It signifies a balance of performance, reliability, and cost-effectiveness suitable for a broad array of consumer and industrial applications, rather than highly specialized or extreme environment uses.
• Brand: TDK: TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components and materials. Specifying TDK assures buyers of a product backed by extensive research, development, and manufacturing excellence, leading to reliable and consistent performance.
• Feature: 150°C: This attribute highlights the capacitor’s ability to operate reliably at elevated temperatures, up to 150°C. This extended temperature capability is critical for applications in harsh environments or where significant heat generation is expected, such as automotive electronics, power supplies, or industrial control systems, ensuring stable operation where standard components might fail.
• Tolerance: ±10%: The capacitance tolerance of ±10% indicates the permissible deviation from the nominal capacitance value of 470nF. A ±10% tolerance is common for general-purpose applications where precise capacitance is not overly critical, offering a good balance between performance and cost.
• L x W Size: 3.2mm x 1.6mm [EIA 1206]: This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The 3.2mm x 1.6mm size corresponds to the industry-standard EIA 1206 package code. This compact footprint is highly desirable for modern electronic designs, enabling miniaturization and high-density PCB layouts.
• Capacitance: 470nF: This is the nominal electrical capacitance of the component, measured in nanofarads (nF). A capacitance of 470nF is suitable for various filtering, decoupling, and timing applications, providing sufficient charge storage for moderate frequency operations.
• T(Max.) / mm: 1: This indicates the maximum thickness of the component, which is 1mm. This dimension is crucial for mechanical design and PCB assembly, ensuring proper fit within height constraints, especially in slim electronic devices.
• Temp. Chara.: X8R: X8R is a specific dielectric material classification for ceramic capacitors, defined by its temperature stability. An X8R dielectric ensures that the capacitance change is within ±15% over an operating temperature range of -55°C to +150°C. This makes it superior to X7R for high-temperature applications, offering enhanced stability across a wider thermal spectrum.
• Component Type: Ceramic Capacitor (MLCC): This confirms the fundamental type of the component. MLCCs are known for their high frequency performance, low equivalent series resistance (ESR), and compact size, making them ideal for decoupling, filtering, and resonant circuits.
• Product Status: Production: This status indicates that the C3216X8R1E474K085AA is actively being manufactured and is readily available for purchase in volume. This is important for long-term project planning and supply chain reliability.
• Rated Voltage [DC] / V: 25: This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 25V rating makes this capacitor suitable for low to medium voltage circuits commonly found in digital and analog electronics.
• Cap.Change or Temp.Coef.: ±15%: This reiterates the capacitance change over the specified temperature range, which is a defining characteristic of the X8R dielectric. It means the capacitance will not deviate by more than ±15% from its nominal value across its full operating temperature range, ensuring stable circuit performance.
• Operating Temp. Range / °C: -55 to 150: This specifies the full range of ambient temperatures within which the capacitor is guaranteed to operate within its specified electrical parameters. The wide range, particularly the high upper limit of 150°C, underscores its robustness for demanding thermal environments.
