1206J0250153MXTE01

Overview

The Knowles Syfer 1206J0250153MXTE01 is a three-terminal X2Y integrated surface mount EMI filter capacitor. It features a capacitance of 15 nF with a tolerance of ±20% and a DC voltage rating of 25 VDC. The component utilizes an X7R dielectric material, ensuring stable performance across an operating temperature range from -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier structure for enhanced reliability. This device functions as both a capacitor and an EMI filter within a single compact footprint.

Feature Summary

• Integrates X2Y three-terminal architecture for simultaneous common-mode and differential-mode noise suppression
• Utilizes nickel barrier construction to improve solder joint integrity and mechanical durability
• Provides high-frequency electromagnetic interference filtering within a standard surface-mount form factor

Applications

• High-speed digital signal line protection
• Power supply input/output filtering
• EMI suppression in compact electronic assemblies

Procurement Notes

Verify the complete part number including the suffix MXTE01 to ensure correct terminal configuration and termination material. Confirm that the specific reel quantity matches production requirements. Cross-reference the datasheet for detailed impedance characteristics and thermal handling limits before finalizing procurement specifications.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering capabilities. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure the circuit operates within the specified 25 VDC limit and temperature range to maintain optimal capacitance stability and filter performance.

Part Context

This component belongs to the Knowles Syfer X2Y series, which specializes in integrated passive devices. The 1206J prefix indicates the 1206 case size and general product line classification. These devices are engineered to replace multiple discrete components, reducing board area and simplifying assembly processes for modern high-density electronics.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 15 nF capacitance, 25 V rating, and three-terminal X2Y topology. Verify that alternative parts support the same nickel barrier termination and X7R dielectric characteristics to maintain equivalent thermal and electrical performance.
