Key Specifications

• Applications: Automotive Grade – This designation signifies that the capacitor is specifically engineered and tested to meet the stringent requirements for use in automotive systems, ensuring reliability and performance under harsh conditions.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company, recognized globally for its high-quality and innovative electronic components, providing assurance of product excellence.
• Feature: AEC-Q200 Soft Termination – The “Soft Termination” feature indicates the capacitor incorporates a flexible conductive layer between the ceramic body and the external electrodes. This design significantly enhances the component’s resistance to thermal and mechanical stresses, preventing cracking and improving overall reliability, especially critical in automotive environments.
• AEC-Q200: YES – This confirms that the capacitor is qualified to the Automotive Electronics Council’s AEC-Q200 standard, which specifies the stress test qualification for passive components used in automotive applications. This certification is a benchmark for reliability in the automotive industry.
• Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose applications, indicating a good balance between precision and cost-effectiveness.
• L x W Size: 1.6mm x 0.8mm [EIA 0603] – This refers to the physical dimensions of the surface-mount component. The EIA 0603 standard size (0.063 inches by 0.031 inches) is a very common and compact footprint, enabling high-density PCB designs.
• Capacitance: 1μF – This is the electrical charge storage capacity of the capacitor. A 1 microfarad (μF) capacitance is suitable for a wide range of applications, including decoupling, filtering, and energy storage in power supply circuits.
• T(Max.) / mm: 0.95 – This indicates the maximum thickness of the component, which is 0.95 millimeters. This dimension is crucial for mechanical design and ensuring proper clearance in compact assemblies.
• Temperature Characteristic: X7R – X7R is a common dielectric material for ceramic capacitors. It is known for its relatively stable capacitance over a wide temperature range, typically ±15% change from -55°C to +125°C, making it suitable for many industrial and automotive applications where temperature stability is important.
• Component Type: Ceramic Capacitor (MLCC) – MLCC stands for Multi-Layer Ceramic Capacitor, which means it consists of multiple layers of ceramic dielectric and metal electrodes, allowing for high capacitance values in a small package.
• Product Status: Production – This indicates that the component is actively being manufactured and is available for mass production, ensuring long-term supply and support.
• Rated Voltage [DC] / V: 35 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 35V rating provides sufficient headroom for many 12V and 24V automotive systems.
• Cap. Change or Temp. Coef.: ±15% – This reiterates the capacitance change over the specified operating temperature range for the X7R dielectric, confirming its stability.
• Operating Temp. Range / °C: -55 to 125 – This specifies the ambient temperature range within which the capacitor is designed to operate reliably, covering extreme cold to high heat conditions commonly encountered in automotive environments.
