Key Specifications

The attributes of the C2012X5R1E106K125AB provide a detailed insight into its capabilities and suitability for various designs:

• Apps. (Commercial Grade): This designation indicates that the capacitor is engineered for use in standard commercial electronic products, where reliability and cost-effectiveness are key considerations. It is not specifically rated for automotive or high-reliability military applications, but offers robust performance for general electronics.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Choosing a TDK component ensures a certain level of manufacturing excellence and reliability.
• Feature (General): This signifies that the capacitor is a standard, versatile component suitable for a broad range of common circuit functions rather than specialized applications like high-frequency RF or power factor correction.
• Tolerance (±10%): The capacitance value of 10μF can vary by ±10% from its nominal value. This tolerance is common for general-purpose capacitors and is acceptable in most commercial applications where precise capacitance is not critical.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The 0805 package size is a very common and widely used footprint, offering a good balance between component density and ease of handling during assembly.
• Capacitance (10μF): This is the primary electrical characteristic, indicating the component’s ability to store an electrical charge. A 10μF capacitance is substantial for an MLCC of this size, making it suitable for power supply decoupling, filtering low-frequency noise, and timing circuits.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, which is 1.45mm. This dimension is important for PCB layout and ensuring proper clearance in compact designs.
• Temp. Chara. (X5R): X5R is a ceramic dielectric material classification that denotes a capacitance change of ±15% over an operating temperature range of -55°C to +85°C. This characteristic makes it suitable for applications where moderate temperature stability is acceptable.
• Component Type (Ceramic Capacitor (MLCC)): This confirms it is a Multilayer Ceramic Capacitor, known for their compact size, high capacitance values for their footprint, and excellent high-frequency performance compared to other capacitor types.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply for new and existing designs.
• Rated Voltage [DC] / V (25): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. Operating within this voltage rating is crucial for the capacitor’s longevity and reliability.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over temperature, specifically for the X5R dielectric, meaning the capacitance can vary by up to 15% from its nominal value across the specified operating temperature range.
• Operating Temp. Range / °C (-55 to 85): This defines the ambient temperature range within which the capacitor is designed to operate reliably and meet its specified electrical characteristics.

Features and Benefits
