C2012X5R1E226M125AC C2012X5R1E226M125AC Ceramic Capacitor (MLCC)

C2012X5R1E226M125AC is a high-performance Multilayer Ceramic Capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is designed for a wide range of commercial-grade applications, providing essential capacitance in electronic circuits. As a ceramic capacitor, it stores and releases electrical energy, filters noise, and stabilizes voltage, playing a critical role in the reliable operation of modern electronic devices. Its compact size and robust electrical characteristics make it an ideal choice for space-constrained and demanding environments.

Key Specifications

The Capacitance of 22μF (microfarads) indicates the component’s ability to store electrical charge. This value is substantial for an MLCC of its size, making it suitable for power supply decoupling, energy storage, and low-frequency filtering applications where significant charge accumulation is required. The Rated Voltage [DC] / V of 25V specifies the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. This rating ensures compatibility with common low-voltage power rails found in many commercial electronic systems. The Tolerance of ±20% defines the permissible variation from the nominal capacitance value, which is typical for X5R dielectric materials and acceptable for many non-precision applications like power filtering. The L x W Size of 2.0mm x 1.25mm, corresponding to the EIA 0805 standard, denotes its physical dimensions. This widely adopted surface-mount package size allows for automated assembly and integration into compact PCB layouts. The Temp. Chara. (Temperature Characteristic) is X5R, which signifies a dielectric material that offers a relatively stable capacitance over a broad temperature range. This is further detailed by the Cap.Change or Temp.Coef. of ±15% over the full Operating Temp. Range / °C of -55 to 85°C, making it suitable for environments with moderate temperature fluctuations. The T(Max.) / mm of 1.45mm specifies the maximum thickness of the component, which is crucial for mechanical design and clearance considerations in densely packed circuits.
