C3216CH2E472K115AA C3216CH2E472K115AA Ceramic Capacitor (MLCC)

C3216CH2E472K115AA is a commercial-grade 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 a wide array of electronic circuits. As a Multi-Layer Ceramic Capacitor, it offers a compact form factor and reliable performance, making it a staple in modern electronics despite its ‘Obsolete’ product status, which often indicates it’s no longer in active production but may still be available through distributors for existing designs or maintenance. Its precise capacitance and voltage rating make it suitable for various general-purpose filtering, bypassing, and coupling applications in commercial electronics.

Key Specifications

This TDK ceramic capacitor boasts several critical specifications that define its performance and suitability for different designs. The ‘Apps.’ attribute indicates it is a ‘Commercial Grade’ component, meaning it is designed for general electronic applications where standard reliability and performance are required, as opposed to automotive or industrial-specific grades. The ‘Brand’ is ‘TDK’, assuring quality from a renowned manufacturer. Its ‘Feature’ is classified as ‘Mid’, suggesting it offers a balanced performance profile suitable for a broad range of typical circuit requirements without being an ultra-high-performance or specialized part. The ‘Tolerance’ of ‘±10%’ for capacitance is a standard value, indicating that the actual capacitance can vary by up to 10% from the nominal 4.7nF, which is acceptable for many non-critical timing or filtering applications. The ‘L x W Size’ is ‘3.2mm x 1.6mm [EIA 1206]’, which is a widely recognized surface-mount package size, facilitating easy integration into automated assembly processes. The ‘Capacitance’ is ‘4.7nF’ (nanofarads), a common value for signal coupling, decoupling, and filtering in digital and analog circuits. ‘T(Max.) / mm’ is ‘1.3’, specifying the maximum thickness of the component, crucial for designs with height constraints. The ‘Temp. Chara.’ is ‘CH’, which corresponds to a ‘Cap.Change or Temp.Coef.’ of ‘0±60ppm/°C’ (parts per million per degree Celsius) over the operating temperature range. This indicates a very stable capacitance with minimal drift due to temperature variations, making it ideal for applications requiring high precision. The ‘Component Type’ is clearly defined as a ‘Ceramic Capacitor (MLCC)’, and its ‘Product Status’ is ‘Obsolete’, which is important for long-term design considerations. The ‘Rated Voltage [DC] / V’ is ‘250’, meaning it can safely operate in circuits with DC voltages up to 250 volts. Finally, the ‘Operating Temp. Range / °C’ is ‘-25 to 85’, defining the environmental conditions under which the capacitor is guaranteed to perform within its specified parameters.

Features and Benefits

• Stable Performance: The CH temperature characteristic ensures minimal capacitance change over a wide operating temperature range, providing consistent circuit performance.
• Compact Size: The 1206 EIA package (3.2mm x 1.6mm) allows for space-efficient designs, crucial for miniaturized electronic devices.
• High Voltage Rating: A 250V DC rated voltage makes it suitable for applications requiring higher voltage handling capabilities than typical low-voltage components.
• Reliable Manufacturer: Produced by TDK, a reputable brand known for quality and reliability in passive components, ensuring dependable operation.
