ELW-CF800F01

Overview

The ELW-CF800F01 is a surface-mount LC noise filter manufactured by Panasonic Electronic Components. It functions as an ESD protection device and a second-order low-pass filter designed for data lines in mobile devices. The component operates within a temperature range of -20°C to 85°C and utilizes a 0402 (1005 Metric) package. It supports a current rating of 90mA and provides filtering at 800MHz.

Feature Summary

• Provides ESD protection for sensitive electronic circuits
• Functions as a second-order low-pass LC EMI/RFI filter
• Designed specifically for data line applications

Applications

• Data lines for mobile devices
• ESD protection circuits
• EMI/RFI filtering in compact electronics

Procurement Notes

Verify the obsolete lifecycle status before procurement planning, as availability may be limited or discontinued. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the 90mA current rating meets your specific circuit load needs. Check for authorized distributors offering remaining stock, as standard supply chains may not carry this item. Validate the operating temperature range against your environmental conditions.

Selection Notes

Select this component when space-constrained designs require integrated ESD protection and signal filtering. The 0402 package size suits high-density board layouts. Consider the 90mA current limit for low-power data lines. The 800MHz cutoff frequency defines its filtering characteristics. Verify compatibility with mobile device data interface standards.

Part Context

This part belongs to Panasonic's SMD L-C Noise/ESD Filter series. It falls under the broader category of EMI/RFI filters and LC networks. The product is distinct from Panasonic's supercapacitor offerings despite some distributor misclassifications. It serves as a specialized passive component for signal integrity management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct replacements should be sourced through authorized surplus channels or engineering evaluation of equivalent LC filter specifications.
