This multi-layer ceramic capacitor is designed to store and release electrical energy, filter noise, and stabilize voltage in a wide array of electronic circuits. As a passive component, it plays a critical role in ensuring the reliable operation of various commercial-grade electronic devices by providing capacitance in a compact form factor. TDK’s expertise in material science and manufacturing precision ensures that this MLCC delivers consistent performance and long-term stability.

Key Specifications

• Apps. (Commercial Grade): This attribute signifies that the capacitor is engineered for use in general-purpose commercial electronic equipment. It indicates a balance of performance, reliability, and cost-effectiveness suitable for a broad spectrum of non-critical applications where extreme environmental conditions or life-support requirements are not present.
• Brand (TDK): TDK is a globally recognized leader in electronic components and materials, known for its innovation and quality. Specifying TDK assures buyers of a component manufactured to high industry standards with robust design and reliable performance characteristics.
• Feature (MidMega): The “MidMega” feature likely refers to TDK’s specific internal classification for MLCCs that offer a balance of capacitance and voltage in a mid-range size, often optimized for general-purpose power and signal filtering applications where a significant amount of capacitance is required without resorting to extremely large package sizes.
• Tolerance (±20%): This indicates the permissible deviation of the actual capacitance value from the nominal 680nF value. A ±20% tolerance is common for general-purpose ceramic capacitors, particularly those used in power filtering and coupling applications where precise capacitance is not as critical as in timing or resonant circuits.
• L x W Size (5.7mm x 5.0mm [EIA 2220]): This specifies the physical dimensions of the capacitor. The 5.7mm length and 5.0mm width correspond to the EIA 2220 standard package size, which is a relatively large surface-mount footprint. This larger size often accommodates higher capacitance values and/or higher voltage ratings, making it suitable for applications requiring robust power handling.
• Capacitance (680nF): This is the primary electrical characteristic, indicating the component’s ability to store charge. 680 nanofarads (0.68 microfarads) is a substantial capacitance value for a ceramic capacitor, making it suitable for bulk decoupling, filtering power rails, or energy storage in various commercial circuits.
• T(Max.) / mm (3.5): This denotes the maximum thickness of the component, which is 3.5mm. This dimension is crucial for PCB layout and enclosure design, ensuring adequate clearance and proper fit within the intended electronic assembly.
• Temp. Chara. (X7T): The X7T temperature characteristic defines how the capacitance changes over a specified operating temperature range. For X7T, the operating temperature range is -55°C to +125°C, and the capacitance change is within +22% to -33% relative to the capacitance at 25°C. This characteristic indicates suitability for applications requiring stable performance across a wide temperature spectrum.
• Component Type (Ceramic Capacitor (MLCC)): This clearly identifies the fundamental type of component. MLCCs are favored for their small size, low equivalent series resistance (ESR), low equivalent series inductance (ESL), and good high-frequency performance, making them versatile for many modern electronic designs.
• Product Status (Production): This indicates that the CKG57KX7T2W684M335JH is an active, currently manufactured part, ensuring long-term availability and support for new designs and existing production lines without concerns about obsolescence.
• Rated Voltage [DC] / V (450): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 450V rating is quite high for an MLCC, making this component suitable for applications involving higher voltage power supplies, industrial controls, or power conversion circuits.
• Cap.Change or Temp.Coef. (+22,-33%): This reiterates and quantifies the capacitance change over the operating temperature range, specifically for the X7T characteristic. It means that over the -55°C to 125°C range, the capacitance will not increase by more than 22% or decrease by more than 33% from its nominal value at room temperature.
• Operating Temp. Range / °C (-55 to 125): This specifies the full ambient temperature range within which the capacitor is designed to operate reliably and meet its specified performance characteristics. A wide range like -55°C to 125°C highlights its robustness for demanding thermal environments.

Features and Benefits

• High Voltage Capability: With a rated voltage of 450V DC, this MLCC is ideal for applications requiring robust performance in higher voltage power circuits, offering enhanced reliability and safety margins compared to lower voltage components.
• Wide Operating Temperature Range: The -55°C to 125°C operating temperature range ensures stable and reliable operation in diverse environmental conditions, from extreme cold to high heat, making it suitable for industrial and outdoor commercial equipment.
• Compact EIA 2220 Footprint: Despite its high capacitance and voltage rating, the 5.7mm x 5.0mm (EIA 2220) surface-mount package allows for efficient PCB utilization while accommodating the necessary internal structure for its performance characteristics.
• Substantial Capacitance (680nF): The 680nF capacitance value provides significant charge storage and filtering capabilities, making it effective for power supply decoupling, ripple reduction, and energy reservoir applications in commercial-grade electronics.
• TDK Quality and Reliability: Manufactured by TDK, a leading name in electronic components, this MLCC benefits from stringent quality control and advanced manufacturing processes, ensuring consistent performance and long operational lifespan.
• Commercial Grade Application: Designed specifically for commercial applications, it offers a cost-effective solution without compromising the essential performance and reliability required for general electronic devices.

Typical Applications

• Power Supply Filtering and Decoupling: The CKG57KX7T2W684M335JH is exceptionally well-suited for filtering input and output power rails in various power supply units (PSUs), AC-DC converters, and DC-DC converters. Its 680nF capacitance and 450V rating allow it to effectively smooth out voltage ripples, suppress transient noise, and provide local energy storage for integrated circuits and other loads, ensuring stable power delivery.
• Industrial Control Systems: In industrial automation and control equipment, where robust components are essential, this MLCC can be used in sensor interfaces, motor drive control circuits, and programmable logic controllers (PLCs). Its wide operating temperature range and high voltage capability make it reliable in demanding factory environments.
• LED Lighting Drivers: For commercial and industrial LED lighting applications, the capacitor can be integrated into LED driver circuits. It helps in power factor correction, input voltage filtering, and output current smoothing, contributing to the efficiency, longevity, and flicker-free operation of LED luminaires.
