0805J0500273MJTE07

Overview

The Knowles Syfer 0805J0500273MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.027 µF with a tolerance of ±20% and a DC voltage rating of 50V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) package, it incorporates a nickel barrier and 100% tin termination system. This X2Y-style architecture integrates three terminals into a single compact footprint to minimize parasitic inductance.

Feature Summary

• Integrates three electrical connections within a standard two-terminal SMD footprint to reduce circuit board space requirements.
• Provides simultaneous common-mode and differential-mode noise attenuation through internal terminal interconnection.
• Utilizes X7R ceramic dielectric to maintain stable capacitance characteristics across the specified operating temperature range.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF interference suppression in communication modules

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required thermal endurance and voltage derating curves for the target application environment. Cross-reference the part number with official distributor catalogs to confirm availability status and compliance documentation.

Selection Notes

Select this component when space constraints prevent the use of discrete common-mode chokes or multiple capacitors. Evaluate the impedance profile at the target noise frequency to ensure effective attenuation. Confirm that the 50V rating provides adequate margin for the maximum peak voltage present in the circuit under all operating conditions.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which specializes in EMI suppression solutions. These devices are engineered to replace traditional LC filters by combining filtering and grounding functions in a single passive element. The series targets applications requiring robust noise reduction in compact electronic assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative manufacturers only if their datasheets explicitly match the pinout, capacitance value, voltage rating, and physical dimensions.
