Key Specifications

This TDK ceramic capacitor, C1608JB1E224K080AA, boasts several key specifications that define its performance and suitability for various applications:

• Applications: Commercial Grade – This designation indicates that the capacitor is designed and tested for use in standard commercial electronic equipment, offering a balance of performance and cost-effectiveness, rather than specialized high-reliability or automotive applications.
• Brand: TDK – TDK is a premier global electronics company, renowned for its extensive range of passive components, including high-quality ceramic capacitors. Their brand signifies reliability and adherence to industry standards.
• Feature: General – This describes the capacitor’s broad applicability, meaning it is not designed for a highly specialized function but rather for general-purpose filtering, coupling, decoupling, and timing applications in a wide array of circuits.
• Tolerance: ±10% – The capacitance value of 220nF is guaranteed to be within ±10% of its nominal value. This tolerance level is common for general-purpose capacitors and is acceptable for many applications where precise capacitance is not critically required.
• L x W Size: 1.6mm x 0.8mm [EIA 0603] – This specifies the physical dimensions of the surface-mount device (SMD) capacitor. The 0603 EIA standard size (0.06 x 0.03 inches) is very common, offering a good balance between miniaturization and ease of handling during assembly.
• Capacitance: 220nF – This is the primary electrical characteristic, indicating the capacitor’s ability to store charge. A value of 220 nanofarads (0.22 microfarads) is suitable for various filtering, bypass, and coupling tasks in digital and analog circuits.
• T(Max.) / mm: 0.9 – This denotes the maximum thickness of the component, which is 0.9 millimeters. This dimension is critical for designers working with strict height constraints on printed circuit boards.
• Temperature Characteristic: JB – The JB temperature characteristic (also known as X5R) indicates that the capacitance change over the operating temperature range (-25°C to 85°C) will be within ±15% from the nominal value at 25°C. This makes it suitable for applications where moderate temperature stability is required.
• Component Type: Ceramic Capacitor (MLCC) – This identifies it as a Multi-Layer Ceramic Capacitor, a type known for its small size, low equivalent series resistance (ESR), and good high-frequency performance.
• Product Status: Obsolete – This status means the manufacturer no longer produces this specific part. While new production has ceased, these components may still be available from distributors for legacy designs, repairs, or specific project needs.
• Rated Voltage [DC] / V: 25 – This is the maximum DC voltage that can be continuously applied across the capacitor without risking damage or premature failure. A 25V rating is common for circuits operating with 3.3V, 5V, 12V, or 15V power rails.
• Capacitance Change or Temp. Coef.: ±10% – This reiterates the temperature stability, specifically stating that the capacitance will not deviate by more than ±10% across the specified operating temperature range, aligning with the JB characteristic.
• Operating Temp. Range / °C: -25 to 85 – This defines the ambient temperature range within which the capacitor is designed to operate reliably and meet its specified performance characteristics. This range is typical for many commercial and industrial applications.

Features and Benefits

• Compact EIA 0603 Footprint: The small 1.6mm x 0.8mm size allows for high-density board designs, crucial for miniaturized electronic devices and space-constrained applications.
• Reliable TDK Quality: Manufactured by TDK, a leader in passive components, ensuring consistent performance and durability even for an obsolete part.
• General Purpose Utility: The ‘General’ feature and ‘Commercial Grade’ application make it highly versatile for a broad spectrum of filtering, decoupling, and timing circuits.
• Stable Performance over Temperature: With a JB (X5R) temperature characteristic and an operating range of -25°C to 85°C, it offers predictable capacitance behavior in typical environmental conditions.
• Suitable for Common Voltage Rails: A 25V rated voltage accommodates frequently used power supply levels in various electronic systems, providing ample margin for many applications.

Typical Applications

The C1608JB1E224K080AA ceramic capacitor, despite its obsolete status, remains valuable for various applications, particularly in maintenance, repair, and legacy system design:

• Decoupling and Bypass Filtering: Essential for digital circuits, this capacitor can be placed near IC power pins to filter out high-frequency noise from the power supply lines, ensuring stable voltage delivery to sensitive components and preventing signal integrity issues. Its 220nF capacitance is well-suited for bypassing mid-frequency noise.
• Signal Coupling and DC Blocking: In analog circuits, it can be used to couple AC signals between stages while blocking unwanted DC bias voltages. This ensures that the DC operating points of different amplifier stages do not interfere with each other, maintaining proper signal flow.
• Timing Circuits and Oscillators: While not a precision component, its capacitance can be used in RC timing circuits or simple oscillator designs where a ±10% tolerance is acceptable. It contributes to setting time constants for delays or oscillation frequencies.
• Noise Reduction in Power Supplies: Integrated into power supply output stages, it helps smooth out ripple voltages and filter transient noise, contributing to a cleaner and more stable power output for downstream components. Its compact size makes it ideal for distributed filtering.
• General-Purpose Filtering in Consumer Electronics: From home appliances to older computing peripherals, this capacitor can be found in various consumer electronic devices for general filtering tasks, ensuring reliable operation and mitigating electromagnetic interference (EMI).
