Key Specifications

• Apps. (Commercial Grade): This designation indicates that the capacitor is designed and tested for use in a wide range of commercial electronic products. It signifies a balance of performance, reliability, and cost-effectiveness suitable for general-purpose applications, ensuring stable operation in typical operating environments rather than specialized high-reliability or automotive contexts.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components and materials. Specifying TDK assures buyers of a product manufactured to stringent quality standards, benefiting from extensive research and development in capacitor technology.
• Feature (General): This attribute highlights the capacitor’s suitability for a broad spectrum of general electronic applications. It implies that the component is not specialized for a particular niche but offers balanced performance characteristics for common circuit functions like filtering, bypassing, and coupling.
• Tolerance (±10%): The capacitance tolerance specifies the permissible deviation from the nominal capacitance value. A ±10% tolerance for this 1μF capacitor means its actual capacitance will fall between 0.9μF and 1.1μF. This level of precision is common for general-purpose applications where exact capacitance values are not critically stringent but consistent performance is required.
• Capacitance (1μF): This is the primary electrical characteristic, indicating the capacitor’s ability to store charge. A 1 microfarad (μF) capacitance is a common value used in many circuits for tasks such as power supply decoupling, timing circuits, and signal filtering, providing significant charge storage capacity in a compact form factor.
• F(Nom.) / mm (2.5): This refers to the nominal lead pitch or the distance between the centers of the leads, which is 2.5mm. This standard dimension is crucial for PCB layout and ensures compatibility with standard prototyping boards and automated assembly processes.
• L(Max.) / mm (4): This specifies the maximum length of the capacitor body, excluding the leads, as 4mm. This dimension is vital for mechanical design and space planning on printed circuit boards, ensuring the component fits within designated areas.
• T(Max.) / mm (2.5): This indicates the maximum thickness or height of the capacitor body, excluding the leads, as 2.5mm. Along with length and width, this dimension is critical for determining the overall volumetric footprint of the component, especially in designs with height restrictions.
• Temp. Chara. (X5R): X5R is a ceramic dielectric material classification that defines the capacitor’s temperature stability. X5R capacitors are suitable for a wide operating temperature range from -55°C to +85°C, with a maximum capacitance change of ±15% over this range. This makes them ideal for commercial and industrial applications where moderate temperature variations are expected.
• W(Max.) / mm (5.5): This specifies the maximum width of the capacitor body, excluding the leads, as 5.5mm. This dimension, along with length and thickness, completes the physical profile of the component, essential for mechanical design and ensuring proper fit on a PCB.
• Component Type (Ceramic Capacitor (Leaded MLCC)): This precisely identifies the component as a Multi-Layer Ceramic Capacitor with radial leads. Leaded MLCCs are known for their excellent high-frequency characteristics, low ESR, and high reliability, making them superior to older capacitor technologies for many applications.
• Product Status (Production(NRND)): NRND stands for “Not Recommended for New Designs.” While the product is currently in production, TDK advises against using it in new product developments, suggesting that newer or alternative components might be available or that the product may eventually be phased out. However, it remains available for existing designs and maintenance.
• Rated Voltage [DC] / V (16): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 16V rating makes this capacitor suitable for low-voltage digital and analog circuits, common in many commercial electronic devices.
• Lead Length / Package Type (5mm for Bulk): This indicates that the leads are 5mm long and the capacitors are supplied in bulk packaging. The 5mm lead length provides sufficient material for through-hole mounting and soldering, while bulk packaging is cost-effective for high-volume manufacturing.

Features and Benefits

• High Reliability and Stability: Manufactured by TDK, the FK18X5R1C105KN020 offers excellent long-term reliability and stable performance, crucial for maintaining circuit integrity over time.
• Wide Operating Temperature Range: The X5R dielectric characteristic ensures stable capacitance over a broad temperature range (-55°C to +85°C), making it suitable for diverse commercial environments.
• Compact and Robust Design: With its small physical dimensions (4mm L x 5.5mm W x 2.5mm T) and leaded package, it provides a robust solution for through-hole mounting, offering mechanical stability and ease of handling during assembly.
• Versatile Application Suitability: Its 1μF capacitance and 16V rating, combined with commercial-grade qualification, make it an ideal choice for a wide array of general-purpose filtering, decoupling, and timing applications.
• Cost-Effective for Volume Production: Supplied with 5mm leads in bulk packaging, this component is well-suited for efficient and economical integration into large-scale manufacturing processes.

Typical Applications
