C2012X8L1E155K125AB: High-Reliability TDK Ceramic Capacitor for Demanding Applications

C2012X8L1E155K125AB is a high-performance Multilayer Ceramic Capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is designed for commercial-grade applications requiring stable capacitance and robust operation across a wide temperature range. As a ceramic capacitor, it stores and releases electrical energy, filters noise, and stabilizes voltage in electronic circuits. Its compact 0805 form factor and advanced X8L dielectric make it particularly suitable for modern, space-constrained designs that operate under elevated thermal conditions, ensuring reliable performance in critical systems.

Key Specifications

• Applications: Commercial Grade
  This designation indicates that the capacitor is engineered for use in a broad spectrum of commercial electronic products, where reliability and consistent performance are paramount, but the extreme conditions of automotive or military applications are not typically encountered.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and advanced electronic materials. Their brand signifies a commitment to innovation, precision engineering, and manufacturing excellence, ensuring the reliability of this MLCC.
• Feature: 150°C
  This critical feature highlights the capacitor’s ability to operate continuously at temperatures up to 150°C. This extended temperature capability is vital for applications in power supplies, LED lighting, industrial control, and automotive systems where ambient or internal temperatures can be significantly elevated.
• Tolerance: ±10%
  The capacitance tolerance of ±10% means that the actual capacitance value will be within 10% of the nominal 1.5μF. This level of precision is acceptable for many filtering, coupling, and bypass applications where exact capacitance is not as critical as stability and reliability.
• L x W Size: 2.0mm x 1.25mm [EIA 0805]
  This specifies the physical dimensions of the capacitor, corresponding to the industry-standard 0805 (EIA) package size. This compact footprint is highly desirable for miniaturized electronic devices, allowing for higher component density on printed circuit boards and contributing to smaller, lighter end products.
• Capacitance: 1.5μF
  With a nominal capacitance of 1.5 microfarads, this MLCC is suitable for a variety of applications, including decoupling power lines, filtering low-frequency noise, and energy storage in power management circuits. This value offers a good balance between physical size and charge storage capability.
• Thickness (Max.): 1.45mm
  The maximum thickness of 1.45mm is an important mechanical specification, particularly for designs with strict height constraints. It ensures compatibility with various PCB assembly processes and enclosure designs, preventing interference with other components or the product casing.
• Temperature Characteristic: X8L
  The X8L dielectric material is a high-temperature ceramic formulation that allows for stable capacitance performance over a wide operating temperature range. Specifically, X8L capacitors exhibit a capacitance change of +15% to -40% over the temperature range of -55°C to +150°C, which is a significant improvement over standard X7R or X5R dielectrics for high-temperature environments.
• Component Type: Ceramic Capacitor (MLCC)
  As a Multilayer Ceramic Capacitor, it is constructed from multiple alternating layers of ceramic dielectric and metal electrodes. This construction provides high volumetric efficiency, low equivalent series resistance (ESR), and excellent high-frequency performance, making it a versatile choice for modern electronics.
• Product Status: Production
  This indicates that the C2012X8L1E155K125AB is an active, currently manufactured part, ensuring long-term availability and support for new and existing designs. This is crucial for industrial and commercial products with extended lifecycles.
• Rated Voltage [DC]: 25V
  The capacitor is rated for a maximum DC voltage of 25 volts. This voltage rating is suitable for many low-voltage digital and analog circuits, including those powered by 3.3V, 5V, 12V, or 24V supplies, providing a sufficient safety margin for typical operating conditions.
• Capacitance Change or Temperature Coefficient: +15%, -40%
  This value precisely defines the capacitance variation over the specified operating temperature range (-55°C to 150°C) for the X8L dielectric. It means the capacitance will not increase by more than 15% and will not decrease by more than 40% from its nominal value at 25°C, providing predictable performance in thermally challenging environments.
• Operating Temperature Range: -55°C to 150°C
  This extremely broad operating temperature range is a key advantage of this MLCC. It allows the component to function reliably in harsh environments, from extreme cold to very high heat, making it ideal for robust industrial, automotive, and outdoor applications where temperature stability is critical.
