0805J0250183MXTE01

Overview

The Knowles Syfer 0805J0250183MXTE01 is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 0.018 µF with a ±20% tolerance and a DC voltage rating of 25 VDC. The component utilizes an X7R dielectric material, ensuring stable performance across a wide operating temperature range from -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it provides a compact solution for EMI filtering applications requiring reliable pass-through signal integrity.

Feature Summary

• Integrated feedthrough architecture enables direct signal path integration without additional mounting hardware
• X7R ceramic dielectric maintains consistent electrical characteristics across extended industrial temperature ranges
• Compact 0805 surface-mount footprint facilitates automated assembly and dense PCB layout configurations

Applications

• High-speed data line EMI filtering in telecommunications equipment
• Signal conditioning and noise suppression in automotive electronic control units
• Power supply input/output decoupling in industrial control systems
• RF interference mitigation in medical diagnostic instrumentation

Procurement Notes

Verify the complete part number including the suffix against official manufacturer catalogs to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference distributor datasheets with the original Knowles Syfer documentation to validate technical parameters and availability constraints.

Selection Notes

Select this component when board space is limited but effective high-frequency noise attenuation is required on signal lines. The X7R dielectric offers a balance of volumetric efficiency and temperature stability suitable for general-purpose filtering. Ensure the operating voltage remains within the 25 VDC rating and consider the thermal environment relative to the specified -55°C to +125°C range during circuit design.

Part Context

This component belongs to the Knowles Syfer 0805J series of feedthrough capacitors, which are engineered for superior electromagnetic interference suppression compared to standard MLCCs. The series integrates the capacitor element directly into the conductor path, providing low parasitic inductance. This specific model represents a standard capacitance value within the broader family of high-reliability SMT filter components.

Replacement Considerations

Direct substitutes include other 0805 feedthrough capacitors with matching 0.018 µF capacitance, 25 VDC rating, and X7R dielectric. Verify that alternative parts maintain identical physical dimensions and terminal configuration to ensure mechanical compatibility. Check for equivalent frequency response characteristics and insertion loss specifications to guarantee functional parity in the target application.
