Key Specifications

This TDK MLCC boasts several critical specifications that define its performance and suitability for various applications. The ‘Apps.’ attribute indicates it is a ‘Commercial Grade’ component, meaning it is designed for general-purpose electronic devices and systems where standard reliability and performance are required, as opposed to specialized automotive or medical grades. The ‘Brand’ is TDK, ensuring a product from a reputable manufacturer known for quality and innovation in passive components. Its ‘Feature’ is ‘General’, further emphasizing its broad applicability. A ‘Tolerance’ of ‘±20%’ on its capacitance value means that the actual capacitance can vary by up to 20% from the nominal 15µF, which is common for X7R dielectric types and acceptable for many filtering and decoupling applications. The ‘L x W Size’ is ‘3.2mm x 2.5mm [EIA 1210]’, referring to its physical dimensions in millimeters and its corresponding industry-standard EIA case code, indicating a relatively larger surface-mount package suitable for higher capacitance values and power handling. The ‘Capacitance’ is a substantial ’15µF’, providing significant charge storage capacity for decoupling power rails or filtering low-frequency signals. ‘T(Max.) / mm’ at ‘2.8’ specifies the maximum thickness of the component, crucial for PCB layout and enclosure design. The ‘Temp. Chara.’ is ‘X7R’, a common ceramic dielectric type known for its stable capacitance over a wide temperature range, making it suitable for general-purpose applications. The ‘Component Type’ is clearly identified as a ‘Ceramic Capacitor (MLCC)’. Its ‘Product Status’ is ‘Production’, confirming it is an actively manufactured and readily available part. The ‘Rated Voltage [DC] / V’ is ’16’, indicating the maximum continuous DC voltage that can be applied across the capacitor without risk of breakdown. ‘Cap.Change or Temp.Coef.’ of ‘±15%’ over the operating temperature range is characteristic of X7R dielectrics, meaning the capacitance will not deviate by more than 15% from its 25°C value across its full operating temperature range. Finally, the ‘Operating Temp. Range / °C’ from ‘-55 to 125’ signifies its robust performance across extreme thermal conditions, allowing its use in diverse environments.
