Key Specifications

This TDK ceramic capacitor boasts several critical specifications that define its performance and suitability for specific applications:

• Applications: High Reliability Grade – This designation indicates that the capacitor is engineered for environments where failure is not an option, such as critical automotive systems, industrial control, or medical devices. It implies rigorous testing and manufacturing standards beyond typical commercial-grade components.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand signifies a commitment to innovation and reliability in the electronics industry.
• Feature: AEC-Q200 General – This feature confirms that the component meets the Automotive Electronics Council’s AEC-Q200 standard for passive components. This certification is vital for parts used in automotive applications, ensuring they can withstand the harsh conditions (temperature, vibration, humidity) typically found in vehicles.
• AEC-Q200: YES – Explicitly states compliance with the AEC-Q200 standard, reinforcing its suitability for automotive and other demanding environments.
• Tolerance: ±10% – This value specifies the permissible deviation of the actual capacitance from its nominal value. A ±10% tolerance is common for general-purpose and semi-precision applications, indicating a reasonable level of accuracy for charge storage.
• L x W Size: 1.6mm x 0.8mm [EIA 0603] – This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The EIA 0603 standard size (0.06 x 0.03 inches) is a very common and compact footprint, allowing for high-density circuit board designs, which is crucial for miniaturization in modern electronics.
• Capacitance: 68nF – The nominal capacitance value of 68 nanofarads (nF) determines the amount of electrical charge the capacitor can store. This value is suitable for a wide range of filtering, coupling, and bypass applications in electronic circuits.
• T(Max.) / mm: 0.9 – This indicates the maximum thickness of the component, which is 0.9 millimeters. This thin profile is beneficial for applications with strict height restrictions, contributing to overall device slimness.
• Temp. Chara.: X7R – X7R is a common dielectric material for ceramic capacitors, known for its relatively stable capacitance over a wide temperature range. It is considered a “temperature stable” dielectric, making it suitable for applications where performance must be consistent despite temperature fluctuations.
• Component Type: Ceramic Capacitor (MLCC) – Confirms it is a Multi-Layer Ceramic Capacitor, which are widely used due to their small size, high capacitance values, and excellent high-frequency performance.
• Product Status: Obsolete – While the product is obsolete, it means it is no longer in active production by the manufacturer. However, it may still be available through distributors for replacement parts, maintenance, or for designs that have already incorporated this specific component.
• Rated Voltage [DC] / V: 50 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 50V rating makes it suitable for many low to medium voltage applications.
• Cap.Change or Temp.Coef.: ±15% – This specifies the maximum percentage change in capacitance over the operating temperature range for an X7R dielectric. A ±15% change is typical for X7R, indicating good stability for general-purpose applications.
• Operating Temp. Range / °C: -55 to 125 – This broad temperature range signifies the capacitor’s ability to operate reliably from extremely cold conditions to very hot environments, further underscoring its high-reliability grade and suitability for automotive and industrial use.

Features and Benefits

• Exceptional Temperature Stability: The X7R dielectric and wide operating temperature range of -55 to 125°C ensure consistent performance in varying thermal conditions, crucial for outdoor or engine compartment electronics.
• Automotive Grade Reliability: AEC-Q200 qualification makes this capacitor ideal for demanding automotive applications, providing assurance against common environmental stressors like vibration, temperature extremes, and humidity.
• Compact Footprint: The EIA 0603 (1.6mm x 0.8mm) size allows for significant space savings on printed circuit boards, enabling the design of smaller, more portable, and higher-density electronic devices.
• Robust Voltage Handling: With a 50V DC rated voltage, the CGJ3E2X7R1H683K080AA is well-suited for a broad spectrum of low to medium voltage circuits, offering a good margin of safety in many applications.
• Trusted Manufacturer: Produced by TDK, a globally recognized leader in electronic components, ensuring high manufacturing quality and adherence to industry standards.
