0805J0250681MJTE07

Overview

The Knowles Syfer 0805J0250681MJTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 680 pF with a DC voltage rating of 25 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. It is housed in an 0805 (2012 metric) case size and offers a tolerance of ±20%. This part is specifically engineered as a feed-through capacitor, providing superior electromagnetic interference filtering capabilities compared to standard MLCCs.

Feature Summary

• Feed-through architecture provides enhanced electromagnetic interference suppression
• C0G (NP0) dielectric ensures minimal capacitance variation over temperature and voltage
• High-reliability construction suitable for demanding electronic environments

Applications

• High-frequency signal filtering in communication systems
• Power supply line noise reduction in sensitive electronics
• Electromagnetic compatibility circuits in industrial equipment

Procurement Notes

Verify the specific termination configuration and lead frame material when sourcing this feed-through variant, as it differs structurally from standard parallel-plate MLCCs. Confirm that the PCB footprint accounts for the internal feed-through structure rather than simple end-terminal placement. Ensure the selected distributor sources directly from Knowles Syfer or authorized channels to guarantee authenticity and traceability for high-reliability applications.

Selection Notes

Select this component when superior RF attenuation is required within a compact 0805 footprint. The feed-through design offers lower parasitic inductance than standard capacitors, making it ideal for high-speed digital lines. Consider the ±20% tolerance if precise capacitance tuning is not critical. Evaluate thermal management requirements given the operating range extends to +125°C.

Part Context

This part belongs to the Knowles Syfer High Reliability MLCC family, which emphasizes robustness in harsh environments. The 'J' suffix typically denotes the 0805 case size, while '025' indicates the 25V rating. The 'MJTE' suffix specifies the particular termination and packaging details for this feed-through series, distinguishing it from general-purpose capacitors in the same voltage and capacitance class.

Replacement Considerations

Direct substitutes are limited due to the unique feed-through structure. Standard 0805 MLCCs like 0805J0250681GFT may fit physically but lack the integrated filtering performance. Verify if alternative feed-through capacitors from other manufacturers meet the specific impedance and current handling requirements before substitution.
