CGA5F2X8R2A333M085AD

Overview

CGA5F2X8R2A333M085AD is a high-performance ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This specific model is designed for demanding automotive applications, offering exceptional reliability and stability under harsh 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 their reliability and performance 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 and materials. Their brand reputation ensures that this ceramic capacitor benefits from advanced manufacturing processes, stringent quality control, and innovative material science, resulting in a reliable and high-performing product.

Feature: AEC-Q200 Mid 150°C Glue
This feature highlights two critical aspects. Firstly, AEC-Q200 certification confirms its suitability for automotive applications. Secondly, the “Mid 150°C Glue” indicates that the component utilizes a specialized adhesive capable of maintaining its integrity and performance even when exposed to temperatures up to 150°C. This is crucial for long-term reliability in high-temperature automotive environments.

AEC-Q200: YES
This explicit confirmation of AEC-Q200 compliance is a vital assurance for designers and engineers in the automotive sector. AEC-Q200 is a global standard for stress test qualification for passive components used in automotive applications, ensuring that the component can withstand the harsh conditions of vehicle operation.

Tolerance: ±20%
The capacitance tolerance specifies the permissible deviation from the nominal capacitance value. A ±20% tolerance means the actual capacitance will fall within 20% above or below the stated 33nF. This level of tolerance is common for general-purpose decoupling and filtering applications where precise capacitance is not the most critical factor, but cost-effectiveness and robustness are prioritized.

L x W Size: 3.2mm x 1.6mm [EIA 1206]
This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The 3.2mm length and 1.6mm width correspond to the industry-standard EIA 1206 package size. This size is widely adopted, offering a balance between component miniaturization and ease of handling during automated assembly processes, making it suitable for a broad range of PCB designs.

Capacitance: 33nF
This is the nominal electrical capacitance of the component, measured in nanofarads (nF). A capacitance of 33nF is suitable for various applications, including signal coupling, decoupling, and filtering in medium-frequency circuits, helping to smooth out voltage fluctuations and improve signal integrity.

T(Max.) / mm: 1
This indicates the maximum thickness of the capacitor, which is 1 millimeter. This dimension is important for mechanical design considerations, especially in applications where space is constrained or specific height clearances are required on the printed circuit board.

Temp. Chara.: X8R
X8R is a specific temperature characteristic code defined by the Electronic Industries Alliance (EIA). Capacitors with X8R characteristics are designed to operate over a wide temperature range of -55°C to +150°C, with a maximum capacitance change of ±15% over this range. This makes them highly suitable for automotive and industrial applications where stable performance across varying temperatures is essential.

Component Type: Ceramic Capacitor (MLCC)
MLCC stands for Multi-Layer Ceramic Capacitor. These capacitors are constructed by stacking multiple layers of ceramic dielectric and metal electrodes, offering high capacitance values in a small form factor, excellent frequency response, and high reliability. They are widely used in modern electronics due to their versatility and performance.

Product Status: Production (NRND)
“Production (NRND)” indicates that the component is currently in active production but is classified as “Not Recommended for New Designs.” While existing designs can continue to use this part, engineers are advised to consider newer alternatives for future projects, potentially due to the introduction of improved versions or a shift in manufacturing focus.

Rated Voltage [DC] / V: 100
This specifies the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 100V rating provides a substantial safety margin for many automotive and industrial 12V or 24V systems, ensuring robust operation and reliability.

Cap.Change or Temp.Coef.: ±15%
This attribute directly relates to the X8R temperature characteristic, confirming that the capacitance will not deviate by more than ±15% from its nominal value across the specified operating temperature range. This stability is critical for maintaining circuit performance under varying thermal conditions.

Operating Temp. Range / °C: -55 to 150
This defines the full temperature spectrum over which the capacitor is guaranteed to operate within its specified parameters. The exceptionally wide range of -55°C to +150°C underscores its suitability for extremely demanding environments, such as under-the-hood automotive applications or industrial machinery exposed to wide temperature swings.
