Key Specifications

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

Applications: High Reliability Grade – This designation signifies that the capacitor is engineered for use in critical systems where failure is not an option, often found in automotive, industrial, or medical electronics. It implies enhanced testing and quality control measures during manufacturing.

Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Choosing a TDK component ensures a certain level of reliability and performance backed by extensive research and development.

Feature: AEC-Q200 Mid – AEC-Q200 is a global standard for stress test qualification for passive electronic components used in automotive applications. The “Mid” designation indicates that this component meets a specific level of these rigorous automotive-grade qualifications, ensuring its suitability for non-safety-critical automotive systems and other harsh environments.

AEC-Q200: YES – Explicitly confirming its compliance with the AEC-Q200 standard, this attribute underscores the component’s robustness and reliability under demanding conditions, making it suitable for automotive and other high-stress applications.

Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value of 330nF. A ±10% tolerance is common for general-purpose and many automotive applications, providing a good balance between precision and cost-effectiveness.

L x W Size: 2.0mm x 1.25mm [EIA 0805] – This indicates the physical dimensions of the capacitor. The EIA 0805 standard size is a widely adopted surface-mount technology (SMT) package, offering a compact footprint suitable for miniaturized electronic designs while still being relatively easy to handle during assembly compared to smaller sizes.

Capacitance: 330nF – This is the primary electrical characteristic, representing the component’s ability to store an electrical charge. A 330nF capacitance is suitable for various filtering, coupling, decoupling, and timing applications in electronic circuits.

T(Max.) / mm: 1.45 – This refers to the maximum thickness of the component, which is crucial for mechanical design and ensuring proper fit within a PCB assembly, especially in space-constrained applications.

Temp. Chara.: X7S – The X7S temperature characteristic defines how the capacitance changes over a specified temperature range. For X7S, the capacitance change is within ±22% over an operating temperature range of -55°C to +125°C, making it suitable for applications requiring stable performance across wide temperature variations.

Component Type: Ceramic Capacitor (MLCC) – This identifies the fundamental type of capacitor. MLCCs are known for their small size, low equivalent series resistance (ESR), low equivalent series inductance (ESL), and excellent high-frequency characteristics.

Product Status: Obsolete – This status indicates that the manufacturer, TDK, no longer produces this specific part. While still available through distributors with existing stock, it is advisable for new designs to consider alternative, currently active components.

Rated Voltage [DC] / V: 100 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 100V rating provides a good margin for many common circuit designs, especially in automotive and industrial environments where voltage spikes can occur.

Cap.Change or Temp.Coef.: ±22% – This reiterates the capacitance change over the specified temperature range, directly linked to the X7S temperature characteristic. It’s a critical parameter for applications where capacitance stability with temperature is paramount.

Operating Temp. Range / °C: -55 to 125 – This specifies the full temperature range over which the capacitor is designed to operate reliably. The wide range from -55°C to +125°C highlights its suitability for harsh environments, including automotive under-the-hood applications and industrial equipment operating in extreme conditions.
