0805J0250183MJTE07

Overview

The Knowles Syfer 0805J0250183MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric with a capacitance of 18 nF and a DC voltage rating of 25 VDC. The component operates within a temperature range of -55°C to +125°C and maintains a tolerance of ±20%. Housed in an 0805 (2012 metric) package, it functions as an EMI filter with a current rating of 1 A.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering capabilities
• Utilizes X7R dielectric material for stable capacitance performance across the operating temperature range
• Designed specifically for high-frequency noise suppression in surface mount applications

Applications

• Electromagnetic interference filtering in electronic circuits
• High-frequency noise suppression in signal lines
• Power supply decoupling requiring common-mode noise reduction

Procurement Notes

Verify the complete part number including the suffix to ensure correct terminal configuration and termination finish. Confirm that the specific variant matches the required three-terminal EMI filter design rather than standard two-terminal capacitors. Cross-reference manufacturer documentation for detailed mechanical dimensions and soldering profiles to ensure compatibility with assembly processes.

Selection Notes

Select this component when circuit design requires integrated EMI filtering alongside standard decoupling functions. The three-terminal structure offers superior high-frequency attenuation compared to conventional MLCCs. Ensure the PCB layout accommodates the specific pad configuration required for the grounded center terminal to maximize filtering effectiveness.

Part Context

This component belongs to the Knowles Syfer series of high-reliability ceramic capacitors. The 0805J prefix indicates the 0805 case size and 25V rating, while the MJTE07 suffix denotes the specific three-terminal EMI filter construction with nickel barrier and tin terminations. It is distinct from standard two-terminal capacitors in the same family due to its specialized internal electrode arrangement.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology and 0805 footprint. Verify equivalent capacitance, voltage rating, and dielectric type. Standard two-terminal capacitors are not functional replacements for EMI filtering applications.
