• Temp. Chara. (X7R): X7R is a common dielectric material characteristic for ceramic capacitors. It signifies a stable capacitance change over a wide operating temperature range. For X7R, the capacitance change is typically within ±15% from -55°C to +125°C, making it ideal for automotive environments where temperature fluctuations are common.
• Component Type (Ceramic Capacitor (MLCC)): This confirms the fundamental type of the component, highlighting its multilayer ceramic construction which offers high volumetric efficiency and excellent high-frequency performance.
• 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 stability.
• Rated Voltage [DC] / V (100): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 100V rating provides a sufficient margin for many automotive power supply and signal conditioning circuits.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range, directly correlating with the X7R dielectric characteristic. It assures designers of predictable performance under varying thermal conditions.
• Operating Temp. Range / °C (-55 to 125): This specifies the full temperature range over which the capacitor is designed to operate reliably, from extreme cold to high heat. This broad range is essential for automotive applications that must function in diverse environmental conditions.
