Circuit feedthrough YFF

for power suppliessingle-elementfor electronics

Overview
TDK's YFF Series 3-terminal feed-through filter provides compact, high-frequency noise suppression on power lines by combining a low-ESL design with a 3-terminal configuration. It is intended to simplify decoupling strategies in high-speed electronic designs and reduce the number of MLCCs required for stable power delivery.

Key benefits

• Low ESL for improved attenuation at high frequencies
• 3-terminal feed-through layout for direct line filtering on PCBs
• Helps reduce the total count of MLCCs needed for decoupling
• Compact form factor suitable for dense, high-speed layouts

Applications

• Power-line noise suppression in high-speed digital and mixed-signal circuits
• EMI/RFI mitigation where PCB area or MLCC count is limited
• Decoupling simplification in power distribution networks of compact devices
