0805J0250122MJTE07

Overview

The Knowles Syfer 0805J0250122MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 1200 pF with a tolerance of ±20%, rated at a DC voltage of 25 V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it employs a nickel barrier electrode structure terminated with 100% tin. This configuration provides robust EMI filtering capabilities and mechanical durability suitable for demanding electronic environments.

Feature Summary

• Utilizes C0G/NP0 dielectric for exceptional capacitance stability and low loss characteristics
• Features a nickel barrier internal electrode structure for enhanced reliability
• Designed specifically for EMI filtering applications within compact footprints
• Constructed with 100% tin terminations compatible with standard soldering processes

Applications

• High-reliability EMI suppression circuits
• Critical automotive electronics requiring robust passive components
• Industrial control systems demanding stable capacitance under thermal stress
• Aerospace and defense communication equipment

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm terminal finish and packaging details. Ensure compatibility with existing PCB footprints and reflow profiles. Cross-reference the full part number with current datasheets to validate availability status and compliance certifications before finalizing procurement plans.

Selection Notes

Select this component when a stable C0G/NP0 characteristic is required in a 0805 footprint for EMI filtering. The nickel barrier construction offers superior reliability compared to standard palladium-silver electrodes. Consider the 25V rating and 1200pF value for coupling or decoupling tasks where minimal capacitance drift is critical over wide temperature ranges.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC portfolio, often associated with AEC-Q200 qualification standards. The 'J' indicates the 0805 case size, while '025' denotes the 25V rating. The 'MJTE07' suffix typically specifies the termination system and reel packaging format, distinguishing it from general-purpose variants within the broader Syfer lineup.

Replacement Considerations

Direct substitutes include other 0805 C0G capacitors with matching 25V and 1200pF ratings. Verify that alternative parts also feature nickel barrier electrodes if EMI filtering and long-term reliability are primary concerns. Ensure dimensional compatibility and electrical specifications align precisely with the original design requirements.
