EXC-14CE900X

Common Mode Chokes Overview

The EXC-14CE900X is a common mode noise filter from the Panasonic EXC-14CE series, designed for surface mount technology in a compact 0302 (0806 metric) package. It provides an impedance of 90 Ohms at a test frequency of 100 MHz with a tolerance of ±20%. The component features a maximum DC resistance of 2.5 Ohms and operates within a temperature range of -40°C to +85°C. Its physical dimensions are 0.85 mm in length, 0.65 mm in width, and 0.45 mm in height.

Common Mode Chokes Feature Summary

• Electromagnetic shielding design prevents leakage magnetic flux
• Robust multilayer sintered structure ensures high reliability during reflow soldering
• High-Q impedance characteristics for effective noise suppression

Common Mode Chokes Applications

• Noise countermeasures for USB 2.0 high-speed differential data lines
• Interference protection for LVDS high-speed differential data lines
• Common mode filtering in AV products such as LCD TVs and DVD/Blu-ray drives
• Signal integrity enhancement in communication devices including smartphones

Common Mode Chokes Procurement Notes

Verify the specific suffix 'X' against official Panasonic documentation to confirm packaging configuration, as suffixes may indicate reel or cut tape variations. Ensure compatibility with RoHS directives if required by the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current production status and availability constraints before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require a 0302 footprint for common mode noise suppression. The 90 Ohm impedance rating is suitable for high-speed differential interfaces like USB 2.0 and LVDS. Consider the low profile of 0.45 mm for thin device applications. Verify that the 2.5 Ohm DC resistance meets the current carrying requirements of the specific circuit trace being protected.

Common Mode Chokes Part Context

This component belongs to the EXC-14CE series of common mode chokes manufactured by Panasonic Industry. The series utilizes electromagnetic shielding technology to contain magnetic fields, distinguishing it from unshielded alternatives. It is categorized under coupled inductors and chokes, specifically engineered for suppressing common mode noise in compact electronic assemblies without compromising signal integrity.
