Key Specifications

• Applications: Automotive Grade
  This attribute signifies that the capacitor is specifically engineered and tested to meet the rigorous standards required for automotive electronics. Components designated as ‘Automotive Grade’ must withstand extreme temperatures, vibrations, and electrical stresses commonly found in vehicles, ensuring long-term reliability and safety in critical systems.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand presence assures engineers of the component’s reliability, performance, and adherence to global manufacturing standards.
• Feature: AEC-Q200 General
  AEC-Q200 is a global standard for stress test qualification for passive components used in automotive applications. ‘General’ indicates that this capacitor meets the baseline requirements of this standard, confirming its suitability for use in automotive circuits where high reliability is crucial.
• AEC-Q200: YES
  This explicit confirmation reiterates that the component has successfully passed the qualification tests outlined by the Automotive Electronics Council’s AEC-Q200 standard, making it a reliable choice for automotive designs.
• Tolerance: ±20%
  The capacitance tolerance specifies the permissible deviation from the nominal capacitance value. A ±20% tolerance means the actual capacitance can range from 1.2μF to 1.8μF. This level of tolerance is common for general-purpose decoupling and filtering applications where precise capacitance is not overly critical, but stability across a range is important.
• L x W Size: 3.2mm x 1.6mm [EIA 1206]
  This describes the physical dimensions of the surface-mount component. The 3.2mm x 1.6mm size corresponds to the EIA 1206 standard package code, which is a widely recognized footprint for surface-mount devices. This size offers a balance between component density and ease of handling during manufacturing.
• Capacitance: 1.5μF
  This is the nominal electrical charge storage capacity of the capacitor. A capacitance of 1.5 microfarads (μF) is suitable for various applications, including power supply filtering, signal coupling/decoupling, and timing circuits, providing substantial charge storage for its size.
• T(Max.) / mm: 1.9
  This indicates the maximum thickness of the component, which is 1.9 millimeters. This dimension is crucial for mechanical design considerations, especially in space-constrained applications, ensuring proper fit and clearance on a printed circuit board.
• Temperature Characteristic: X5R
  X5R is a common dielectric material classification for ceramic capacitors. It indicates that the capacitance change over the operating temperature range (-55°C to +85°C) will not exceed ±15% of its nominal value. This characteristic makes X5R capacitors suitable for general-purpose applications where moderate temperature stability is acceptable.
• Component Type: Ceramic Capacitor (MLCC)
  This identifies the fundamental type of capacitor. MLCCs are known for their small size, low equivalent series resistance (ESR), low equivalent series inductance (ESL), and excellent high-frequency performance, making them ideal for a wide range of modern electronic circuits.
• Product Status: Production (NRND)
  NRND stands for ‘Not Recommended for New Designs.’ While the component is still in production and available for existing designs, manufacturers typically advise against using it in new projects, often due to newer, more optimized alternatives being available. However, for current designs, it remains a viable and supported part.
• 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 makes this capacitor suitable for many low to medium voltage automotive and general electronic applications.
• Cap. Change or Temp. Coef.: ±15%
  This reiterates the capacitance change over temperature, specifically for the X5R dielectric. It means that within its specified operating temperature range, the capacitance will not deviate by more than ±15% from its value at room temperature, ensuring predictable performance.
• Operating Temp. Range / °C: -55 to 85
  This specifies the ambient temperature range within which the capacitor is designed to operate reliably. The wide range from -55°C to +85°C is typical for automotive-grade components, allowing them to function effectively in diverse environmental conditions, from extreme cold starts to hot engine compartments.

Features and Benefits

• Automotive Grade Reliability: Designed and qualified to AEC-Q200 standards, ensuring exceptional reliability and performance in demanding automotive environments, including resistance to temperature extremes, vibration, and humidity.
• Stable Capacitance (X5R Dielectric): The X5R temperature characteristic provides a capacitance change of only ±15% across a wide operating temperature range of -55°C to +85°C, ensuring consistent circuit performance under varying thermal conditions.
• Compact EIA 1206 Package: The 3.2mm x 1.6mm footprint offers a balance between miniaturization and ease of assembly, making it suitable for high-density PCBs while remaining manageable for standard pick-and-place processes.
• High Capacitance in a Small Form Factor: With a 1.5μF capacitance at 25V, this MLCC provides significant charge storage and filtering capabilities in a compact package, optimizing board space without compromising electrical performance.
• TDK Quality Assurance: Manufactured by TDK, a globally recognized leader in electronic components, guaranteeing high-quality materials, precise manufacturing, and consistent performance, reducing the risk of field failures.
