This passive component is designed to store and release electrical energy, filter noise, and stabilize voltage in a wide array of electronic circuits. As a ceramic capacitor, it utilizes a ceramic dielectric material, offering excellent frequency characteristics, high reliability, and a compact form factor. The ‘C’ in the MPN typically denotes a chip capacitor, while ‘3216’ refers to its metric dimensions, indicating a standard size widely adopted in surface-mount technology (SMT) applications. This particular model is engineered for commercial grade applications, ensuring robust performance in general electronic devices where stability and precision are paramount.

Key Specifications

• Applications: Commercial Grade
  This specification indicates that the capacitor is designed and tested to meet the requirements for general electronic products and systems. It offers a balance of performance, reliability, and cost-effectiveness suitable for a vast range of consumer, industrial, and communication devices, rather than highly specialized automotive or military applications.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components and materials. Their brand signifies a commitment to innovation, reliability, and precision engineering, making TDK components a trusted choice for electronics manufacturers worldwide.
• Feature: Mid
  While ‘Mid’ can be a broad descriptor, in the context of MLCCs, it often refers to a balance of capacitance, voltage, and size, positioning it as a versatile component suitable for a wide range of general-purpose filtering, decoupling, and timing applications without being overly specialized for ultra-high frequency or extremely high capacitance demands.
• Tolerance: ±2%
  This indicates the permissible deviation of the actual capacitance value from its nominal value. A ±2% tolerance is considered very tight for a ceramic capacitor, signifying high precision. This is crucial in applications where exact capacitance values are critical for circuit performance, such as in resonant circuits, timing circuits, or precision filters, ensuring consistent and predictable operation.
• L x W Size: 3.2mm x 1.6mm [EIA 1206]
  This specifies the physical dimensions of the capacitor. 3.2mm in length and 1.6mm in width correspond to the industry-standard EIA 1206 package size. This widely adopted surface-mount technology (SMT) footprint allows for automated assembly, making it suitable for high-volume manufacturing and compact circuit board designs.
• Capacitance: 680pF
  This is the primary electrical characteristic, representing the capacitor’s ability to store an electrical charge. 680 picofarads (pF) is a common value for filtering high-frequency noise, decoupling power lines in digital circuits, or as part of resonant tanks in RF applications, offering a good balance for many signal integrity tasks.
• T(Max.) / mm: 1
  This refers to the maximum thickness of the component, which is 1 millimeter. This dimension is critical for mechanical design and ensuring the component fits within specific height constraints on a PCB, especially in slim or compact electronic devices.
• Temperature Characteristic: C0G
  C0G is one of the most stable dielectric materials for ceramic capacitors. It indicates a very low change in capacitance over a wide temperature range, making it ideal for precision applications where temperature stability is critical. C0G capacitors are known for their excellent performance in resonant circuits, filters, and timing circuits.
• Component Type: Ceramic Capacitor (MLCC)
  This confirms the fundamental nature of the component. MLCCs are constructed by stacking multiple layers of ceramic dielectric and metal electrodes, offering high capacitance in a small volume. They are known for their high frequency response, low equivalent series resistance (ESR), and excellent reliability.
• Product Status: Production
  This indicates that the C3216C0G2J681G085AA is actively being manufactured and is readily available for purchase. This assures buyers of consistent supply and long-term availability for their designs.
• Rated Voltage [DC] / V: 630
  This is the maximum DC voltage that can be continuously applied to the capacitor without risk of dielectric breakdown. A 630V rating is relatively high for an MLCC of this size, making it suitable for applications with higher voltage rails or where significant voltage transients might occur, providing a robust safety margin.
• Capacitance Change or Temperature Coefficient: 0±30ppm/°C
  This is a precise measure of how much the capacitance changes with temperature. A value of 0±30ppm/°C (parts per million per degree Celsius) is characteristic of C0G dielectrics, indicating extremely stable capacitance over temperature variations. This minimal drift is crucial for precision applications where consistent performance across varying environmental conditions is required.
• Operating Temperature Range / °C: -55 to 125
  This specifies the range of ambient temperatures within which the capacitor is designed to operate reliably and meet its specified performance characteristics. A wide range of -55°C to 125°C highlights its robustness and suitability for demanding environments, from extreme cold to high heat, common in industrial, automotive, and outdoor electronics.
