Key Specifications

• Applications: Commercial Grade
  This designation indicates that the capacitor is designed and tested to meet the rigorous performance and reliability standards required for general commercial electronic devices and systems. It signifies suitability for a broad range of products where consistent operation is critical but not as extreme as automotive or military specifications.
• Brand: TDK
  TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and other passive devices. Their brand signifies reliability, innovation, and adherence to stringent manufacturing standards, ensuring engineers receive components they can trust.
• Feature: 150°C
  This attribute highlights the capacitor’s ability to operate reliably at elevated temperatures, specifically up to 150°C. This extended temperature capability is crucial for applications in enclosed spaces, power supplies, or industrial environments where heat dissipation can be a challenge, providing a wider operational margin than standard components.
• Tolerance: ±5%
  The capacitance tolerance specifies the permissible deviation from the nominal capacitance value (680pF). A ±5% tolerance is considered a tight tolerance for ceramic capacitors, indicating high precision. This is vital in frequency-sensitive circuits, timing circuits, and filters where the exact capacitance value significantly impacts circuit performance and stability.
• L x W Size: 1.0mm x 0.5mm [EIA 0402]
  This defines the physical dimensions of the surface-mount device (SMD) capacitor. The 1.0mm x 0.5mm size corresponds to the industry-standard EIA 0402 package code. This miniature footprint is highly desirable for modern compact electronic designs, enabling higher component density on printed circuit boards (PCBs) and facilitating miniaturization of end products.
• Capacitance: 680pF
  This is the nominal electrical capacitance value of the component, measured in picofarads (pF). A 680pF capacitor is commonly used for high-frequency decoupling, resonant circuits, filtering, and timing applications where a relatively small capacitance value is required to manage signals or store charge efficiently.
• T(Max.) / mm: 0.55
  This specifies the maximum thickness of the capacitor, which is 0.55 millimeters. This thin profile is advantageous for designs with strict height constraints, such as slim consumer electronics, portable devices, and modules where vertical space on the PCB is at a premium.
• Temperature Characteristic: NP0 (C0G)
  NP0 (also known as C0G) is a highly stable dielectric material characteristic. It signifies a very low change in capacitance over a wide operating temperature range and negligible capacitance change with applied voltage or time. This makes NP0 capacitors ideal for precision applications where stable performance across varying conditions is paramount, such as in timing circuits, oscillators, and filters.
• Component Type: Ceramic Capacitor (MLCC)
  This identifies the fundamental type of capacitor. MLCCs are constructed from multiple alternating layers of ceramic dielectric and metal electrodes, offering high capacitance in a small volume, excellent frequency response, and high reliability, making them ubiquitous in modern electronics.
• Product Status: Production
  This indicates that the component is actively being manufactured and is readily available for purchase and integration into new designs. It assures designers of long-term supply and support for their products utilizing this component.
• Rated Voltage [DC] / V: 50
  This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 50V rating makes this capacitor suitable for a wide range of low to medium voltage circuits commonly found in digital and analog electronics.
• Cap. Change or Temp. Coef.: 0±30ppm/°C
  This quantifies the change in capacitance with respect to temperature. A value of 0±30ppm/°C (parts per million per degree Celsius) is exceptionally low, confirming the NP0 characteristic. It means the capacitance will vary by a maximum of only 30 parts per million for every degree Celsius change in temperature, ensuring highly stable performance.
• Operating Temp. Range / °C: -55 to 150
  This specifies the full range of ambient temperatures over which the capacitor is designed to operate reliably and meet its specified performance characteristics. An extended range from -55°C to +150°C is indicative of a robust component suitable for harsh environments, including industrial, automotive (non-critical), and outdoor applications.

Features and Benefits

• Exceptional Temperature Stability (NP0 Characteristic): The NP0 temperature characteristic ensures that the 680pF capacitance remains remarkably stable across a wide operating temperature range of -55°C to 150°C, with a minimal capacitance change of 0±30ppm/°C. This is critical for precision circuits where stable performance is paramount, such as in timing, filtering, and resonant applications, reducing design complexity and improving system reliability.
• High Precision with Tight Tolerance: With a capacitance tolerance of ±5%, this TDK MLCC offers high accuracy for its 680pF value. This precision is vital for applications requiring exact component values to achieve desired circuit performance, such as in signal processing, impedance matching, and frequency control, leading to more predictable and consistent circuit behavior.
• Compact and Space-Saving Design (EIA 0402): The miniature 1.0mm x 0.5mm (EIA 0402) footprint, combined with a maximum thickness of 0.55mm, allows for high component density on PCBs. This enables the design of smaller, lighter, and more compact electronic devices, which is a significant advantage in modern electronics where miniaturization is a key trend.
• Robust Commercial Grade Reliability: Designed for commercial-grade applications and capable of operating up to 150°C, this capacitor offers enhanced reliability and durability. It can withstand demanding operational environments, making it suitable for a broad spectrum of electronic products that require consistent and long-term performance without degradation.
