This passive component is designed for commercial-grade applications, offering a capacitance of 4.7µF and a rated voltage of 25V. MLCCs like this are fundamental in modern electronics, serving to store and release electrical energy, filter noise, and stabilize voltage in a wide array of circuits. TDK’s commitment to quality ensures that this capacitor provides reliable performance even in demanding environments, making it a cornerstone for various electronic designs.

Key Specifications

• Apps. (Commercial Grade): This designation indicates that the C3216X8R1E475K160AE is suitable for a broad range of general electronic devices and systems where standard reliability and performance are required. It is not specifically designed for automotive or medical life-support applications, but excels in typical consumer, industrial, and telecommunications equipment.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components. Specifying TDK as the brand assures engineers of the component’s origin from a trusted manufacturer with a long-standing reputation for innovation and reliability in passive components.
• Feature (150°CSoft): This unique feature highlights the capacitor’s ability to operate reliably at elevated temperatures up to 150°C. The “Soft” aspect often refers to specific internal construction or dielectric materials that provide enhanced thermal stability and mechanical robustness, crucial for applications exposed to high heat.
• Tolerance (±10%): The capacitance tolerance specifies the permissible deviation from the nominal capacitance value. A ±10% tolerance for a 4.7µF capacitor means its actual capacitance will fall between 4.23µF and 5.17µF. This level of precision is common for many commercial applications where exact capacitance is important but not ultra-critical.
• 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 x 1.6mm footprint corresponds to the industry-standard EIA 1206 package size, making it compatible with automated pick-and-place assembly processes and widely used PCB layouts. Its compact size allows for high-density circuit designs.
• Capacitance (4.7µF): This is the primary electrical property of the capacitor, indicating its ability to store an electrical charge. A 4.7 microfarad capacitance is a relatively high value for an MLCC of this size, making it suitable for filtering, coupling, and decoupling applications where significant charge storage or ripple current handling is needed.
• T(Max.) / mm (1.9): This attribute specifies the maximum thickness of the component, which is 1.9mm. This dimension is critical for mechanical design, ensuring proper clearance in compact enclosures and preventing interference with other components on the PCB.
• Temp. Chara. (X8R): X8R is a dielectric material classification according to EIA standards. X8R capacitors are designed for operation from -55°C to +150°C and exhibit a maximum capacitance change of ±15% over this entire operating temperature range. This makes them highly stable across wide temperature variations, ideal for demanding thermal environments.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the device as a Multilayer Ceramic Capacitor, a type of fixed capacitor where ceramic material acts as the dielectric. MLCCs are known for their small size, high capacitance values, low equivalent series resistance (ESR), and excellent high-frequency performance.
• Product Status (Production): This indicates that the C3216X8R1E475K160AE is an active, currently manufactured part, ensuring long-term availability and support from TDK. This is crucial for new designs and ongoing production runs, avoiding obsolescence issues.
• Rated Voltage [DC] / V (25): The rated voltage of 25V DC is the maximum continuous DC voltage that can be applied across the capacitor without risking dielectric breakdown or premature failure. Designing circuits with a sufficient voltage margin below this rating is essential for reliable operation.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range for the X8R dielectric, confirming that the capacitance will not deviate by more than ±15% from its nominal value between -55°C and 150°C. This stability is a key advantage of X8R ceramics.
• Operating Temp. Range / °C (-55 to 150): This specifies the full temperature range over which the capacitor is designed to operate reliably and meet its electrical specifications. The wide range from -55°C to 150°C makes it suitable for harsh industrial, outdoor, and automotive (non-safety critical) environments.

Features and Benefits

• High Temperature Performance: With an operating temperature range of -55°C to 150°C and a special “150°CSoft” feature, this capacitor is engineered for robust performance in high-heat environments, reducing the risk of thermal degradation and ensuring long-term reliability.
• Stable Capacitance (X8R Dielectric): The X8R temperature characteristic ensures a highly stable capacitance value with only a ±15% change across its wide operating temperature range, critical for applications requiring consistent circuit performance under varying thermal conditions.
• Compact EIA 1206 Package: The industry-standard 3.2mm x 1.6mm (EIA 1206) footprint allows for efficient use of PCB space, enabling miniaturization of electronic devices and compatibility with standard automated assembly processes, leading to cost-effective manufacturing.
• Versatile Commercial Grade: Designed for commercial applications, this MLCC offers a balance of performance, reliability, and cost-effectiveness, making it suitable for a vast array of general-purpose electronic circuits.
