Key Specifications

• Applications: Automotive Grade
  This designation signifies that the capacitor is specifically designed and tested to meet the rigorous demands of automotive electronics, ensuring reliable operation in harsh environments characterized by temperature extremes, vibration, and electrical transients.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and advanced electronic devices. Their brand signifies innovation, reliability, and precision engineering.
• Feature: AEC-Q200 MidGlue
  AEC-Q200 is a critical stress test qualification for passive electronic components used in automotive applications. The “MidGlue” feature refers to a specific internal construction or manufacturing process that enhances the component’s mechanical robustness and reliability, particularly under thermal cycling and vibration stress.
• AEC-Q200: YES
  Confirmation that the component fully complies with the AEC-Q200 standard, making it suitable for use in automotive systems where component reliability is non-negotiable for safety and performance.
• Tolerance: ±5%
  This indicates that the actual capacitance value of the component will be within ±5% of its nominal 68pF value. A tighter tolerance is crucial for precision circuits where exact capacitance values are critical for circuit performance and stability.
• L x W Size: 1.6mm x 0.8mm [EIA 0603]
  This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The EIA 0603 standard size is widely used in compact electronic designs, allowing for high-density PCB layouts and miniaturization of electronic products.
• Capacitance: 68pF
  The nominal capacitance value, measured in picofarads (pF), represents the component’s ability to store electrical charge. A 68pF capacitor is typically used in high-frequency filtering, resonant circuits, and coupling/decoupling applications.
• T(Max.) / mm: 0.95
  This denotes the maximum thickness of the component, which is 0.95mm. This dimension is important for mechanical design considerations, ensuring proper fit within enclosures and clearance on printed circuit boards.
• Temperature Characteristic: C0G
  C0G (also known as NP0) is one of the most stable dielectric materials for ceramic capacitors. It exhibits negligible change in capacitance over a wide temperature range and has very low dissipation factor, making it ideal for precision timing, filtering, and resonant circuits where temperature stability is critical.
• Component Type: Ceramic Capacitor (MLCC)
  This confirms it is a Multi-Layer Ceramic Capacitor, known for its small size, high reliability, and excellent performance at high frequencies. MLCCs are the most widely used type of capacitor in modern electronics.
• Product Status: Production
  Indicates that the component is actively being manufactured and is available for mass production, ensuring long-term supply and support for new and existing designs.
• Rated Voltage [DC] / V: 100
  The maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown. A 100V rating provides a substantial margin for many automotive and industrial applications, enhancing reliability.
• Cap. Change or Temp. Coef.: 0±30ppm/°C
  This specifies the temperature coefficient of capacitance, indicating how much the capacitance changes with temperature. A value of 0±30ppm/°C for C0G is exceptionally low, meaning the capacitance remains highly stable across its operating temperature range, which is crucial for precision applications.
• Operating Temp. Range / °C: -55 to 125
  The range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified performance characteristics. This wide range is typical for automotive-grade components, allowing operation in extreme hot and cold conditions.
