Key Specifications

The attributes of the C2012X8L1C475K125AC are critical for understanding its suitability for specific design requirements:

• Apps. (Commercial Grade): This designation indicates that the capacitor is designed and tested to meet the rigorous demands of general commercial electronic products, ensuring reliability and performance in a broad spectrum of applications, from consumer electronics to industrial control systems.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components. Choosing a TDK component ensures adherence to stringent manufacturing standards and reliable performance.
• Feature (150°C): This highlights the capacitor’s ability to operate reliably at elevated temperatures, making it ideal for applications where heat generation is a concern or where components are exposed to high ambient temperatures.
• Tolerance (±10%): A capacitance tolerance of ±10% signifies the permissible deviation from the nominal 4.7µF capacitance. This level of precision is acceptable for many commercial applications where exact capacitance values are not hyper-critical but stability is important.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This specifies the physical dimensions of the surface-mount device. The 0805 package is a widely adopted standard, offering a good balance between component size and ease of handling during assembly, making it suitable for miniaturized circuits.
• Capacitance (4.7µF): This is the primary electrical property, indicating the component’s ability to store an electrical charge. A 4.7µF capacitance is substantial for many filtering, decoupling, and energy storage tasks in power supply lines or signal conditioning circuits.
• T(Max.) / mm (1.45): This refers to the maximum thickness of the component, which is important for mechanical design and ensuring proper fit within enclosures or under other components on a PCB.
• Temp. Chara. (X8L): The X8L temperature characteristic defines how the capacitance changes over a specified temperature range. For X8L, the capacitance change is within +15% to -40% over an operating temperature range of -55°C to +150°C, indicating stable performance even at extreme temperatures.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of capacitor. MLCCs are favored for their small size, high capacitance values, low ESR, and excellent high-frequency characteristics.
• Product Status (Production): This confirms that the component is currently in active mass production, ensuring long-term availability and support for new and existing designs.
• Rated Voltage [DC] / V (16): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. Operating within this limit is crucial for the longevity and reliability of the component.
• Cap.Change or Temp.Coef. (+15,-40%): This explicitly states the maximum percentage change in capacitance over the full operating temperature range, directly linked to the X8L characteristic.
• Operating Temp. Range / °C (-55 to 150): This specifies the full ambient temperature range within which the capacitor is designed to operate reliably, from extreme cold to very high heat, underscoring its robustness.
