C1608JB2A472M080AA C1608JB2A472M080AA Ceramic Capacitor (MLCC)

C1608JB2A472M080AA is a commercial-grade multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. This passive component is designed for surface-mount applications, offering reliable capacitance in a compact form factor. MLCCs like the C1608JB2A472M080AA are fundamental in modern electronics, used for decoupling, filtering, and energy storage in a wide array of circuits due to their small size, high reliability, and excellent frequency characteristics.

Key Specifications

This TDK MLCC boasts several critical specifications that define its performance and suitability for various designs:

• Apps. (Commercial Grade): This designation indicates that the capacitor is designed for general-purpose electronic equipment where standard reliability and performance are sufficient, making it a cost-effective choice for a broad range of products.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, ensuring reliability and performance for this MLCC.
• Feature (Mid): The ‘Mid’ feature typically refers to the dielectric material’s characteristics, often indicating a balance between capacitance stability, temperature performance, and cost, suitable for a wide range of general applications.
• Tolerance (±20%): This specifies the permissible deviation of the actual capacitance value from the nominal 4.7nF. A ±20% tolerance is common for general-purpose capacitors, indicating it’s suitable for applications where precise capacitance is not critically essential.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This is the physical dimension of the capacitor, corresponding to the industry-standard 0603 package size. This small footprint is ideal for miniaturized electronic devices and high-density PCB layouts.
• Capacitance (4.7nF): The nominal capacitance value of 4.7 nanofarads (nF) is a common value used for various signal coupling, decoupling, and filtering tasks in digital and analog circuits.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is crucial for mechanical design and ensuring the component fits within specific height constraints on a PCB.
• Temp. Chara. (JB): The ‘JB’ temperature characteristic refers to the dielectric material’s stability over temperature. According to EIA standards, JB dielectric typically exhibits a capacitance change of ±10% over the operating temperature range, making it suitable for applications where moderate temperature stability is acceptable.
• Component Type (Ceramic Capacitor (MLCC)): This confirms it is a Multilayer Ceramic Capacitor, known for its compact size, high frequency performance, and reliability.
• Product Status (Obsolete): While the component is listed as obsolete, it may still be available through distributors with existing stock. For new designs, it is advisable to seek a suitable replacement.
• Rated Voltage [DC] / V (100): This specifies the maximum DC voltage that can be continuously applied across the capacitor without breakdown. A 100V rating provides a good margin for many common circuit voltages.
• Cap.Change or Temp.Coef. (±10%): This reiterates the capacitance change over the specified operating temperature range, directly linked to the ‘JB’ temperature characteristic, ensuring predictable performance.
• Operating Temp. Range / °C (-25 to 85): This defines the ambient temperature range within which the capacitor is designed to operate reliably, covering typical indoor and some outdoor commercial environments.

Features and Benefits

• Compact 0603 Package: The small 1.6mm x 0.8mm footprint allows for high-density mounting, crucial for miniaturized electronic devices and space-constrained applications.
• Reliable TDK Quality: Manufactured by TDK, a leader in passive components, ensuring consistent quality, performance, and long-term reliability for commercial-grade applications.
• Versatile 4.7nF Capacitance: The 4.7nF value is widely applicable for a variety of circuit functions, including signal coupling, high-frequency bypass, and filtering, offering design flexibility.
• 100V DC Rated Voltage: Provides a robust voltage rating suitable for many general-purpose circuits, offering a good safety margin against voltage spikes.
• Moderate Temperature Stability (JB Characteristic): The JB temperature characteristic ensures predictable capacitance performance within a typical commercial operating temperature range, suitable for non-critical applications.

Typical Applications

The C1608JB2A472M080AA MLCC finds its utility in a diverse range of electronic systems, including:

• General Purpose Decoupling: Essential for power supply decoupling in microcontrollers, operational amplifiers, and other ICs, preventing voltage fluctuations and ensuring stable operation by providing local energy storage.
• Signal Filtering: Used in various analog and digital filter circuits to remove unwanted noise or to pass specific frequency bands, contributing to signal integrity in audio equipment, sensors, and communication systems.
• Resonant Circuits: Can be integrated into LC resonant circuits for frequency selection or oscillation in applications such as RF modules, tuners, and timing circuits, though its tolerance might limit high-precision uses.
• Timing Circuits: Employed in conjunction with resistors to create RC timing networks for delays, pulse generation, or oscillator circuits in consumer electronics, industrial controls, and automotive systems.
• Coupling/Blocking: Used to block DC current while allowing AC signals to pass between different stages of an amplifier or signal processing chain, preventing DC bias interference.

In summary, the C1608JB2A472M080AA from TDK is a versatile commercial-grade MLCC, offering a balance of performance and cost-effectiveness for a wide array of electronic designs.
