YFF15AC0J105MT0Q0E

Overview

The YFF15AC0J105MT0Q0E is a three-terminal feedthrough capacitor from the TDK YFF-AC series, designed for surface mount assembly. It features a capacitance of 1 µF with a ±20% tolerance and a rated voltage of 6.3V DC. The component supports a maximum DC current of 2 A and exhibits a maximum DC resistance of 30 mΩ. Housed in a compact 0402 (1005 Metric) package measuring 1.00mm x 0.50mm with a maximum height of 0.4mm, it provides an insertion loss of 40dB across the 1MHz to 2.6GHz frequency range. Qualified under AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.

Procurement Notes

Verify the specific suffix MT0Q0E to confirm AEC-Q200 automotive qualification and the 3-pad terminal configuration. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, as availability varies by distributor. Confirm RoHS3 compliance status during procurement to meet environmental regulations.

Selection Notes

Select this component when space-constrained designs require high capacitance values in a 0402 package. It is suitable for applications demanding high DC current handling capability alongside effective EMI suppression. Consider the low DC resistance for minimizing power loss in power delivery networks. Verify that the 6.3V rating aligns with the circuit's operating voltage margins.

Part Context

This component belongs to the TDK YFF-AC series of feedthrough capacitors, which are engineered for high-performance EMI filtering in compact form factors. The series is specifically tailored for automotive and industrial applications requiring robust noise suppression. The YFF15AC0J105MT0Q0E variant integrates ceramic dielectric technology to achieve stable performance across wide temperature ranges.

Replacement Considerations

Check for direct substitutes within the YFF-AC series with identical capacitance and voltage ratings. Verify that alternative components maintain the same 0402 footprint and 3-terminal configuration to ensure PCB compatibility. Confirm that replacement parts also hold AEC-Q200 qualification if used in automotive contexts.
