C1608JB2A223K080AA C1608JB2A223K080AA Ceramic Capacitor (MLCC)

C1608JB2A223K080AA is a commercial-grade multilayer ceramic capacitor (MLCC) manufactured by TDK, a global leader in electronic components. 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 between conductive plates, offering high volumetric efficiency and reliability. The MLCC construction allows for a compact footprint, making it suitable for miniaturized electronic devices. While the product status indicates ‘Obsolete’, it remains a critical component for maintenance, repair, and legacy system integration, often sought after for its specific characteristics and TDK’s renowned quality.

Key Specifications

The attributes of the C1608JB2A223K080AA are crucial for understanding its performance and suitability for various applications:

• Applications: Commercial Grade – This designation indicates the capacitor is designed for general electronic applications where standard reliability and performance are required, as opposed to automotive or high-reliability industrial uses.
• Brand: TDK – TDK is a highly respected Japanese multinational electronics company known for its expertise in magnetic materials and electronic components, ensuring a high standard of quality and engineering.
• Feature: Mid – This likely refers to its mid-range capacitance value and voltage rating within TDK’s broader MLCC portfolio, offering a balance of performance and size.
• Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from the nominal 22nF. A ±10% tolerance is common for general-purpose applications, indicating a reasonable level of precision for filtering and coupling tasks.
• L x W Size: 1.6mm x 0.8mm [EIA 0603] – This is the physical dimension of the surface-mount device (SMD) capacitor. The 0603 EIA standard size is very small, enabling high-density PCB designs and miniaturization in electronic products.
• Capacitance: 22nF – This is the nominal electrical charge storage capacity of the capacitor, measured in nanofarads. A 22nF capacitor is typically used for decoupling, bypass, and filtering applications in digital and analog circuits.
• T(Max.) / mm: 0.9 – This indicates the maximum thickness of the component, which is 0.9 millimeters. This dimension is critical for mechanical design and ensuring the component fits within specific height constraints on a PCB.
• Temp. Chara.: JB – The JB temperature characteristic (also known as X5R) defines how the capacitance changes with temperature. For JB/X5R, the capacitance change is within ±15% over an operating temperature range of -55°C to +85°C, making it suitable for many commercial and industrial applications where moderate temperature stability is acceptable.
• Component Type: Ceramic Capacitor (MLCC) – This confirms it is a multilayer ceramic capacitor, known for its small size, high frequency performance, and low equivalent series resistance (ESR).
• Product Status: Obsolete – While the part is obsolete, it means it is no longer in active production by the manufacturer. However, it may still be available through distributors for existing designs or repair needs.
• Rated Voltage [DC] / V: 100 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 100V rating provides a good margin for many common 5V, 12V, or 24V power supply lines.
• Cap.Change or Temp.Coef.: ±10% – This reiterates the capacitance change over the specified operating temperature range, aligning with the JB temperature characteristic for a more precise understanding of its thermal performance.
• Operating Temp. Range / °C: -25 to 85 – This specifies the ambient temperature range within which the capacitor is designed to operate reliably and meet its electrical specifications. This range is typical for commercial-grade electronic equipment.

Features and Benefits

• Compact 0603 Footprint: The small 1.6mm x 0.8mm size allows for high-density mounting on PCBs, crucial for miniaturized electronic devices and space-constrained applications.
• Reliable TDK Quality: Manufactured by TDK, a reputable industry leader, ensuring consistent performance and adherence to quality standards, even for an obsolete part.
• Versatile 22nF Capacitance: The 22nF value is highly versatile, suitable for a broad range of decoupling, bypassing, and filtering tasks in both digital and analog circuits.
• 100V DC Rated Voltage: Provides a robust voltage rating, making it suitable for applications with higher voltage rails or where a significant safety margin is desired over typical low-voltage logic circuits.
• JB/X5R Temperature Stability: Offers predictable capacitance performance across a common commercial temperature range (-25 to 85°C), ensuring stable circuit operation in varied environments.

Typical Applications

This C1608JB2A223K080AA ceramic capacitor, despite its obsolete status, finds utility in various electronic systems requiring reliable capacitance for specific functions:

• General Purpose Decoupling: Essential for power supply lines in microcontrollers, operational amplifiers, and other ICs to suppress voltage fluctuations and provide stable power, improving overall circuit stability and noise immunity.
• Signal Filtering: Used in analog and digital signal paths to filter out unwanted high-frequency noise, ensuring signal integrity in communication systems, audio circuits, and data acquisition systems.
• Timing Circuits: Can be integrated into RC timing circuits for oscillators, timers, and delay lines, where its stable capacitance contributes to precise timing intervals.
• Bypass Capacitors: Placed across power and ground pins of integrated circuits to provide a local reservoir of charge, quickly supplying current demands during switching events and preventing voltage droop.
• Legacy System Maintenance and Repair: Due to its obsolete status, this component is particularly valuable for repairing older electronic equipment where the original part is no longer manufactured, ensuring the continued operation of existing systems.

Summary

The C1608JB2A223K080AA is a reliable 22nF, 100V commercial-grade MLCC from TDK, featuring a compact 0603 package.
