Key Specifications

This TDK C3216X8R1H684K160AB capacitor boasts several key attributes that define its operational capabilities and suitability for various designs:

• Apps. (Commercial Grade): This designation indicates that the capacitor is designed and tested to meet the rigorous demands of commercial electronic applications, ensuring reliability and performance in standard industrial and consumer products, unlike automotive or medical grades which have even stricter requirements.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, ensuring that this capacitor benefits from extensive research, development, and stringent manufacturing standards.
• Feature (150°C): A standout feature, this indicates the capacitor’s ability to operate reliably at temperatures up to 150°C. This extended temperature capability is critical for applications in hot environments or where significant heat generation occurs within the circuit.
• Tolerance (±10%): This specifies that the actual capacitance value will be within ±10% of the nominal 680nF value. A ±10% tolerance is common for general-purpose capacitors and suitable for many applications where precise capacitance is not overly critical.
• L x W Size (3.2mm x 1.6mm [EIA 1206]): This refers to the physical dimensions of the surface-mount component. The 3.2mm length and 1.6mm width correspond to the industry-standard EIA 1206 package size, making it compatible with automated pick-and-place assembly processes and common PCB footprints.
• Capacitance (680nF): The nominal capacitance value is 680 nanofarads (0.68 microfarads). This value is suitable for various filtering, decoupling, and timing applications, offering a good balance between physical size and charge storage capacity.
• T(Max.) / mm (1.8): This indicates the maximum thickness of the component, which is 1.8mm. This dimension is important for mechanical design considerations, especially in compact or height-constrained electronic assemblies.
• Temp. Chara. (X8R): The X8R dielectric material characteristic signifies a capacitor that can operate over a wide temperature range of -55°C to +150°C with a maximum capacitance change of ±15%. This makes it superior to X7R for high-temperature applications.
• Component Type (Ceramic Capacitor (MLCC)): This confirms it is a Multi-Layer Ceramic Capacitor, known for its high volumetric efficiency, low equivalent series resistance (ESR), and excellent high-frequency performance.
• Product Status (Production): This indicates that the component is actively being manufactured and is readily available for new designs and mass production, ensuring long-term supply stability.
• Rated Voltage [DC] / V (50): The capacitor is rated for a maximum DC voltage of 50V. This is the maximum continuous DC voltage that can be applied across the capacitor without risking dielectric breakdown or degradation.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range, confirming the stability offered by the X8R dielectric.
• Operating Temp. Range / °C (-55 to 150): This wide operating temperature range from -55°C to +150°C is a critical feature, allowing the capacitor to function reliably in extreme thermal conditions, from very cold environments to significantly hot ones.

Features and Benefits

• Extended High-Temperature Operation: With an operating temperature range up to 150°C and X8R dielectric, this capacitor is perfectly suited for demanding environments where standard capacitors would fail, ensuring circuit integrity and longevity.
