0805J0250123MXTE01

Overview

The Knowles Syfer 0805J0250123MXTE01 is a feed-through ceramic capacitor designed for surface mount technology. It features a capacitance of 0.012 µF with a voltage rating of 25 VDC and an X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and offers a tolerance of ±20%. Housed in an 0805 (2012 metric) package, it supports a maximum current of 300 mA. This device integrates filtering capabilities directly into the capacitor structure.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Provides electromagnetic interference suppression through internal conductive path design
• Utilizes X7R dielectric material for stable performance across wide temperature variations

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in compact electronic modules
• EMI suppression in portable devices requiring small form factor solutions

Procurement Notes

Verify the specific suffix MXTE01 against official Knowles Syfer documentation to confirm the feed-through variant characteristics. Ensure compatibility with PCB pad layouts designed for feed-through components rather than standard MLCCs. Confirm RoHS compliance status via the manufacturer's latest environmental declaration before integration.

Selection Notes

Select this component when board space constraints require combined filtering and capacitance functions. Compare thermal management requirements against the 300 mA current limit. Evaluate whether the 0805 footprint accommodates the specific terminal configuration required for feed-through operation versus traditional parallel plate designs.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. It addresses EMI challenges in dense circuit boards by embedding filter elements within the capacitor body. The XT designation indicates specific termination or packaging attributes defined by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify mechanical fit and electrical specifications with alternative feed-through capacitors from other manufacturers if sourcing issues arise.
