0805J1000271MCTE01

Overview

The Knowles Syfer 0805J1000271MCTE01 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a C0G (NP0) dielectric material, ensuring stable capacitance characteristics across varying temperatures and voltages. The component has a nominal capacitance of 270 pF with a tolerance of ±20%. It is rated for a DC voltage of 100 VDC and utilizes a three-terminal architecture to provide enhanced electromagnetic interference (EMI) filtering capabilities. The device operates within a temperature range of -55°C to +125°C and employs nickel barrier electrodes terminated with 100% tin.

Feature Summary

• Three-terminal EMI filter architecture for superior noise suppression
• C0G/NP0 dielectric for high stability and low loss
• Nickel barrier electrode construction with 100% tin terminations

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix 'E01' confirms the three-terminal configuration, as standard two-terminal variants may share similar base codes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB footprint design accommodates the distinct terminal layout of the three-terminal EMI filter structure rather than standard MLCC pads.

Selection Notes

Select this component when high-frequency noise attenuation is critical alongside standard capacitance requirements. The three-terminal design offers lower parasitic inductance compared to two-terminal equivalents. Consider the 20% tolerance if precise capacitance values are not required. Evaluate thermal management needs given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the Knowles Syfer general type MLCC family, specifically engineered for EMI filtering applications. The '0805' designation indicates the standard imperial case size, while the 'J' series typically denotes specific voltage and capacitance combinations within the product line. It represents a specialized variant within the broader ceramic capacitor portfolio, focusing on signal integrity rather than bulk energy storage.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing footprints if considering alternative manufacturers, as three-terminal layouts vary significantly between vendors.
