Its compact size and robust construction make it an ideal choice for space-constrained and critical applications.

Key Specifications

• Apps. (Automotive Grade): This attribute signifies that the capacitor is specifically designed and qualified for use in automotive electronics. Components designated as ‘Automotive Grade’ undergo stringent testing to ensure reliable operation under the extreme conditions (temperature, vibration, humidity) typically found in vehicles, making them suitable for critical safety and performance systems.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Choosing a TDK component ensures a product backed by extensive research, development, and manufacturing expertise.
• Feature (AEC-Q200 General): This indicates compliance with the AEC-Q200 standard, which is a fundamental stress test qualification for passive electronic components used in automotive applications. ‘General’ implies it meets the core requirements for a wide range of automotive uses.
• AEC-Q200 (YES): Explicitly confirms that the component is qualified to the AEC-Q200 standard, providing assurance of 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 is common for X7R dielectric capacitors, indicating a reasonable level of precision for general filtering and coupling applications.
• L x W Size (0.6mm x 0.3mm [EIA 0201]): This refers to the physical dimensions of the capacitor. The EIA 0201 package size is extremely small, measuring 0.6mm in length and 0.3mm in width. This miniature footprint is crucial for modern, compact electronic designs where board space is at a premium, enabling higher component density.
• Capacitance (100pF): The nominal capacitance value of the component is 100 picofarads. This value determines the amount of charge the capacitor can store and is critical for frequency-dependent applications such as filtering, timing, and resonant circuits.
• T(Max.) / mm (0.33): This indicates the maximum thickness of the component, which is 0.33mm. This low profile is beneficial for designs requiring minimal vertical clearance.
• Temp. Chara. (X7R): X7R is a common dielectric material for ceramic capacitors, known for its stable performance over a wide temperature range. It is considered a ‘temperature stable’ dielectric, suitable for applications where capacitance change with temperature needs to be controlled.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the component as a Multi-Layer Ceramic Capacitor (MLCC), which consists of multiple layers of ceramic dielectric and metal electrodes stacked alternately. MLCCs are widely used due to their small size, high capacitance values, and excellent high-frequency characteristics.
• Product Status (Production): This confirms that the CGA1A2X7R1H101K030BA is actively being manufactured and is readily available for purchase, ensuring long-term supply for design and production cycles.
• Rated Voltage [DC] / V (50): The maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown is 50 volts. Selecting a capacitor with a rated voltage significantly higher than the circuit’s operating voltage is crucial for reliability and longevity.
• Cap.Change or Temp.Coef. (±15%): For X7R dielectrics, this specifies that the capacitance can change by a maximum of ±15% over the full operating temperature range (-55°C to 125°C). This characteristic is important for designers to consider when precise capacitance values are critical across varying temperatures.
• Operating Temp. Range / °C (-55 to 125): This defines the ambient temperature range within which the capacitor is designed to operate reliably. The wide range from -55°C to 125°C further underscores its suitability for demanding automotive and industrial environments.

Features and Benefits

• Automotive Grade Reliability: Fully compliant with AEC-Q200 standards, this capacitor offers exceptional reliability and performance in the harsh and demanding conditions typical of automotive electronics, including extreme temperatures, vibrations, and humidity.
