FK18C0G1H101JN020 FK18C0G1H101JN020 Ceramic Capacitor (Leaded MLCC)

FK18C0G1H101JN020 is a high-quality leaded ceramic capacitor manufactured by TDK, a global leader in electronic components. This specific component is a Multilayer Ceramic Capacitor (MLCC) designed for through-hole mounting, making it suitable for a wide range of commercial-grade electronic circuits. Its primary function is to store and release electrical energy, filter noise, and stabilize voltage, contributing to the overall performance and reliability of electronic devices. As a passive component, it plays a crucial role in signal coupling, decoupling, and timing applications, offering excellent stability and low loss characteristics due to its C0G dielectric.

Key Specifications

The capacitor’s ‘Apps.’ attribute specifies it as ‘Commercial Grade’, indicating its suitability for general electronic products and systems where standard performance and reliability are required, as opposed to specialized automotive or industrial applications. The ‘Brand’ is ‘TDK’, signifying a reputable manufacturer known for high-quality and reliable electronic components. The ‘Feature’ is ‘General’, further emphasizing its broad applicability across various circuit designs. A ‘Tolerance’ of ‘±5%’ means the actual capacitance value will be within 5% of the nominal value, which is a common and acceptable precision for many commercial applications, ensuring consistent circuit performance. The ‘Capacitance’ is ‘100pF’ (picofarads), a relatively small capacitance value typically used for high-frequency filtering, resonant circuits, or timing applications where precise, low-capacitance values are critical. The physical dimensions are detailed with ‘F(Nom.) / mm’ at ‘2.5’, referring to the nominal lead spacing, crucial for PCB layout and assembly. ‘L(Max.) / mm’ is ‘4’, ‘T(Max.) / mm’ is ‘2.5’, and ‘W(Max.) / mm’ is ‘5.5’, which are the maximum length, thickness, and width of the capacitor body, respectively, ensuring proper fit and clearance in circuit designs. The ‘Temp. Chara.’ is ‘C0G’, which is a highly stable dielectric material known for its excellent temperature stability, meaning its capacitance changes very little over a wide temperature range, making it ideal for precision applications. The ‘Component Type’ is ‘Ceramic Capacitor (Leaded MLCC)’, clearly defining its construction and mounting style. ‘Product Status’ is ‘Production(NRND)’, indicating that it is currently in production but is ‘Not Recommended for New Designs’, suggesting that while available, newer alternatives might exist or be preferred for future projects. The ‘Rated Voltage [DC] / V’ is ’50’, meaning it can safely operate in circuits with a maximum DC voltage of 50 volts, which is common for many low-power and signal processing applications. Finally, ‘Lead Length / Package Type’ is ‘5mm for Bulk’, specifying the length of the leads and that it is supplied in bulk packaging, suitable for manual or automated assembly processes.
