Key Specifications

This TDK MLCC boasts several critical specifications that define its performance and suitability for various designs:

• Applications: Commercial Grade – This designation indicates that the capacitor is engineered to meet the rigorous demands of general commercial electronic products, ensuring reliability and consistent performance in non-automotive or non-military environments.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, ensuring that this capacitor benefits from extensive research, development, and stringent manufacturing standards.
• Feature: Mid150°CSoft – This unique feature highlights the capacitor’s ability to operate reliably at elevated temperatures up to 150°C, while also possessing a ‘soft’ termination, which helps to mitigate the risk of cracking due to thermal or mechanical stress on the PCB.
• Tolerance: ±10% – A capacitance tolerance of ±10% means the actual capacitance value will be within 10% of the nominal 68nF, which is a standard and acceptable range for many commercial and industrial applications, ensuring circuit functionality.
• L x W Size: 2.0mm x 1.25mm [EIA 0805] – This specifies the physical dimensions of the component. The 0805 EIA standard package is a very common surface-mount size, offering a balance between miniaturization and ease of handling during assembly.
• Capacitance: 68nF – This is the nominal electrical charge storage capacity of the component. A 68nF capacitor is commonly used for decoupling, filtering, and timing applications in various digital and analog circuits.
• T(Max.) / mm: 1.5 – This indicates the maximum thickness of the component, which is important for board layout and ensuring adequate clearance in compact designs.
• Temp. Chara.: X8R – The X8R dielectric material is a highly stable ceramic formulation that allows the capacitor to retain its capacitance within ±15% over an extended operating temperature range of -55°C to +150°C, making it ideal for high-temperature environments.
• Component Type: Ceramic Capacitor (MLCC) – MLCCs are known for their small size, high frequency performance, and excellent reliability, making them a preferred choice for modern electronic devices.
• Product Status: Production – This confirms that the C2012X8R2A683K125AE is an active and readily available part, ensuring long-term supply for new designs and existing production lines.
• Rated Voltage [DC] / V: 100 – This is the maximum DC voltage that can be continuously applied across the capacitor without risk of dielectric breakdown. A 100V rating provides a good margin for many common power supply and signal processing applications.
• Cap.Change or Temp.Coef.: ±15% – This reiterates the capacitance change over the full operating temperature range, directly tied to the X8R dielectric characteristic, ensuring predictable performance across temperature variations.
• Operating Temp. Range / °C: -55 to 150 – This wide operating temperature range signifies the capacitor’s robustness, allowing it to function reliably in extreme cold or hot conditions, which is critical for industrial and outdoor electronics.

Features and Benefits

• High-Temperature Stability: The X8R dielectric and 150°C operating temperature rating ensure reliable performance in demanding thermal environments, reducing the need for derating or specialized cooling.
• Robust Construction with Soft Termination: The ‘Mid150°CSoft’ feature enhances mechanical robustness, preventing cracking caused by thermal expansion differences between the component and the PCB, leading to increased product longevity.
• Compact 0805 Package: Its small footprint (2.0mm x 1.25mm) allows for high-density PCB designs, contributing to the miniaturization of electronic devices without compromising performance.
• Wide Application Versatility: Suitable for a broad range of commercial-grade applications, from general-purpose filtering to critical timing circuits, due to its stable capacitance and voltage rating.
