C2012X7R1C475K125AB

Overview

C2012X7R1C475K125AB is a high-quality multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is designed to store and release electrical energy, filter noise, and stabilize voltage in a wide range of electronic circuits. As a ceramic capacitor, it utilizes ceramic dielectric material between conductive plates, offering excellent performance characteristics such as high capacitance in a small form factor, good frequency response, and reliability. This particular TDK MLCC is a commercial-grade component, making it suitable for general-purpose applications where robust and consistent performance is required.

Key Specifications

• Apps. (Commercial Grade): This designation indicates that the capacitor is designed for general electronic applications, offering a balance of performance and cost-effectiveness. It is suitable for a broad spectrum of consumer and industrial electronics where extreme reliability requirements (like automotive or medical) are not primary.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Specifying TDK ensures a product from a trusted manufacturer with a reputation for innovation and reliability.
• Feature (General): This attribute further emphasizes its suitability for a wide array of standard electronic circuit designs, indicating it’s not specialized for niche applications but rather a versatile component.
• Tolerance (±10%): The capacitance value of 4.7μF can vary by ±10% from its nominal value. This tolerance level is common for general-purpose capacitors and is acceptable in many applications where precise capacitance is not critical, allowing for cost-effective manufacturing.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This specifies the physical dimensions of the surface-mount device (SMD) capacitor. An EIA 0805 package size is a common and widely used footprint, indicating a compact component suitable for miniaturized electronic assemblies. The dimensions are 2.0mm in length and 1.25mm in width.
• Capacitance (4.7μF): This is the primary electrical characteristic, indicating the capacitor’s ability to store charge. A capacitance of 4.7 microfarads (μF) is a relatively high value for an MLCC of this size, making it suitable for decoupling, filtering, and energy storage applications.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, which is 1.45mm. This dimension is crucial for PCB layout and ensuring proper clearance in compact designs.
• Temp. Chara. (X7R): X7R is a common dielectric material classification for ceramic capacitors. It indicates a stable dielectric with a capacitance change of ±15% over an operating temperature range of -55°C to +125°C. X7R capacitors are suitable for decoupling, bypass, and filtering applications where temperature stability is important but not as critical as C0G/NP0 dielectrics.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the product as a Multilayer Ceramic Capacitor, highlighting its construction and technology.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for new designs and mass production, ensuring long-term supply.
• Rated Voltage [DC] / V (16): This is the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. A 16V rating makes it suitable for common low-voltage digital and analog circuits.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance variation over the specified temperature range, directly linked to the X7R dielectric characteristic. It means the capacitance will not deviate by more than 15% from its nominal value within the operating temperature range.
• Operating Temp. Range / °C (-55 to 125): This specifies the ambient temperature range within which the capacitor is designed to operate reliably. A wide range from -55°C to +125°C makes it suitable for demanding industrial and outdoor applications, as well as standard commercial environments.
