• T(Max.) / mm (0.9): This refers to the maximum thickness of the component, which is 0.9mm. This dimension is crucial for mechanical design and ensuring proper fit within enclosures and under other components on a PCB.
• Temp. Chara. (X5R): X5R is a ceramic dielectric material class that offers a capacitance change of ±15% over an operating temperature range of -55°C to +85°C. This characteristic makes it suitable for general-purpose applications where stable performance across a moderate temperature range is required.
• Component Type (Ceramic Capacitor (MLCC)): Specifies that it is a Multi-Layer Ceramic Capacitor, which are highly popular due to their small size, high capacitance values, and excellent high-frequency performance.
• Product Status (Production): Indicates that the component is actively being manufactured and is available for purchase in volume, ensuring long-term supply for industrial and commercial applications.
• Rated Voltage [DC] / V (25): The maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. For the CGA3E3X5R1E105M080AB, a 25V rating makes it suitable for a wide range of low-voltage automotive and general electronic circuits.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change characteristic for the X5R dielectric, confirming that the capacitance will not vary by more than ±15% within its specified operating temperature range.
• Operating Temp. Range / °C (-55 to 85): The range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified performance characteristics. This broad range is typical for automotive-grade components, allowing operation in diverse environmental conditions.
