, as some sources indicate non-compliance while others suggest lead-free availability. Ensure the 1807 footprint matches the PCB design constraints. Check for obsolete status indicators, as lifecycle data suggests potential discontinuation risks that may affect long-term supply chain stability.

Selection Notes

Select this component when a third-order low-pass response is required within a minimal surface-mount area. The 2A current rating makes it suitable for power lines or high-current signal paths where standard filters might fail. Consider the 1000pF capacitance value for cutoff frequency requirements near the specified 110MHz range. Evaluate the 50V rating against the maximum operating voltage of the target circuit to ensure adequate safety margins during transient events.

Part Context

This component belongs to Panasonic's passive components category, specifically within the EMI/RFI filter subcategory. It is part of the CET series designed for surface-mount applications. The product line focuses on providing effective noise suppression solutions for modern electronic assemblies where size reduction and performance reliability are critical priorities for system designers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative LC T-type filters from other manufacturers based on identical capacitance, current rating, and package dimensions before substitution.
