0805J0500181MCTE01

Overview

The Knowles Syfer 0805J0500181MCTE01 is a three-terminal feed-through capacitor designed for surface-mount technology. It features a capacitance of 180 pF with a voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. It is housed in a compact 0805 (2012 metric) package with dimensions of 2.00 mm x 1.25 mm x 1.30 mm. The device supports a current rating of 300 mA and includes nickel barrier/100% tin terminations.

Feature Summary

• Three-terminal X2Y architecture provides simultaneous filtering of common-mode and differential-mode noise within a single compact footprint.
• Feed-through design integrates the ground connection directly through the center terminal, minimizing parasitic inductance for superior high-frequency attenuation.
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes, maintaining signal integrity in precision circuits.

Applications

• High-speed digital interface protection
• RF circuit decoupling
• EMI suppression in sensitive analog front-ends

Procurement Notes

Verify the specific suffix 'E01' against the manufacturer's latest datasheet to confirm termination plating and packaging details. Ensure the selected variant matches the required 300 mA current rating and 0805 footprint constraints for your PCB layout. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require effective EMI filtering without adding multiple discrete components. The three-terminal structure offers higher isolation compared to standard two-terminal MLCCs. Verify that the 50V DC rating exceeds the maximum peak voltage in the application to prevent dielectric breakdown.
