Key Specifications

• Applications (Commercial Grade): This designation indicates that the capacitor is engineered for use in standard commercial electronic products, where reliability and cost-effectiveness are balanced. It is suitable for a broad range of consumer electronics, industrial controls, and communication equipment, rather than highly specialized or extreme-environment applications.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its expertise in magnetic materials and electronic components. Their brand signifies a commitment to quality, innovation, and high manufacturing standards, ensuring the reliability and performance of this MLCC.
• Feature (Mid): The ‘Mid’ feature likely refers to its balanced performance characteristics, suitable for a wide range of general-purpose applications without being overly specialized for high-frequency or high-power tasks. It strikes a good balance between size, capacitance, and voltage rating.
• Tolerance (±5%): This specifies the maximum permissible deviation of the actual capacitance value from its nominal value (3.9nF). A ±5% tolerance is considered precise for many applications, ensuring that the component performs within expected parameters and contributes to stable circuit operation.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This indicates the physical dimensions of the surface-mount device (SMD) capacitor. The 0805 EIA standard size is very common, offering a good balance between miniaturization and ease of handling during automated assembly processes. Its compact footprint is ideal for space-constrained PCBs.
• Capacitance (3.9nF): This is the nominal electrical charge storage capacity of the capacitor, measured in nanofarads (nF). A 3.9nF capacitance is suitable for various signal coupling, decoupling, and filtering tasks in digital and analog circuits, particularly in mid-frequency ranges.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, 1.45mm. This dimension is crucial for mechanical design and ensuring proper fit within enclosures and clearances on a printed circuit board.
• Temperature Characteristic (C0G): C0G is a highly stable dielectric material class for ceramic capacitors. It signifies a very low change in capacitance over a wide temperature range, making it ideal for precision timing, filtering, and resonant circuits where temperature stability is critical.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs are known for their small size, low equivalent series resistance (ESR), good high-frequency performance, and cost-effectiveness, making them ubiquitous in modern electronics.
• Product Status (Production): This status indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply and support for new and existing designs.
• 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 ample headroom for many common 5V, 12V, and 24V power supply lines, ensuring robust operation.
• Cap. Change or Temp. Coef. (0±30ppm/°C): This specification, directly related to the C0G dielectric, indicates an extremely low capacitance change over temperature. A coefficient of 0±30ppm/°C means the capacitance will vary by only 30 parts per million per degree Celsius, highlighting its exceptional thermal stability.
• Operating Temp. Range / °C (-55 to 125): This defines the ambient temperature range within which the capacitor is designed to operate reliably and meet its specified performance characteristics. A wide range from -55°C to 125°C makes it suitable for diverse environments, including automotive, industrial, and outdoor applications.
