CGA4J2X7R2A473M125AA is a high-performance multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This specific component is designed for demanding automotive applications, offering exceptional reliability and stability under harsh operating conditions. As a passive component, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in various electronic circuits. Its robust construction and adherence to stringent automotive standards make it an ideal choice for critical systems where performance and longevity are paramount.

Key Specifications

Applications: Automotive Grade
This designation signifies that the capacitor is specifically engineered and tested to meet the rigorous demands of automotive electronics. Components with this rating are subjected to extensive qualification processes to ensure reliable operation in environments characterized by extreme temperatures, vibrations, and electrical transients, which are common in vehicles.

Brand: TDK
TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand signifies a commitment to innovation, reliability, and precision engineering, making them a trusted supplier in the global electronics industry.

Feature: AEC-Q200Mid & 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, while “AEC-Q200Mid” suggests it meets a specific level or subset of these qualifications, ensuring its suitability for mid-level criticality automotive systems. This qualification is crucial for ensuring the component’s durability and performance in vehicle environments.

Tolerance: ±20%
This specification indicates the permissible deviation of the actual capacitance value from its nominal value (47nF). A ±20% tolerance is common for general-purpose ceramic capacitors, providing sufficient accuracy for many filtering, coupling, and bypass applications where precise capacitance is not the most critical factor.

L x W Size: 2.0mm x 1.25mm [EIA 0805]
This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The 2.0mm x 1.25mm size corresponds to the industry-standard EIA 0805 package code, which is widely adopted for its balance of compact footprint and ease of handling during automated assembly processes. This small size allows for high-density circuit board designs.

Capacitance: 47nF
The nominal capacitance value of 47 nanofarads (nF) is a common value used in a wide array of electronic circuits for various functions, including signal coupling, decoupling, filtering, and timing. This value provides a good balance for many general-purpose applications in automotive and industrial electronics.

T(Max.) / mm: 1.45
This indicates the maximum thickness of the component, which is 1.45 millimeters. This dimension is important for mechanical design considerations, ensuring the component fits within specific height constraints on a printed circuit board, especially in compact or low-profile applications.

Temperature Characteristics: X7R
X7R is a common dielectric material classification for ceramic capacitors, known for its stable performance over a broad temperature range. Capacitors with X7R dielectric exhibit a capacitance change of no more than ±15% over an operating temperature range of -55°C to +125°C, making them suitable for applications requiring stable capacitance in varying thermal conditions.

Component Type: Ceramic Capacitor (MLCC)
This identifies the fundamental type of component. MLCCs are highly versatile and widely used due to their compact size, high capacitance values for their volume, excellent frequency response, and reliability. They consist of multiple layers of ceramic dielectric and metal electrodes stacked alternately.

Product Status: Production
“Production” status indicates that the component is actively being manufactured and is readily available for purchase. This assures buyers of ongoing supply and support for new designs and existing production runs, without concerns about obsolescence in the near future.

Rated Voltage [DC] / V: 100
This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 100V rating provides a substantial margin for many automotive and industrial applications, where voltage spikes or transients might occur, ensuring robust operation.

Cap. Change or Temp. Coef.: ±15%
This reiterates the capacitance change over the specified operating temperature range, directly linked to the X7R dielectric characteristics. It means the capacitance value will not deviate more than ±15% from its nominal value when operating between -55°C and +125°C, ensuring predictable circuit behavior.

Operating Temp. Range / °C: -55 to 125
This wide operating temperature range signifies the capacitor’s ability to function reliably in extreme thermal conditions, from very cold to very hot environments. This is a critical parameter for automotive components, which must perform consistently across diverse climates and engine bay temperatures.
