YFF31PC1C104MT009N

Overview

The TDK YFF31PC1C104MT009N is a surface-mount feed-through capacitor from the YFF-P series, designed for high-frequency noise suppression. It features a capacitance of 0.1 µF with ±20% tolerance and a rated voltage of 16V DC. The component supports a continuous current of 2 A and exhibits a maximum DC resistance of 40 mΩ. It provides an insertion loss of 40 dB across the 7 MHz to 1 GHz frequency range. The device operates within a temperature range of -55°C to 125°C and utilizes a 1206 (3216 Metric) package with four PCB pads.

Feature Summary

• Feed-through architecture providing low inductance path for effective high-frequency noise attenuation
• High current handling capability suitable for power line filtering applications
• Surface-mount design compatible with standard SMD assembly processes

Applications

• Noise suppression in digital logic circuits
• Power supply input filtering for integrated circuits
• EMI reduction in communication equipment signal lines

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance and REACH status prior to integration. Check for active production status as some listings indicate discontinuation. Ensure storage conditions maintain moisture sensitivity level 1 integrity before reflow soldering.

Selection Notes

Select this component when low parasitic inductance is critical for EMI performance above 10 MHz. The 1206 footprint offers a balance between current capacity and board space. Consider the 16V rating against peak transient voltages in the target circuit. Evaluate the 40 mΩ DCR impact on power loss if operating near the 2 A limit.

Part Context

This part belongs to the TDK YFF-P series of feed-through capacitors. These components utilize a unique internal structure that minimizes equivalent series inductance compared to standard MLCCs. The series is engineered specifically for suppressing electromagnetic interference in high-speed digital and RF environments where traditional capacitors may fail due to parasitic effects.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative feed-through capacitors based on specific impedance and current requirements.
