YFF21PC1E103M

Overview

The YFF21PC1E103M is a feed-through capacitor manufactured by TDK Corporation, designed for electromagnetic interference (EMI) suppression. It features a capacitance of 10000 pF with a tolerance of ±20% and a rated voltage of 25V. The component utilizes a surface-mount 0805 (2012 Metric) package configuration with a four-pad layout. This design facilitates effective high-frequency noise attenuation in compact electronic assemblies.

Feature Summary

• Provides three-terminal feed-through architecture for enhanced EMI filtering performance
• Utilizes a compact 0805 surface-mount footprint to support space-constrained designs
• Engineered for direct signal line integration to minimize parasitic inductance

Applications

• High-speed digital circuit noise suppression
• Power supply input/output filtering
• RF signal path interference mitigation

Procurement Notes

Verify the specific suffix codes against official TDK documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard reflow soldering profiles for the 0805 package. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a low-capacitance, high-frequency filter is required for sensitive signal lines. The 25V rating suits low-voltage logic and power applications. The four-pad 0805 form factor offers mechanical stability compared to two-terminal alternatives. Evaluate PCB trace impedance and thermal requirements to ensure optimal mounting and electrical performance within the target system environment.

Part Context

This component belongs to TDK's YFF series of feed-through capacitors, which are specialized passive components for EMI suppression. These devices integrate capacitor functionality with a grounded center terminal to provide superior high-frequency attenuation compared to standard two-terminal capacitors. The series is widely utilized in consumer electronics and industrial equipment requiring robust noise control.
