Its primary function is to store and release electrical energy, filter noise, and stabilize voltage in various electronic circuits. TDK’s commitment to quality ensures that this component provides excellent performance and durability, even in demanding operational environments.

Key Specifications

• Apps. (Commercial Grade): This designation indicates that the capacitor is suitable for a wide range of general electronic applications, including consumer electronics, industrial equipment, and telecommunications, where standard reliability and performance are required. It is not specifically designed for automotive or medical life-support applications, but offers robust performance for its intended commercial use.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Specifying TDK ensures a product from a trusted manufacturer with a strong reputation for innovation and reliability in the electronics industry.
• Feature (150°CSoft): The “150°CSoft” feature highlights the capacitor’s ability to operate reliably at elevated temperatures up to 150°C. This is crucial for applications exposed to high thermal stress, providing enhanced stability and longevity compared to standard capacitors with lower maximum operating temperatures. The “Soft” aspect might imply a specific internal construction or termination designed to mitigate thermal stress.
• Tolerance (±10%): This attribute specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance means the 150nF capacitor will have an actual capacitance between 135nF and 165nF. This level of precision is common for many commercial applications where exact capacitance is important but not ultra-critical.
• L x W Size (2.0mm x 1.25mm [EIA 0805]): This refers to the physical dimensions of the capacitor. The 2.0mm length and 1.25mm width correspond to the industry-standard EIA 0805 package size. This compact form factor is ideal for space-constrained PCB designs, enabling miniaturization of electronic devices while maintaining electrical performance.
• Capacitance (150nF): The nominal capacitance value of 150 nanofarads (0.15 microfarads) indicates the amount of electrical charge the capacitor can store. This value is suitable for various filtering, coupling, and decoupling applications in digital and analog circuits.
• T(Max.) / mm (1): This likely refers to the maximum thickness of the component, which is 1mm. This dimension is important for mechanical design and ensuring proper fit within enclosures or under other components on a PCB.
• Temp. Chara. (X8R): X8R is a specific dielectric material classification according to EIA standards. It denotes a ceramic capacitor that can operate over a wide temperature range of -55°C to +150°C with a maximum capacitance change of ±15% over this range. This makes the C2012X8R1E154K085AE highly stable across significant temperature variations.
• Component Type (Ceramic Capacitor (MLCC)): This clarifies that the component is a Multilayer Ceramic Capacitor. MLCCs are known for their small size, low equivalent series resistance (ESR), and excellent frequency response, making them suitable for high-frequency applications and general-purpose filtering.
• Product Status (Production): “Production” status confirms that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply and support for new and existing designs.
• Rated Voltage [DC] / V (25): The rated voltage of 25V DC specifies the maximum continuous DC voltage that can be applied across the capacitor without causing damage or degradation. 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 premature failure.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range, directly correlating with the X8R dielectric characteristic. A ±15% change is considered stable for many commercial applications, especially those operating at elevated temperatures.
• Operating Temp. Range / °C (-55 to 150): This defines the full range of ambient temperatures within which the capacitor is designed to operate reliably. The broad range from -55°C to +150°C makes this capacitor suitable for harsh environments, including automotive under-the-hood applications (though it’s commercial grade) and industrial controls where extreme temperatures are common.

Features and Benefits

• High Temperature Stability: The X8R dielectric and 150°CSoft feature allow for stable operation across an extended temperature range of -55°C to +150°C, minimizing capacitance variation and ensuring reliable performance in thermally challenging environments.
