As a passive component, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in electronic circuits. Its small form factor and robust construction make it an ideal choice for compact and critical automotive systems where space is at a premium and reliability is paramount.

Key Specifications

• Applications (Automotive Grade): This attribute signifies that the CGA2B2X7R1H221K050BA capacitor is specifically designed and tested to meet the stringent requirements of automotive electronics. This includes resistance to extreme temperatures, vibrations, and humidity, ensuring long-term reliability in vehicles.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrite products. Choosing a TDK component assures engineers of a product built to exacting standards with a strong reputation for 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 full compliance, meaning the capacitor has undergone rigorous testing to ensure its suitability and reliability in automotive environments, from engine compartments to infotainment systems.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose applications, indicating good precision for most circuit designs.
• L x W Size (1.0mm x 0.5mm [EIA 0402]): This denotes the physical dimensions of the capacitor. The 0402 EIA (Electronic Industries Alliance) package code is a very small surface-mount device (SMD) size, making it suitable for miniaturized electronic circuits where board space is critical.
• Capacitance (220pF): This is the fundamental electrical property of the capacitor, representing its ability to store an electrical charge. 220 picofarads (pF) is a relatively small capacitance value, typically used for high-frequency filtering, coupling, or timing applications.
• T(Max.) / mm (0.55): This indicates the maximum thickness of the component, which is 0.55mm. This thin profile is advantageous for designs requiring low-profile components, contributing to overall device slimness.
• Temperature Characteristic (X7R): X7R is a common dielectric material for ceramic capacitors, known for its stable performance across a wide temperature range. It offers a capacitance change of ±15% over its operating temperature range, making it suitable for many general-purpose and automotive applications where temperature stability is important.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the component as a Multi-Layer Ceramic Capacitor (MLCC), which are widely used due to their small size, high capacitance values for their size, and excellent high-frequency characteristics.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply for new and existing designs.
• Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 50V rating provides a good margin for many automotive 12V or 24V systems.
• 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 means the capacitance will not vary by more than 15% from its nominal value within the operating temperature limits.
• Operating Temp. Range / °C (-55 to 125): This specifies the full temperature range over which the capacitor is designed to operate reliably. The broad range from -55°C to 125°C is critical for automotive applications, which often experience extreme temperature fluctuations.
