Key Specifications

The C3216X5R1E476M160AC boasts several key specifications that define its performance and suitability for various applications:

• Apps.: Commercial Grade – This designation indicates that the capacitor is designed and tested to meet the rigorous demands of commercial electronic products, ensuring stable operation and longevity in typical business and consumer environments.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, particularly passive components like capacitors, inductors, and ferrites. Choosing TDK ensures a product backed by extensive research, development, and manufacturing expertise.
• Tolerance: ±20% – This specifies the permissible deviation of the actual capacitance value from its nominal value (47μF). A ±20% tolerance is common for general-purpose capacitors and is acceptable in many non-precision filtering and coupling applications.
• L x W Size: 3.2mm x 1.6mm [EIA 1206] – This refers to the physical dimensions of the capacitor. The 3.2mm length and 1.6mm width correspond to the industry-standard EIA 1206 package size, making it compatible with automated pick-and-place assembly processes and suitable for designs where space is a consideration.
• Capacitance: 47μF – This is the primary electrical property of the capacitor, indicating its ability to store charge. A 47 microfarad capacitance is a relatively high value for an MLCC of this size, making it effective for bulk decoupling, power supply filtering, and energy storage in various circuits.
• T(Max.) / mm: 1.8 – This specifies the maximum thickness of the component, which is important for board layout and ensuring proper clearance in compact designs.
• Temp. Chara.: X5R – X5R is a common dielectric material characteristic for ceramic capacitors. It indicates that the capacitance change over the operating temperature range (-55°C to 85°C) will not exceed ±15%, making it suitable for general-purpose applications where moderate temperature stability is required.
• Rated Voltage [DC] / V: 25 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. For the C3216X5R1E476M160AC, a 25V rating allows its use in a wide array of low to medium voltage circuits, including many microcontroller and power management applications.
• Operating Temp. Range / °C: -55 to 85 – This defines the temperature limits within which the capacitor is designed to operate reliably and maintain its specified electrical characteristics. This broad range makes it suitable for diverse environmental conditions encountered in commercial electronics.

Features and Benefits

• High Capacitance in Compact Size: The 47μF capacitance in an EIA 1206 package offers significant energy storage and filtering capabilities in a small footprint, optimizing PCB space and enabling miniaturization of electronic devices.
• Reliable X5R Dielectric: The X5R temperature characteristic ensures stable performance across a wide operating temperature range (-55°C to 85°C) with a predictable ±15% capacitance change, making it a dependable choice for general-purpose applications.
• Commercial Grade Quality: Designed for commercial applications, this capacitor meets stringent quality and reliability standards, ensuring robust performance and longevity in consumer electronics, industrial controls, and communication equipment.
• TDK Manufacturing Excellence: As a product from TDK, users benefit from decades of expertise in passive component manufacturing, guaranteeing consistent quality, advanced materials, and precise electrical characteristics.
• Versatile Voltage Rating: With a 25V DC rated voltage, it is suitable for a broad spectrum of low-voltage digital and analog circuits, providing flexibility for various design requirements.

Typical Applications

• Power Supply Decoupling: The 47μF capacitance is ideal for decoupling power rails in digital circuits, filtering out high-frequency noise and providing local energy storage to stabilize voltage levels for ICs and microcontrollers, thereby improving system stability and reducing electromagnetic interference (EMI).
• Filtering in DC-DC Converters: In switch-mode power supplies and DC-DC converters, this capacitor can be used for input and output filtering, smoothing ripple voltage, and ensuring a clean power supply to sensitive loads. Its compact size is advantageous in space-constrained power modules.
• Signal Coupling and Bypass: While primarily for power applications due to its high capacitance, it can also serve in non-critical signal coupling or bypass applications where AC signals need to pass while DC is blocked, or unwanted AC components need to be shunted to ground.
• General-Purpose Timing Circuits: In certain timing or oscillator circuits where a stable capacitance value is required within the X5R temperature limits, this capacitor can contribute to reliable timing functions.
• Automotive Infotainment and Telematics: Although commercial grade, its robust construction and wide operating temperature range make it suitable for non-safety-critical automotive applications such as infotainment systems, GPS modules, and telematics units where environmental conditions can vary.
