Key Specifications

Applications (Commercial Grade): This specification indicates that the C2012X5R1C226M125AC capacitor is engineered and tested to meet the rigorous requirements of commercial electronic products. This means it is suitable for a broad spectrum of consumer electronics, industrial equipment, and general-purpose applications where standard reliability and performance are critical, distinguishing it from automotive or high-reliability military-grade components.

Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its expertise in magnetic materials and electronic components. Specifying TDK as the brand assures engineers of the component’s quality, adherence to international standards, and access to extensive technical support and reliability data, reflecting decades of innovation in passive component manufacturing.

Feature (General): The ‘General’ feature designation signifies that this capacitor is a versatile, standard-purpose component. It is not optimized for highly specialized functions like ultra-low ESR or high-temperature operation but rather provides a balanced set of electrical characteristics suitable for a vast majority of common circuit designs, making it a workhorse component for many applications.

Tolerance (±20%): This attribute defines the permissible deviation of the actual capacitance value from its nominal value. A ±20% tolerance for the C2012X5R1C226M125AC is typical for X5R dielectric capacitors, indicating that while it offers substantial capacitance, its exact value can vary within this range. This tolerance is acceptable for applications where precise capacitance is not critical, such as power supply decoupling or bulk energy storage.

L x W Size (2.0mm x 1.25mm [EIA 0805]): This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The 2.0mm x 1.25mm size corresponds to the industry-standard EIA 0805 package code. This compact footprint is highly desirable for modern electronic assemblies, enabling miniaturization and high-density PCB designs, which are crucial for portable devices and space-constrained applications.

Capacitance (22μF): The capacitance value of 22 microfarads (μF) is a significant rating for an MLCC of this size. This high capacitance makes it particularly effective for applications requiring substantial charge storage, such as input/output filtering in power supplies, bulk decoupling for integrated circuits, and energy reservoir functions.

T(Max.) / mm (1.45): This specifies the maximum thickness of the component, which is 1.45mm. This dimension is critical for mechanical design and PCB layout, ensuring proper clearance in stacked assemblies or enclosures. A relatively thin profile contributes to the overall slimness of electronic devices.

Temp. Chara. (X5R): X5R is a ceramic dielectric material classification defined by EIA. It indicates that the capacitance change over the operating temperature range is within ±15% from -55°C to +85°C. This characteristic makes the C2012X5R1C226M125AC suitable for a wide range of commercial and industrial environments where moderate temperature stability is required.

Component Type (Ceramic Capacitor (MLCC)): This explicitly identifies the component as a Multilayer Ceramic Capacitor. MLCCs are known for their excellent high-frequency performance, low equivalent series resistance (ESR), and high reliability, making them a cornerstone in modern electronics.

Product Status (Production): A ‘Production’ status indicates that the component is actively being manufactured and is readily available for purchase in volume. This assures designers of long-term supply and stability for new and existing designs, avoiding obsolescence issues.

Rated Voltage [DC] / V (16): The rated voltage of 16V DC signifies the maximum continuous DC voltage that can be applied across the capacitor without causing damage or significantly degrading its performance. This voltage rating is common for logic circuits, low-power microcontrollers, and various digital and analog applications.

Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified temperature range, specifically for the X5R dielectric. It means that the capacitance value will not deviate by more than ±15% from its nominal value when operated between -55°C and +85°C, ensuring predictable performance across varying thermal conditions.

Operating Temp. Range / °C (-55 to 85): This specifies the full temperature range over which the capacitor is designed to operate reliably and meet its electrical specifications. The range of -55°C to +85°C is standard for commercial-grade components, covering most indoor and many outdoor industrial environments.
