C1608JB2A222M080AA C1608JB2A222M080AA Ceramic Capacitor (MLCC)

C1608JB2A222M080AA 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 various electronic circuits. Its compact surface-mount design, specifically the EIA 0603 package, makes it suitable for high-density applications where space is at a premium. While the C1608JB2A222M080AA is now marked as obsolete, it represents a common type of capacitor widely used in a broad spectrum of commercial electronic devices, providing essential functions for circuit integrity and performance.

Key Specifications

This TDK ceramic capacitor boasts several critical specifications that define its operational characteristics and suitability for specific applications. The ‘Apps.’ attribute indicates it is a ‘Commercial Grade’ component, meaning it is designed for general-purpose electronic devices where standard reliability and performance are required, as opposed to automotive or high-reliability industrial applications. The ‘Brand’ is ‘TDK’, assuring quality from a renowned manufacturer. Its ‘Feature’ is ‘Mid’, suggesting it offers a balanced performance profile without being optimized for extreme high-frequency or high-capacitance applications. The ‘Tolerance’ of ‘±20%’ on its capacitance value means that the actual capacitance can vary by up to 20% from the nominal 2.2nF, which is acceptable for many non-precision timing or filtering applications. The ‘L x W Size’ is ‘1.6mm x 0.8mm [EIA 0603]’, a standard surface-mount package size that is widely adopted for its balance of miniaturization and ease of handling during assembly. The ‘Capacitance’ is ‘2.2nF’ (nanofarads), a common value for decoupling, filtering, and timing circuits. ‘T(Max.) / mm’ refers to the maximum thickness of the component, which is ‘0.9mm’, crucial for board layout and clearance considerations in compact designs. The ‘Temp. Chara.’ is ‘JB’, indicating a specific temperature characteristic that defines how the capacitance changes with temperature. For JB characteristics, the ‘Cap.Change or Temp.Coef.’ is ‘±10%’, meaning the capacitance can vary by up to 10% over the specified operating temperature range. The ‘Component Type’ is clearly identified as a ‘Ceramic Capacitor (MLCC)’, highlighting its dielectric material and construction. The ‘Product Status’ is ‘Obsolete’, which is an important consideration for new designs but does not preclude its use for repair or maintenance of existing systems. The ‘Rated Voltage [DC] / V’ is ‘100V’, specifying the maximum DC voltage that can be continuously applied across the capacitor without breakdown. Finally, the ‘Operating Temp. Range / °C’ is ‘-25 to 85°C’, defining the ambient temperature range within which the capacitor is designed to operate reliably.

Typical Applications

The C1608JB2A222M080AA, despite its obsolete status, represents a class of MLCCs that are fundamental to many electronic systems. One primary application is **decoupling in digital and analog circuits**. Here, it is placed close to IC power pins to provide a local reservoir of charge, smoothing out voltage fluctuations caused by rapid current demands and preventing noise from propagating across the power supply. Another common use is in **filtering applications**, such as low-pass or high-pass filters, where it works in conjunction with resistors or inductors to selectively pass or block certain frequency ranges, crucial for signal integrity in audio or data communication lines. It is also frequently employed in **timing circuits**, particularly in RC oscillators or delay lines, where its capacitance, along with a resistor, determines the time constant for charging and discharging, influencing the frequency or delay of a signal. Furthermore, these capacitors are vital in **voltage stabilization circuits**, helping to maintain a steady voltage output from power supplies by shunting high-frequency noise to ground. Lastly, in **impedance matching networks**, MLCCs can be used to optimize power transfer between different stages of a circuit, especially in RF applications, though the ‘Mid’ feature suggests it’s not specifically optimized for very high RF frequencies. In summary, the C1608JB2A222M080AA is a TDK commercial-grade ceramic capacitor with a 2.2nF capacitance and 100V rating in an EIA 0603 package. While obsolete, its specifications highlight its utility in diverse commercial electronic applications requiring compact, reliable passive components for filtering, decoupling, and voltage stabilization.
