Key Specifications

The attributes of the C3216X8R1H105K160AE are carefully engineered to meet stringent performance requirements:

• Apps. (Commercial Grade): This designation indicates that the capacitor is suitable for a wide array of commercial electronic devices, where reliability and consistent performance are crucial but do not require the extreme robustness of automotive or military-grade components. It ensures a balance of cost-effectiveness and dependable operation.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components. Specifying TDK assures engineers of the component’s manufacturing excellence, adherence to international standards, and robust performance.
• Feature (150°CSoft): This unique feature highlights the capacitor’s ability to operate reliably at elevated temperatures up to 150°C. The “Soft” characteristic often refers to a design that mitigates thermal stress and mechanical cracking, enhancing the component’s longevity in high-temperature environments.
• Tolerance (±10%): The capacitance value of 1μF is guaranteed to be within ±10% of its nominal value. This tolerance is critical for circuit designers, as it ensures predictable circuit behavior and performance, especially in timing and filtering applications where precise capacitance is important.
• L x W Size (3.2mm x 1.6mm [EIA 1206]): This specifies the physical dimensions of the capacitor, corresponding to the industry-standard EIA 1206 package size. This compact footprint is ideal for space-constrained PCB designs, allowing for higher component density and miniaturization of electronic products.
• Capacitance (1μF): This is the primary electrical characteristic, indicating the component’s ability to store electrical charge. A 1μF capacitance is commonly used for decoupling power lines, filtering noise, and in resonant circuits across various digital and analog applications.
• T(Max.) / mm (1.9): This refers to the maximum thickness of the component, which is 1.9mm. This dimension is important for mechanical design considerations, particularly in applications with strict height restrictions or when designing enclosures.
• Temp. Chara. (X8R): X8R is a specific dielectric material classification defined by 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 characteristic is vital for applications exposed to significant temperature fluctuations.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the component as a Multilayer Ceramic Capacitor, known for its excellent high-frequency performance, low equivalent series resistance (ESR), and high reliability compared to other capacitor types.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for mass production and new designs, ensuring long-term supply and support.
• Rated Voltage [DC] / V (50): This specifies the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 50V rating makes it suitable for a broad range of low to medium voltage power supply and signal processing applications.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range, consistent with the X8R dielectric characteristic. It quantifies the stability of the capacitance value under varying thermal conditions, which is crucial for maintaining circuit performance.
• Operating Temp. Range / °C (-55 to 150): This defines the full spectrum of temperatures at which the capacitor is designed to operate reliably. The wide range, especially up to 150°C, makes it suitable for harsh environments where extreme temperatures are common.

Features and Benefits
