1206Y0250683MXTE07

Overview

The Knowles Syfer 1206Y0250683MXTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 68 nF with a tolerance of ±20%, rated at 25 VDC using X7R dielectric material. The component utilizes the FlexiCap™ series architecture, incorporating flexible terminals and a nickel barrier to enhance mechanical robustness against board flexure. Housed in a standard 1206 (3216 metric) package, it operates within a temperature range of -55°C to +125°C. This device is classified as a Class 2 capacitor intended for demanding electronic applications requiring superior durability.

• Features an integrated nickel barrier structure to improve reliability and protect internal electrodes during operation.
• Constructed with X7R ceramic dielectric to maintain stable capacitance characteristics across a wide industrial temperature range.

Applications

• Board-flex sensitive electronic assemblies
• High-reliability industrial equipment circuits
• Automotive electronics modules

Procurement Notes

Verify the specific suffix configuration when sourcing this component, as ordering codes may denote variations in termination plating or packaging formats that do not alter the fundamental electrical function. Confirm that the requested part matches the exact three-terminal EMI filter specification if applicable to your design requirements. Ensure compatibility with automated pick-and-place machinery due to the reel packaging format. Cross-reference the manufacturer datasheet for precise handling instructions regarding moisture sensitivity levels before assembly processing.

Selection Notes

Select this component when application environments involve significant mechanical vibration or thermal cycling that could cause standard terminations to fracture. The inclusion of the nickel barrier provides enhanced protection compared to standard MLCCs, making it suitable for critical infrastructure. Consider the 1206 footprint constraints and the specific voltage derating requirements associated with X7R dielectrics at elevated temperatures. Evaluate the trade-off between the higher cost of specialized FlexiCap technology versus standard general-purpose capacitors based on system reliability targets.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ product line, which specializes in robust multilayer ceramic capacitors engineered for harsh environments. The '1206Y' prefix indicates a 1206 case size with specific high-reliability construction standards. The 'MXTE' suffix typically denotes the specific terminal configuration and barrier layer implementation unique to this series. These devices are positioned above standard commercial grade parts, targeting sectors where failure rates must be minimized through superior mechanical design.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 68 nF capacitance, 25 V rating, and X7R dielectric type. Crucially, replacements should offer comparable FlexiCap™ flexibility or equivalent mechanical reinforcement to prevent solder joint fatigue. Verify that any alternative part includes similar barrier protection if the original design relies on it for electrode integrity. Generic MLCCs lacking flexible terminations may fail under identical mechanical stress conditions.

FAQ

What is the primary mechanical advantage of the FlexiCap™ feature in this capacitor?

The FlexiCap™ feature utilizes flexible soft terminals that absorb mechanical strain, significantly reducing the risk of solder joint cracking caused by printed circuit board flexure or vibration.

Does the nickel barrier affect the electrical performance of the capacitor?

The nickel barrier is a structural component designed to protect the internal electrodes and enhance reliability; it does not alter the fundamental capacitance or voltage rating specifications defined by the X7R dielectric.
