Key Specifications

The attributes of the C1608X8R1H333M080AE are critical for understanding its capabilities and suitability for various designs:

• Apps. (Commercial Grade): This designation signifies that the capacitor is engineered to meet the rigorous demands of general commercial electronic products, offering a balance of performance, reliability, and cost-effectiveness for a broad spectrum of applications, unlike automotive or industrial grades that might have stricter qualification processes.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Choosing a TDK component ensures adherence to stringent manufacturing standards and reliable performance.
• Feature (150°CSoft): This unique feature highlights the capacitor’s ability to operate reliably at elevated temperatures up to 150°C, often indicating special internal construction or dielectric materials that mitigate thermal stress and ensure long-term stability in harsh thermal environments.
• Tolerance (±20%): A capacitance tolerance of ±20% means the actual capacitance value can vary by up to 20% from the nominal 33nF. This is a common tolerance for general-purpose ceramic capacitors and is acceptable in many non-precision timing or filtering applications.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This specifies the physical dimensions of the surface-mount device (SMD). The 0603 package is a widely adopted standard in electronics, offering a good balance between miniaturization and ease of handling during assembly.
• Capacitance (33nF): This is the fundamental electrical property of the capacitor, indicating its ability to store an electrical charge. A 33nF capacitor is commonly used for decoupling, filtering, and bypassing applications in various digital and analog circuits.
• T(Max.) / mm (0.95): This refers to the maximum thickness of the component, which is 0.95mm. This dimension is crucial for mechanical design and ensuring proper clearance in compact PCB layouts.
• Temp. Chara. (X8R): The X8R temperature characteristic indicates that the capacitor’s capacitance change is within ±15% over an operating temperature range of -55°C to +150°C. This makes it suitable for applications requiring stable capacitance over a wide temperature spectrum, especially in high-temperature environments.
• Component Type (Ceramic Capacitor (MLCC)): This identifies the component as a Multilayer Ceramic Capacitor, known for its small size, high frequency performance, and reliability, making it a staple in modern electronics.
• Product Status (Production(NRND)): “Production (NRND)” means the component is currently in active production but is designated as “Not Recommended for New Designs.” While still available, designers should consider newer alternatives for future projects, though it remains suitable for existing designs and maintenance.
• Rated Voltage [DC] / V (50): This is the maximum DC voltage that can be continuously applied across the capacitor without risk of dielectric breakdown. Operating within this limit is essential for the capacitor’s longevity and reliability.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified temperature range, directly correlating with the X8R characteristic. It signifies the stability of the capacitance value under varying thermal conditions.
• Operating Temp. Range / °C (-55 to 150): This defines the full range of ambient temperatures within which the capacitor is designed to operate reliably, extending from extreme cold to very high heat, consistent with its X8R characteristic and 150°CSoft feature.

Features and Benefits

• High-Temperature Stability (X8R Characteristic & 150°CSoft): The C1608X8R1H333M080AE offers exceptional capacitance stability across a broad temperature range from -55°C to 150°C, making it ideal for applications exposed to significant thermal variations or high operating temperatures. The “150°CSoft” feature further enhances its robustness in such conditions.
• Compact 0603 Package: With its small 1.6mm x 0.8mm footprint, this MLCC enables miniaturization of electronic circuits, allowing for higher component density on PCBs and contributing to smaller, lighter end products.
• Reliable TDK Quality: Manufactured by TDK, a leader in passive components, this capacitor benefits from stringent quality control and advanced manufacturing processes, ensuring high reliability and consistent performance in demanding commercial applications.
• Versatile Commercial Grade: Designed for commercial applications, it provides a robust and cost-effective solution for a wide array of electronic devices, balancing performance requirements with economic considerations.

Typical Applications

• Power Supply Decoupling: The C1608X8R1H333M080AE is frequently used for decoupling power lines in microcontrollers, FPGAs, and other integrated circuits. Its 33nF capacitance helps to smooth out voltage fluctuations and suppress high-frequency noise, ensuring stable power delivery to sensitive digital and analog components.
• Signal Filtering: In various communication and data processing circuits, this capacitor can be employed in low-pass or high-pass filter configurations to remove unwanted frequency components from signals, improving signal integrity and reducing interference.
• Timing and Oscillators: While its ±20% tolerance might not suit highly precise timing circuits, it can be used in less critical timing applications or in conjunction with other components to form RC oscillators or delay circuits where some variation is acceptable.
• General-Purpose Bypass: It serves as an effective bypass capacitor in many analog and digital circuits, shunting AC noise and ripple to ground, thereby preventing noise propagation between different stages of an electronic system.
• Automotive Infotainment and Telematics (Non-Critical): Given its 150°C operating capability, it can be considered for non-safety-critical applications within automotive infotainment systems, telematics units, or other modules where high ambient temperatures are encountered but full automotive qualification is not strictly required.

In summary, the C1608X8R1H333M080AE from TDK is a reliable, high-temperature ceramic capacitor suitable for a wide range of commercial applications. Its compact size, 50V rating, and X8R temperature characteristics make it an excellent choice for designs requiring stable performance in challenging thermal environments.
