Key Specifications

The attributes of the CGJ3E2X7R2A152K080AA provide a comprehensive understanding of its capabilities and ideal use cases:

• Applications (High Reliability Grade): This designation signifies that the capacitor is engineered for environments where failure is not an option, such as critical automotive, industrial, or medical systems. It implies rigorous testing and adherence to stringent quality standards beyond standard commercial parts.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, particularly in the capacitor and inductor markets. Specifying TDK ensures a certain level of performance and manufacturing excellence.
• Feature (AEC-Q200Mid) & AEC-Q200 (YES): AEC-Q200 is a global standard for stress qualification of passive electronic components used in automotive applications. “AEC-Q200Mid” further specifies that it meets a mid-level qualification, suitable for many automotive subsystems where robust performance under varying conditions is crucial. This qualification is a strong indicator of its durability and reliability.
• Tolerance (±10%): This value indicates the permissible deviation of the actual capacitance from the nominal 1.5nF value. A ±10% tolerance is common for general-purpose and many high-reliability applications, providing a good balance between precision and cost.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The EIA 0603 standard size (0.06 x 0.03 inches) is a very common and compact footprint, allowing for high-density circuit board designs in miniaturized electronic devices.
• Capacitance (1.5nF): This is the nominal electrical charge storage capacity of the capacitor, measured in nanofarads (nF). A capacitance of 1.5nF is suitable for various filtering, coupling, and timing applications in electronic circuits.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is critical for mechanical design and ensuring proper fit within enclosures, especially in thin or space-constrained devices.
• Temp. Chara. (X7R) & Cap.Change or Temp.Coef. (±15%): X7R is a common dielectric material for ceramic capacitors, known for its relatively stable capacitance over a wide temperature range. The ±15% capacitance change over the operating temperature range (-55 to 125 °C) signifies that while there is some variation, it remains within acceptable limits for many industrial and automotive applications, unlike less stable dielectrics.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. Multi-Layer Ceramic Capacitors (MLCCs) are widely used due to their small size, high reliability, and excellent frequency characteristics.
• Product Status (Obsolete): While the component is obsolete, it means it is no longer in active production by the manufacturer. However, it may still be available through distributors for existing designs, repairs, or specific project requirements.
• Rated Voltage [DC] / V (100): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 100V rating makes it suitable for circuits with moderate voltage requirements.
• Operating Temp. Range / °C (-55 to 125): This specifies the ambient temperature range within which the capacitor is designed to operate reliably and meet its specified electrical characteristics. A wide range like -55°C to 125°C is characteristic of high-reliability and automotive-grade components.

Features and Benefits
