YFF31PC1C474MT000N

Overview

The TDK YFF31PC1C474MT000N is a surface-mount feedthrough capacitor from the YFF-P series, designed for electromagnetic interference suppression. It features a capacitance of 0.47 µF with ±20% tolerance and a voltage rating of 16V DC. The component supports a maximum DC current of 2 A and exhibits a maximum DC resistance of 40 mΩ. Housed in a 1206 (3216 Metric) package with four PCB pads, it operates within a temperature range of -55°C to 125°C. Insertion loss specifications indicate attenuation of 40 dB across frequency ranges of 2 MHz to 1 GHz.

Feature Summary

• Utilizes feedthrough architecture for effective high-frequency noise suppression on power lines
• Supports high continuous DC current handling capabilities suitable for power applications
• Designed for surface-mount assembly to facilitate automated manufacturing processes

Applications

• Power line filtering in commercial electronic equipment

Procurement Notes

Verify the specific suffix codes against official TDK documentation to ensure correct capacitance and tolerance values. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference datasheet revisions to account for any potential parameter updates or packaging changes that may affect supply chain logistics.

Selection Notes

Select this component when space-constrained designs require high capacitance in a standard 1206 footprint. Ensure the operating voltage does not exceed 16V and the DC current remains below 2 A. Evaluate insertion loss characteristics against specific EMI frequency targets to confirm adequate attenuation performance for the intended application environment.
