0805J1000122MXTE01

Overview

The Knowles Syfer 0805J1000122MXTE01 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 0805 (2012 metric) case size with C0G/NP0 dielectric characteristics, ensuring stable capacitance across varying temperatures. The component offers a nominal capacitance of 1200 pF with a tight tolerance of ±20%. It is rated for a DC voltage of 100 V and operates within a temperature range of -55°C to +125°C. The termination structure utilizes a nickel barrier with 100% tin plating, providing reliable solderability and mechanical integrity for high-reliability electronic assemblies.

Feature Summary

• Utilizes C0G/NP0 dielectric material for minimal capacitance variation over temperature and time.
• Features a robust nickel barrier and 100% tin termination system for enhanced solder joint reliability.
• Designed as a feed-through capacitor configuration to provide integrated filtering capabilities.

Applications

• High-frequency signal processing circuits requiring stable impedance characteristics.
• RF communication modules where low loss and precise capacitance are critical.
• Harsh environment electronics demanding operation across wide thermal ranges.

Procurement Notes

Verify the specific package variant and termination finish against the official datasheet before integration. Confirm that the feed-through pin configuration matches the PCB footprint design. Ensure compliance with RoHS directives and check for any specific handling requirements related to the nickel barrier construction during assembly processes.

Selection Notes

Select this component when a compact surface-mount solution is required for high-voltage applications up to 100 VDC. The C0G dielectric makes it suitable for resonant circuits and timing applications where stability is paramount. Consider the physical dimensions and terminal layout carefully to ensure compatibility with automated placement equipment and existing board designs.

Part Context

This part belongs to the Knowles Syfer general type MLCC series, specifically engineered for SMD/SMT applications. It represents a standard passive component used in modern electronics manufacturing. The product line emphasizes reliability and consistency, catering to industries such as telecommunications, industrial controls, and consumer electronics where long-term performance is essential.

Replacement Considerations

Direct substitutes must match the 0805 case size, 1200 pF capacitance, 100 V rating, and C0G dielectric. Verify that alternative parts support the same feed-through architecture if filtering functionality is required.
