Product Overview

YFF18PW0J474MT0H0N is a high-performance 3-terminal power line feedthrough filter from TDK's YFF-P series, featuring a 1608 (0603 inch) low-ESL (Equivalent Series Inductance) package. Engineered to tackle electromagnetic interference (EMI) in complex power lines, it offers ultra-wideband filtering and high-current capability, operating stably from -55℃ to +125℃. Compliant with RoHS and suitable for communication devices, consumer electronics, and industrial control, it is a core component for enhancing electromagnetic compatibility (EMC).

Key Features

• Ultra-Wideband Effective Filtering：Achieves ≥40dB insertion loss in the 2MHz to 2000MHz range, efficiently suppressing high-frequency and ultra-high-frequency interference for a clean power supply.
• High-Current Stable Operation：With a rated current of 4A, it supports continuous operation of medium-to-high-power devices, minimizing energy loss through low DC resistance to maintain filtering performance under high current.
• Low ESL Optimized Design：Reduces equivalent series inductance (ESL) through structural optimization, improving high-frequency signal transmission efficiency and minimizing signal distortion for high-speed digital circuits.
• Compact Package for High Adaptability：Adopts a 1608 micro SMD package (1.6mm×0.8mm×0.8mm), saving PCB space and enabling high-density integration, ideal for miniaturized and slim device designs.
• Wide Temperature Range Reliability：Operates reliably in -55℃ to +125℃, passing rigorous temperature cycle and vibration tests to ensure long-term stability in industrial-grade harsh environments.
