• Capacitance: 47nF: This is the nominal capacitance value, indicating its ability to store 47 nanofarads of electrical charge. This value is suitable for various filtering, decoupling, and timing applications.
• T(Max.) / mm: 0.39: This refers to the maximum thickness of the component, which is 0.39mm. This ultra-thin profile further contributes to its suitability for compact designs.
• Temp. Chara.: X7R: X7R is a common dielectric material for ceramic capacitors, known for its stable performance over a wide temperature range. It offers a capacitance change of ±15% from -55°C to +125°C, making it ideal for general-purpose applications in varying thermal conditions.
• Component Type: Ceramic Capacitor (MLCC): Confirms its classification as a Multi-Layer Ceramic Capacitor, a widely used type due to its small size, high frequency response, and reliability.
• Product Status: Production: Indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply stability.
• Rated Voltage [DC] / V: 25: This is the maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown. A 25V rating is suitable for many low to medium voltage automotive control and sensor circuits.
• Cap.Change or Temp.Coef.: ±15%: This reiterates the capacitance change over the operating temperature range for the X7R dielectric, ensuring predictable performance under thermal variations.
• Operating Temp. Range / °C: -55 to 125: This specifies the full temperature range over which the capacitor is guaranteed to operate within its specified parameters. This broad range is critical for automotive applications, which must function reliably in extreme hot and cold conditions.
