Its compact size and robust construction make it an ideal choice for circuits requiring reliable operation under varying environmental conditions, adhering to stringent industry standards.

Key Specifications

• Applications: Automotive Grade
  This attribute signifies that the capacitor is engineered and qualified for use in automotive electronics, where components must withstand harsh conditions such as extreme temperatures, vibrations, and electrical transients. Automotive-grade components are crucial for ensuring the safety and reliability of 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 reputation assures engineers of the component’s reliability and performance.
• Feature: AEC-Q200 General / AEC-Q200: YES
  AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. The “YES” indicates that this capacitor has successfully passed these rigorous tests, confirming its suitability and reliability for automotive environments.
• Tolerance: ±10%
  This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance means the capacitance can range from 423pF to 517pF. This level of precision is acceptable for many filtering and coupling applications where exact capacitance is not critically sensitive.
• L x W Size: 0.6mm x 0.3mm [EIA 0201]
  This describes the physical dimensions of the capacitor, corresponding to the EIA 0201 standard package size. This extremely small footprint is critical for miniaturized electronic devices and high-density PCB designs, allowing for more components in a smaller area.
• Capacitance: 470pF
  The nominal capacitance value of the component, measured in picofarads (pF). This value dictates the amount of charge the capacitor can store and is fundamental to its function in a circuit, whether for timing, filtering, or coupling.
• T(Max.) / mm: 0.33
  This indicates the maximum thickness of the component, which is 0.33mm. This thin profile is advantageous for applications where vertical space is limited, contributing to overall device slimness.
• Temperature Characteristic: X7R
  X7R is a common dielectric material characteristic for ceramic capacitors. It indicates a relatively stable capacitance over a wide temperature range, specifically ±15% capacitance change from -55°C to +125°C. This makes X7R capacitors suitable for general-purpose applications where temperature stability is important but not as critical as C0G/NP0.
• Component Type: Ceramic Capacitor (MLCC)
  This confirms the fundamental nature of the component as a Multilayer Ceramic Capacitor, known for its small size, high-frequency performance, and reliability.
• Product Status: Production
  This indicates 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: 16
  This is the maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown. Operating within this voltage rating is crucial for the component’s longevity and reliable performance.
• Cap. Change or Temp. Coef.: ±15%
  This reiterates the capacitance change over the specified operating temperature range for the X7R dielectric, confirming that the capacitance will not deviate by more than ±15% from its nominal value within that range.
• Operating Temp. Range / °C: -55 to 125
  This defines the full temperature range over which the capacitor is designed to operate reliably. The wide range from -55°C to 125°C is characteristic of automotive-grade components, allowing them to function in extreme hot and cold environments.
