Key Specifications

The attributes of the CGA3E3X7R1H154K080AB are meticulously engineered to meet stringent performance requirements:

• Applications (Automotive Grade): This designation signifies that the capacitor is specifically designed and tested to withstand the harsh environmental conditions prevalent in automotive electronics, including extreme temperatures, vibrations, and electrical transients. It ensures long-term reliability in critical vehicle systems.
• Brand (TDK): TDK is a globally recognized manufacturer known for its high-quality and innovative electronic components. Choosing a TDK component assures engineers of reliable performance and adherence to international standards.
• Feature (AEC-Q200 General) & AEC-Q200 (YES): AEC-Q200 is a global standard for stress test qualification for passive components used in automotive applications. The ‘YES’ indicates full compliance, guaranteeing that the component has undergone rigorous testing for reliability in automotive environments, which is crucial for safety-critical systems.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for X7R dielectric types, providing a good balance between precision and cost-effectiveness for many applications.
• 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 0603 EIA standard size is a very common and compact footprint, enabling high-density circuit board designs, which is vital for miniaturization in modern electronics.
• Capacitance (150nF): This is the nominal electrical charge storage capacity of the capacitor, expressed in nanofarads (nF). A 150nF capacitance is suitable for various filtering, coupling, and bypass applications.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is important for mechanical design and clearance considerations in compact assemblies.
• Temperature Characteristic (X7R): X7R is a common dielectric material for ceramic capacitors, known for its stable performance across a wide temperature range. It guarantees that the capacitance change over the operating temperature range will be within ±15%, making it suitable for general-purpose applications where temperature stability is important but not as critical as C0G/NP0.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the fundamental type of component. MLCCs (Multi-Layer Ceramic Capacitors) are favored for their small size, high frequency performance, and reliability.
• Product Status (Production): This confirms 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 (50): This is the maximum DC voltage that can be continuously applied across the capacitor without risk of dielectric breakdown. A 50V rating provides ample margin for many automotive and industrial applications.
• Cap. Change or Temp. Coef. (±15%): This reiterates the capacitance stability over temperature for the X7R dielectric, indicating that the capacitance will not deviate by more than ±15% from its nominal value within the specified operating temperature range.
• Operating Temp. Range / °C (-55 to 125): This specifies the full range of ambient temperatures over which the capacitor is designed to operate reliably. A range from -55°C to 125°C is characteristic of automotive-grade components, ensuring functionality in extreme hot and cold conditions.
