Key Specifications

Applications (Apps.): Commercial Grade
This designation indicates that the capacitor is engineered for use in a wide array of general electronic devices and systems, where standard reliability and performance are required. It is suitable for non-critical applications that do not demand the extreme robustness of automotive or military-grade components, yet still offers excellent performance for everyday commercial products.

Brand: TDK
As a product of TDK, this capacitor benefits from decades of innovation and manufacturing excellence. TDK is renowned for producing high-quality, reliable electronic components, ensuring that this MLCC meets stringent industry standards and offers consistent performance.

Feature: MidMega
The “MidMega” feature likely refers to TDK’s proprietary technology or series classification for capacitors that offer a balance of high capacitance in a relatively compact size, suitable for applications requiring significant energy storage without excessive board space. This is crucial for miniaturization trends in modern electronics.

Tolerance: ±10%
This specification indicates the permissible deviation of the actual capacitance value from its nominal value (1μF). A ±10% tolerance is common for general-purpose capacitors, ensuring that the component performs within acceptable parameters for most commercial applications without requiring overly precise (and often more expensive) components.

L x W Size: 5.7mm x 5.0mm [EIA 2220]
This refers to the physical dimensions of the capacitor. The 5.7mm length and 5.0mm width correspond to the EIA 2220 standard package size. This large footprint allows for higher capacitance and voltage ratings compared to smaller packages, making it suitable for power supply sections or filtering applications where significant energy storage is needed.

Capacitance: 1μF
This is the fundamental electrical property of the capacitor, representing its ability to store charge. A 1 microfarad (μF) capacitance is substantial for an MLCC, making it effective for decoupling, filtering, and energy storage in power circuits, where larger capacitance values are often required to smooth out voltage fluctuations.

T(Max.) / mm: 3.5
This denotes the maximum thickness of the component, which is 3.5 millimeters. This dimension is critical for mechanical design and PCB layout, ensuring that the capacitor fits within the vertical clearance constraints of the electronic assembly.

Temp. Chara.: X7T
Temperature characteristics describe how the capacitance changes over a specified temperature range. X7T indicates that the capacitance change is within +22% to -33% over an operating temperature range of -55°C to +125°C. This characteristic is vital for applications where stable performance is required across varying environmental temperatures.

Component Type: Ceramic Capacitor (MLCC)
This identifies the fundamental type of capacitor. MLCCs are known for their small size, high frequency performance, and excellent reliability, making them ubiquitous in modern electronics for a wide range of filtering, decoupling, and timing applications.

Product Status: Production
“Production” status confirms that the component is actively being manufactured and is readily available for purchase and integration into new designs or existing production lines, ensuring long-term supply and support.

Rated Voltage [DC] / V: 450
This is the maximum continuous DC voltage that can be applied across the capacitor without causing damage. A 450V rating is quite high for an MLCC, making this component suitable for applications involving higher voltage rails, such as power supplies, LED drivers, and industrial control systems, providing a significant safety margin.

Cap.Change or Temp.Coef.: +22,-33%
This reiterates the capacitance change over the operating temperature range, specifically from -55°C to 125°C. Understanding this variation is crucial for designers to ensure circuit stability and performance across the expected thermal conditions.

Operating Temp. Range / °C: -55 to 125
This specifies the full range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified electrical characteristics. A wide range from -55°C to 125°C highlights its suitability for harsh industrial or outdoor environments.
