Key Specifications

The attributes of the C3225X7S1A476M250AC are crucial for understanding its performance and suitability for specific applications:

• Apps. (Commercial Grade): This designation indicates the capacitor is suitable for a wide range of general electronic devices and systems where standard reliability and performance are required, distinct from automotive or medical grades that have stricter requirements.
• Brand (TDK): TDK is a renowned Japanese electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites, ensuring a reliable and well-engineered product.
• Feature (General): This signifies that the capacitor is a standard, versatile component without specialized characteristics like low ESR or high ripple current, making it suitable for a broad array of common circuit functions.
• Tolerance (±20%): The capacitance value of 47μF can vary by up to ±20% from its nominal value. This tolerance is common for ceramic capacitors of this type and is acceptable in many non-precision filtering and bypass applications.
• L x W Size (3.2mm x 2.5mm [EIA 1210]): This refers to the physical dimensions of the capacitor, with a length of 3.2mm and a width of 2.5mm. The EIA 1210 code is an industry standard for surface-mount components, indicating a relatively larger package size suitable for higher capacitance values and easier handling during assembly.
• Capacitance (47μF): This is the primary electrical property, indicating its ability to store 47 microfarads of charge. This relatively high capacitance for an MLCC makes it suitable for power supply filtering, decoupling, and energy storage.
• T(Max.) / mm (2.8): This specifies the maximum thickness of the component as 2.8mm. This dimension is important for PCB layout and ensuring proper clearance in compact designs.
• Temp. Chara. (X7S): The X7S dielectric material defines the capacitor’s performance over temperature. It guarantees a capacitance change of no more than ±22% over an operating temperature range of -55°C to +125°C, making it suitable for applications requiring stable performance across a wide thermal spectrum.
• Component Type (Ceramic Capacitor (MLCC)): This identifies it as a Multilayer Ceramic Capacitor, known for its high volumetric efficiency, low ESR, and excellent high-frequency characteristics.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply for new and existing designs.
• Rated Voltage [DC] / V (10): The capacitor is designed to operate reliably with a maximum DC voltage of 10 volts. Exceeding this voltage can lead to component failure.
• Cap.Change or Temp.Coef. (±22%): This reiterates the capacitance variation over the specified temperature range, directly correlating with the X7S temperature characteristic.
• Operating Temp. Range / °C (-55 to 125): This specifies the full temperature range within which the capacitor is guaranteed to operate within its stated specifications, highlighting its robustness for diverse environmental conditions.

Features and Benefits

• High Capacitance in a Compact Size: The 47μF capacitance in an EIA 1210 package offers excellent volumetric efficiency, enabling designers to achieve significant energy storage and filtering in space-constrained applications.

• Robust Commercial Grade Reliability: Designed for commercial applications, the C3225X7S1A476M250AC provides consistent and dependable operation, reducing the risk of field failures in general electronic devices.
• Low Equivalent Series Resistance (ESR): As an MLCC, it inherently offers low ESR, which is critical for efficient power supply decoupling and filtering, minimizing power loss and improving circuit performance.
• Manufactured by TDK: Leveraging TDK’s extensive expertise and stringent quality control, users benefit from a high-quality, reliable component from a trusted industry leader.

Typical Applications

The C3225X7S1A476M250AC is a versatile component suitable for a broad array of electronic applications:

• Power Supply Decoupling: Its high capacitance and low ESR make it ideal for decoupling ICs from power supply rails, suppressing voltage fluctuations and noise to ensure stable operation of digital and analog circuits. For instance, it can be used on the input or output of voltage regulators to smooth out ripples.
• General Purpose Filtering: This capacitor can effectively filter unwanted high-frequency noise in various signal paths, improving signal integrity in communication systems, audio circuits, and sensor interfaces. It’s often employed in RC filters or as part of LC filters.
• Energy Storage and Buffering: In applications requiring temporary energy storage, such as in switch-mode power supplies (SMPS) or LED drivers, the 47μF capacitance can provide charge buffering to handle transient current demands or maintain output voltage during brief power interruptions.
• Timing Circuits: While not a precision timing component, its stable capacitance can be utilized in non-critical timing applications, such as simple RC oscillators or delay circuits, where the ±20% tolerance is acceptable.
• Bypass Capacitors: Placed across power and ground pins of active components, it bypasses high-frequency noise directly to ground, preventing it from propagating through the power distribution network and interfering with other components. This is crucial in microcontrollers and DSPs.

In summary, the C3225X7S1A476M250AC from TDK is a reliable and high-performance multilayer ceramic capacitor, offering a robust solution for a wide range of commercial electronic designs. Its excellent electrical characteristics and TDK’s manufacturing quality ensure stable operation across diverse environmental conditions.
