Key Specifications

• Applications: Commercial Grade
  This capacitor is engineered for commercial applications, indicating its suitability for a broad spectrum of general electronic devices where robust performance and cost-effectiveness are crucial. It meets the reliability standards expected in everyday consumer electronics, industrial controls, and communication equipment.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components. Choosing a TDK component ensures you are integrating a product from a manufacturer with a long-standing reputation for innovation, reliability, and stringent quality control in passive components.
• Feature: Mid150°C
  The “Mid150°C” feature highlights the capacitor’s capability to operate effectively at elevated temperatures, specifically up to 150°C. This is a critical attribute for applications in harsh thermal environments, such as automotive electronics, power supplies, or industrial machinery where standard components might fail.
• Tolerance: ±10%
  A capacitance tolerance of ±10% indicates the permissible deviation from the nominal capacitance value. For the C2012X8R2A223K125AA, this means the actual capacitance will be within 10% of 22nF. This level of tolerance is common for general-purpose applications where precise capacitance is not overly critical but stability is still required.
• L x W Size: 2.0mm x 1.25mm [EIA 0805]
  This specifies the physical dimensions of the capacitor. With a length of 2.0mm and a width of 1.25mm, it conforms to the EIA 0805 standard package size. This compact footprint is ideal for surface-mount technology (SMT) assembly, enabling miniaturization and high-density circuit board designs in modern electronic devices.
• Capacitance: 22nF
  The nominal capacitance value of 22 nanofarads (nF) defines the amount of electrical charge the capacitor can store. This specific value is suitable for various filtering, coupling, decoupling, and timing applications in electronic circuits.
• T(Max.) / mm: 1.45
  This refers to the maximum thickness of the component, which is 1.45mm. This dimension is important for mechanical design considerations, ensuring the component fits within the height constraints of the circuit board assembly and enclosure.
• Temperature Characteristic: X8R
  The X8R temperature characteristic indicates that the capacitor’s capacitance change will be within ±15% over an operating temperature range of -55°C to +150°C. This makes the C2012X8R2A223K125AA highly stable across a very broad temperature spectrum, superior to common X7R or X5R types for high-temperature applications.
• Component Type: Ceramic Capacitor (MLCC)
  As a Ceramic Capacitor (MLCC), it utilizes ceramic material as the dielectric. MLCCs are known for their small size, high reliability, low equivalent series resistance (ESR), and excellent frequency characteristics, making them ubiquitous in modern electronics.
• Product Status: Production
  “Production” status confirms that this component is actively being manufactured and is readily available for new designs and mass production, ensuring long-term supply stability.
• Rated Voltage [DC] / V: 100
  The rated voltage of 100V DC signifies the maximum continuous DC voltage that can be applied across the capacitor without causing damage. It is crucial to select a capacitor with a rated voltage significantly higher than the maximum expected operating voltage in the circuit to ensure reliability and prevent dielectric breakdown.
• Cap. Change or Temp. Coef.: ±15%
  This reiterates the capacitance change over the specified operating temperature range, which is ±15%. This parameter is directly linked to the X8R temperature characteristic and is vital for applications where capacitance stability over temperature is critical.
• Operating Temp. Range / °C: -55 to 150
  This specifies the full temperature range over which the capacitor is designed to operate reliably, from -55°C to +150°C. This wide range, especially the high upper limit, makes it suitable for demanding industrial, automotive, and high-power applications.
