Key Specifications

• Applications (Commercial Grade): This designation indicates that the C1005X5R1A225K050BC capacitor is engineered for use in general electronic devices and systems where standard reliability and performance are required, as opposed to specialized automotive or high-reliability military applications. It signifies suitability for a broad range of consumer, industrial, and communication electronics.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components and materials. Specifying TDK assures engineers of a product built to stringent manufacturing standards, offering reliability and consistent performance.
• Feature (General): This attribute confirms the capacitor’s suitability for general-purpose applications, implying it is not optimized for highly specialized functions like high-frequency RF or ultra-low ESR, but rather provides balanced performance for common circuit requirements.
• Tolerance (±10%): The capacitance tolerance indicates the permissible deviation from the nominal capacitance value. A ±10% tolerance means the actual capacitance of the 2.2μF capacitor will fall between 1.98μF and 2.42μF. This level of precision is acceptable for many commercial applications where exact capacitance is not critically sensitive.
• L x W Size (1.0mm x 0.5mm [EIA 0402]): This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The 0402 EIA standard size is extremely small, making it ideal for miniaturized electronic devices where board space is at a premium. Its compact footprint enables higher component density on printed circuit boards.
• Capacitance (2.2μF): This is the primary electrical property of the capacitor, representing its ability to store charge. A 2.2 microfarad capacitance is a relatively high value for an MLCC of this size, making it effective for decoupling power rails, filtering low-frequency noise, and energy storage in compact designs.
• T(Max.) / mm (0.55): This denotes the maximum thickness of the component, which is 0.55mm. This dimension is critical for mechanical design, especially in thin electronic products where vertical clearance is limited.
• Temperature Characteristic (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% from its nominal value at 25°C. This makes X5R capacitors suitable for applications requiring stable performance over a moderate temperature range.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the product as a Multi-Layer Ceramic Capacitor, highlighting its construction from multiple layers of ceramic dielectric and metal electrodes, which contributes to its high capacitance density and reliability.
• Product Status (Production): This signifies 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): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 10V rating is common for low-voltage digital and analog circuits, suitable for power supply decoupling in 3.3V or 5V systems.
• Cap. Change or Temp. Coef. (±15%): This reiterates the capacitance stability over temperature, specifically for the X5R dielectric, confirming that the capacitance will vary by no more than ±15% across its full operating temperature range.
• Operating Temp. Range / °C (-55 to 85): This specifies the ambient temperature range within which the capacitor is designed to operate reliably and meet its electrical specifications. The wide range from -55°C to +85°C makes it suitable for many industrial and consumer environments.

Features and Benefits

• High Capacitance in a Small Footprint: The C1005X5R1A225K050BC offers a significant 2.2μF capacitance in an ultra-compact 0402 (1.0mm x 0.5mm) package, enabling miniaturization and higher component density in modern electronic devices.
• Reliable TDK Quality: Manufactured by TDK, a leader in passive components, this MLCC guarantees high quality, consistent performance, and long-term reliability, reducing the risk of field failures.
• Stable Performance with X5R Dielectric: The X5R temperature characteristic ensures that the capacitance remains stable within ±15% over a broad operating temperature range of -55°C to +85°C, making it suitable for applications requiring consistent electrical behavior across varying environmental conditions.
• Versatile Commercial Grade Component: Designed for commercial applications, this capacitor is a cost-effective yet reliable solution for general-purpose filtering, bypassing, and coupling tasks in a wide array of electronic products.
• Low ESR and ESL Characteristics: As an MLCC, it inherently possesses low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), which are crucial for effective high-frequency decoupling and filtering, ensuring clean power delivery to sensitive ICs.

Typical Applications

• Power Supply Decoupling: The C1005X5R1A225K050BC is frequently used to decouple power supply lines for integrated circuits (ICs). Its 2.2μF capacitance effectively filters out high-frequency noise and transient voltage spikes, providing a stable power source for digital and analog circuits, thereby improving system performance and reliability.
• Signal Filtering: In various signal processing circuits, this capacitor can be employed in low-pass, high-pass, or band-pass filter configurations. Its stable capacitance and compact size make it ideal for filtering unwanted frequencies from audio, data, or control signals, ensuring signal integrity.
• Bypassing Applications: It serves as an excellent bypass capacitor, shunting AC components of a signal to ground while allowing DC to pass. This is crucial in preventing noise from propagating through power lines and affecting the operation of sensitive components, particularly in microcontrollers and DSPs.
• Timing Circuits: While not a precision timing component, the C1005X5R1A225K050BC can be utilized in less critical RC timing circuits, such as simple oscillators or delay lines, where its capacitance value and tolerance are sufficient for the application’s requirements.
• General Purpose Energy Storage: In compact portable devices or battery-powered applications, this capacitor can provide local energy storage, helping to smooth out current demands and supply instantaneous power bursts when required, thus enhancing the overall stability of the power delivery system.
