This leaded Multi-Layer Ceramic Capacitor (MLCC) is designed for commercial-grade applications, offering stable performance and reliability. As a passive component, its primary function is to store and release electrical energy, filter noise, and stabilize voltage in electronic circuits. The C0G temperature characteristic ensures exceptional stability over a wide temperature range, making it an ideal choice for precision applications where capacitance drift must be minimized.

Key Specifications

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

Applications (Commercial Grade): This designation indicates that the capacitor is designed and tested to meet the rigorous demands of general commercial electronic products. It signifies a balance of performance, reliability, and cost-effectiveness for a broad range of non-critical industrial and consumer applications.

Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Specifying TDK ensures a product from a trusted manufacturer with a strong reputation for engineering excellence and reliability.

Feature (Mid): While ‘Mid’ can be a general descriptor, in the context of ceramic capacitors, it often refers to a standard or general-purpose feature set, offering a good balance of performance without specialized high-end characteristics, suitable for a wide array of common circuit designs.

Tolerance (±5%): This indicates the permissible deviation of the actual capacitance value from its nominal value. A ±5% tolerance is considered a tight tolerance for ceramic capacitors, signifying higher precision and making it suitable for applications where accurate timing or frequency response is crucial.

Capacitance (180pF): This is the fundamental electrical property of the capacitor, representing its ability to store charge. A capacitance of 180 picofarads is typical for high-frequency filtering, coupling, or timing applications in various electronic circuits.

F(Nom.) / mm (5mm): This likely refers to the nominal lead spacing or body length, indicating the physical dimensions relevant for PCB layout and assembly. A 5mm dimension helps engineers plan the component placement accurately.

L(Max.) / mm (4mm), T(Max.) / mm (2.5mm), W(Max.) / mm (5.5mm): These are the maximum length, thickness, and width of the capacitor body, respectively. These physical dimensions are crucial for mechanical design, ensuring the component fits within the allocated space on a printed circuit board (PCB) and for automated assembly processes.

Temp. Chara. (C0G): The C0G (or NP0) temperature characteristic is highly desirable. It signifies a very stable dielectric material with negligible change in capacitance over a wide temperature range (-55°C to +125°C). This makes the FK28C0G2E181JN000 ideal for precision applications where temperature stability is paramount.

Component Type (Ceramic Capacitor (Leaded MLCC)): This clarifies that it is a ceramic capacitor, specifically a Multi-Layer Ceramic Capacitor (MLCC) with leads, distinguishing it from surface-mount (SMD) versions. Leaded components are often preferred for prototyping, manual assembly, or applications requiring specific mechanical stability.

Product Status (Production(NRND)): ‘Production (NRND)’ means the product is currently in production but is ‘Not Recommended for New Designs.’ While available for existing designs, engineers should consider newer alternatives for future projects, though it remains fully supported for current users.

Rated Voltage [DC] / V (250V): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 250V rating provides a substantial voltage margin for many common electronic circuits.

Lead Length / Package Type (7mm for Bulk): This specifies the length of the leads, which are 7mm when supplied in bulk packaging. This information is vital for manufacturing processes, ensuring compatibility with automated insertion equipment or for manual soldering.

Features and Benefits
