The specific attributes of this TDK MLCC are tailored for commercial-grade applications, ensuring robust performance in demanding environments.

Key Specifications

This TDK MLCC boasts several critical specifications that define its performance and suitability for various applications:

Apps. (Commercial Grade): This designation indicates that the capacitor is engineered for use in general electronic equipment, consumer electronics, and industrial applications where standard reliability and performance are required. It signifies a balance between cost-effectiveness and dependable operation.

Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices. Choosing a TDK component assures engineers of consistent quality, reliability, and adherence to industry standards.

Feature (Mid): The ‘Mid’ feature typically refers to the capacitance range or performance characteristics of the capacitor within TDK’s product portfolio, often indicating a general-purpose component suitable for a broad spectrum of applications without being ultra-specialized for extreme conditions.

Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose capacitors, offering a good balance between precision and cost, suitable for many filtering, coupling, and bypass applications where exact capacitance is not critically sensitive.

L x W Size (2.0mm x 1.25mm [EIA 0805]): This refers to the physical dimensions of the surface-mount device (SMD) capacitor. The 2.0mm length and 1.25mm width correspond to the industry-standard EIA 0805 package size, making it compatible with automated pick-and-place assembly processes and suitable for compact PCB designs.

Capacitance (100nF): The nominal capacitance value of 100 nanofarads (0.1 microfarad) is a widely used value in electronics. It is ideal for decoupling power supplies, signal coupling, and basic filtering tasks in digital and analog circuits.

T(Max.) / mm (1.45): This indicates the maximum thickness of the component, which is 1.45mm. This dimension is crucial for mechanical design considerations, ensuring proper clearance and fit within an enclosure or alongside other components on a PCB.

Temp. Chara. (X7T): X7T is a temperature characteristic code defined by EIA standards. It signifies that the capacitor’s capacitance change will be within +22% to -33% over an operating temperature range of -55°C to +125°C. This characteristic makes the capacitor suitable for applications requiring stable performance across a wide temperature spectrum, albeit with a notable capacitance drift at temperature extremes.

Component Type (Ceramic Capacitor (MLCC)): This confirms the fundamental technology of the component. MLCCs are known for their small size, high reliability, and excellent high-frequency performance, making them a cornerstone in modern electronics.

Product Status (Production): This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply and support for new and existing designs.

Rated Voltage [DC] / V (250): The maximum DC voltage that can be continuously applied to the capacitor without risk of breakdown is 250 volts. This high voltage rating makes it suitable for applications in power supplies, lighting, and industrial control systems where higher voltages are present.

Cap.Change or Temp.Coef. (+22,-33%): This explicitly states the capacitance change percentage over the full operating temperature range, reinforcing the X7T characteristic. It means that the capacitance can increase by up to 22% or decrease by up to 33% from its nominal value when subjected to temperatures between -55°C and +125°C.

Operating Temp. Range / °C (-55 to 125): This wide operating temperature range signifies the capacitor’s ability to function reliably in extreme thermal conditions, from very cold environments to hot industrial settings, enhancing its versatility.
