0805Y1000183MXTE01

Overview

The Knowles Syfer 0805Y1000183MXTE01 is a surface-mount feed-through capacitor with a capacitance of 0.018 µF and a DC voltage rating of 100 V. It utilizes X7R dielectric material and offers a tolerance of ±20%. The component features a 0805 (2012 metric) package size, specifically measuring 2.00 mm in length and 1.25 mm in width. Designed for high-frequency noise suppression, it supports a current rating of 300 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated pass-through architecture enables direct signal path routing through the capacitor body for efficient EMI filtering.
• Flexible termination technology accommodates board bending and thermal cycling stress to enhance mechanical reliability.
• X7R ceramic dielectric provides stable capacitance performance across a wide industrial operating temperature range.

Applications

• High-speed digital signal line filtering in communication equipment
• EMI suppression in compact consumer electronics assemblies
• Power integrity management in space-constrained mobile devices

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference the specific datasheet revision to validate electrical parameters against your design constraints. Ensure storage conditions meet manufacturer guidelines to prevent degradation of the flexible terminations before soldering.

Selection Notes

Select this component when board space is limited and a feed-through topology is required for optimal noise reduction. The 0805 footprint allows for dense PCB layouts while maintaining robust mechanical performance. Consider the X7R dielectric characteristics for applications requiring moderate capacitance stability over temperature variations. Evaluate the 300 mA current handling capability against the maximum expected signal or power currents in the circuit.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ series, which specializes in MLCCs with proprietary flexible terminations. The series is engineered to withstand significant board flexing and thermal shock without cracking. The 0805Y base designation indicates the standard 0805 case size family within the Syfer portfolio, offering various voltage ratings and dielectric options for diverse electronic applications.

Replacement Considerations

Direct substitutes must match the 0805 feed-through form factor, 100V rating, and 0.018µF capacitance. Verify that alternative components support similar current handling and feature compatible flexible terminations if board flex resistance is critical. Check for equivalent AEC-Q200 qualification if automotive reliability standards apply to the end application.
