CKG32KX7S1H475K335AH is a high-performance ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This specific model, part of the passive components category, is designed to store and release electrical energy, filter noise, and stabilize voltage in various electronic circuits. Its robust construction and precise electrical characteristics make it suitable for demanding commercial-grade applications, ensuring reliable operation and circuit integrity.

Key Specifications

This TDK ceramic capacitor boasts several critical attributes that define its performance and suitability for specific designs:

Applications (Commercial Grade): This designation indicates that the capacitor is designed and tested to meet the rigorous standards required for commercial electronic products. It signifies reliability and performance in a wide range of everyday electronic devices, as opposed to automotive or industrial-specific grades.

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 assures designers of adherence to strict manufacturing standards and consistent performance.

Feature (Mega): The “Mega” feature often refers to TDK’s proprietary MegaCap series, which incorporates a unique structure to enhance mechanical robustness and prevent cracking due to board flexure or thermal stress. This is particularly important in applications where physical durability is critical.

Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose capacitors, indicating a good balance between precision and cost-effectiveness for many commercial applications.

L x W Size (3.2mm x 2.5mm [EIA 1210]): This refers to the physical dimensions of the surface-mount device (SMD) capacitor. An EIA 1210 package is a relatively common size, offering a good balance between capacitance value, power handling, and board space. The dimensions are crucial for PCB layout and automated assembly processes.

Capacitance (4.7µF): This is the primary electrical characteristic, indicating the capacitor’s ability to store charge. A capacitance of 4.7 microfarads is substantial for an MLCC, making it suitable for filtering power supplies, decoupling ICs, and energy storage in various circuits.

T(Max.) / mm (3.45): This denotes the maximum thickness of the component, which is important for clearance considerations in compact designs and for automated pick-and-place machinery.

Temperature Characteristic (X7S): The X7S dielectric material is a Class II ceramic, known for its stable performance over a wide temperature range. It offers a capacitance change of ±22% over an operating temperature range of -55°C to +125°C, making it suitable for applications exposed to significant temperature variations.

Product Status (Obsolete): While this specific part is marked as obsolete, it’s important for designers to be aware of its characteristics for legacy designs or for finding suitable replacements. Obsolete status means the manufacturer no longer produces it, but stock may still be available through distributors.

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 common low-voltage and medium-voltage commercial circuits.

Cap. Change or Temp. Coef. (±22%): This reiterates the capacitance change over the specified temperature range for the X7S dielectric, confirming its stability characteristics.

Operating Temp. Range / °C (-55 to 125): This wide operating temperature range highlights the capacitor’s robustness, allowing it to function reliably in extreme cold and hot environments, which is critical for many commercial and industrial applications.
