1206J0500472MXTE01

Overview

The Knowles Syfer 1206J0500472MXTE01 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 4.70 nF and a tolerance of ±20%. The component is rated for a DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. Termination consists of nickel barrier plating with 100% tin, designed for reliable SMD/SMT assembly.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Utilizes X7R ceramic dielectric material to maintain stable capacitance characteristics across the specified operating temperature range.
• Employed nickel barrier and 100% tin termination system to ensure robust solderability and mechanical integrity during surface mount processing.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for integrated circuits requiring clean supply voltages
• Signal integrity protection in high-speed digital data lines

Procurement Notes

Verify the complete part number including the suffix MXTE01 to ensure correct termination and packaging specifications. Confirm that the supplier provides official datasheets from Knowles Syfer to validate the X7R dielectric type and three-terminal construction. Ensure compatibility with standard reflow soldering profiles suitable for nickel-barrier terminations.

Selection Notes

Select this component when superior common-mode noise attenuation is required in space-constrained designs. The three-terminal structure offers lower parasitic inductance than standard MLCCs. Verify that the 50V rating and 4.7nF value align with the circuit's impedance matching requirements and thermal environment constraints.

Part Context

This component belongs to the Knowles Syfer EMI Filter series, specifically utilizing the 1206J base code for the 1206 footprint. The J indicates a 50V DC rating, while the 472 code denotes the 4.7nF capacitance value. The MXTE07/01 suffixes typically define the specific termination plating and reel packaging configuration.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 50V rating, 4.7nF capacitance, X7R dielectric, and three-terminal EMI filter topology. Verify equivalent insertion loss characteristics and terminal material compatibility before substitution.
