FG18C0G1H681JNT00 FG18C0G1H681JNT00 Ceramic Capacitor (Leaded MLCC)

FG18C0G1H681JNT00 is a high-quality leaded ceramic capacitor manufactured by TDK, a global leader in electronic components. This passive component, specifically a multi-layer ceramic capacitor (MLCC), is designed for a wide array of commercial-grade applications where stability, reliability, and precision are paramount. Its C0G dielectric characteristic ensures extremely stable capacitance over temperature, making it an ideal choice for critical timing and filtering circuits. TDK’s commitment to innovation and quality is reflected in this component, which offers excellent electrical performance in a compact, through-hole package.

Key Specifications

The FG18C0G1H681JNT00 boasts several key specifications that define its performance and suitability for various designs:

• Capacitance: 680pF – This value indicates the component’s ability to store an electrical charge. A 680pF capacitance is suitable for high-frequency filtering, coupling, and decoupling applications where precise charge storage is required.
• Tolerance: ±5% – This specifies the permissible deviation from the nominal capacitance value. A ±5% tolerance is considered tight for a ceramic capacitor, ensuring consistent performance and making it suitable for applications that demand accuracy.
• Rated Voltage [DC]: 50V – This is the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown. A 50V rating provides ample headroom for many standard commercial and industrial power supply rails and signal processing circuits.
• Temp. Chara.: C0G – The C0G dielectric is renowned for its exceptional temperature stability. Capacitors with C0G characteristics exhibit negligible change in capacitance over a wide temperature range (-55°C to +125°C), making them ideal for precision applications where temperature variations could otherwise affect circuit performance.
• L(Max.) / W(Max.) / T(Max.): 4mm / 5.5mm / 2.5mm – These dimensions represent the maximum length, width, and thickness of the capacitor body. These compact dimensions allow for efficient use of PCB space, which is crucial in modern miniaturized electronic devices.
• F(Nom.): 2.5mm – This refers to the nominal lead spacing, which is the distance between the centers of the two leads. A 2.5mm lead spacing is a common standard for through-hole components, facilitating easy integration into standard PCB layouts.
• Lead Length / Package Type: 7mm for Bulk – The 7mm lead length provides sufficient length for manual insertion or automated assembly processes, ensuring secure soldering to the PCB. The bulk packaging is suitable for smaller production runs or prototyping needs.
• Product Status: Production (NRND) – This indicates that the component is currently in production but is ‘Not Recommended for New Designs’. While available for existing designs, engineers might consider newer alternatives for future projects.

Features and Benefits

• Exceptional Temperature Stability (C0G Dielectric): The C0G characteristic ensures that the capacitance remains virtually unchanged across a broad temperature range, making it perfect for precision timing, filtering, and resonant circuits that require stable performance regardless of environmental conditions.
• High Reliability and Long Lifespan: Manufactured by TDK, a leader in passive components, this capacitor is built to stringent quality standards, offering robust performance and extended operational life in demanding commercial applications.
• Halogen-Free Construction: Adherence to halogen-free standards demonstrates TDK’s commitment to environmental responsibility, making this component suitable for eco-conscious designs and meeting various international environmental regulations.
• Precise Capacitance Tolerance (±5%): The tight tolerance ensures that the actual capacitance is very close to the nominal value, which is critical for applications where exact frequency response or timing is essential, reducing the need for calibration.
• Compact and Versatile Design: With its small physical dimensions and standard lead spacing, the FG18C0G1H681JNT00 can be easily integrated into a wide range of through-hole designs, optimizing PCB layout and density.

Typical Applications

• Precision Timing Circuits: Due to its C0G dielectric and tight tolerance, this capacitor is ideal for use in oscillators, timers, and clock generation circuits where stable frequency and accurate timing are paramount, such as in microcontrollers and digital signal processors.
• High-Frequency Filtering and Decoupling: The 680pF capacitance and excellent frequency characteristics make it suitable for filtering unwanted noise in power supply lines and decoupling ICs in high-frequency applications, ensuring signal integrity and reducing electromagnetic interference (EMI).
• Analog Signal Processing: In audio amplifiers, sensors, and other analog circuits, the FG18C0G1H681JNT00 can be used for coupling, bypassing, and tone control, benefiting from its low distortion and stable performance.
• Medical and Industrial Instrumentation: The reliability and precision of this TDK capacitor make it a strong candidate for use in sensitive medical diagnostic equipment, industrial control systems, and test and measurement instruments where accuracy and consistent operation are critical.
• Automotive Electronics (Non-Safety Critical): While commercial grade, its robust construction and stable performance can find applications in non-safety-critical automotive systems, such as infotainment units, dashboard displays, and auxiliary control modules.
