Key Specifications

• Applications: Automotive Grade
  This designation signifies that the capacitor is specifically engineered and tested to withstand the extreme conditions prevalent in automotive environments, including wide temperature variations, vibrations, and electrical transients. It ensures reliability in safety-critical and performance-critical vehicle systems.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices. Their brand signifies a commitment to innovation, reliability, and precision engineering in the electronics industry.
• Feature: AEC-Q200 General
  AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. “General” indicates that this component meets the baseline requirements of this standard, ensuring its suitability for non-safety-critical automotive functions.
• AEC-Q200: YES
  Explicitly confirming compliance with the AEC-Q200 standard, this attribute guarantees that the capacitor has undergone stringent testing for temperature cycling, humidity, vibration, and other environmental stresses, making it robust for automotive use.
• Tolerance: ±10%
  This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose and automotive applications, indicating a good balance between precision and cost-effectiveness.
• L x W Size: 2.0mm x 1.25mm [EIA 0805]
  This refers to the physical dimensions of the surface-mount component. The 0805 EIA (Electronic Industries Alliance) package size is a widely adopted standard, offering a balance between miniaturization and ease of handling during assembly, suitable for compact circuit designs.
• Capacitance: 1.5μF
  The capacitance value of 1.5 microfarads (µF) indicates the component’s ability to store electrical charge. This value is suitable for various filtering, decoupling, and energy storage applications in power supply lines and signal conditioning circuits.
• T(Max.) / mm: 1.45
  This denotes the maximum thickness of the component, which is 1.45 millimeters. This dimension is crucial for mechanical design considerations, especially in applications with strict height restrictions or when designing multi-layer PCBs.
• Temperature Characteristic: X7R
  X7R is a common dielectric material classification for ceramic capacitors, known for its stable capacitance over a wide temperature range. It specifies that the capacitance change will be within ±15% over the operating temperature range of -55°C to +125°C, making it suitable for demanding environments.
• Component Type: Ceramic Capacitor (MLCC)
  This identifies the fundamental type of component. MLCCs are favored for their small size, high capacitance values, low equivalent series resistance (ESR), and excellent high-frequency performance, making them versatile for modern electronics.
• Product Status: Production
  “Production” indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs, ensuring long-term supply and support.
• Rated Voltage [DC] / V: 25
  This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 25V rating is common for many low-voltage automotive and industrial control applications.
• Cap. Change or Temp. Coef.: ±15%
  This reiterates the capacitance stability over temperature, specifically for the X7R dielectric. It means the capacitance will not vary by more than ±15% from its nominal value across the full 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 and meet its specified performance characteristics. The wide range of -55°C to +125°C is typical for automotive-grade components, reflecting the extreme temperatures encountered in vehicle systems.
