Key Specifications

The FG18C0G1H680JNT00 boasts several key specifications that define its performance and suitability for various designs:

• Capacitance: 68pF – This value indicates the component’s ability to store electrical charge. A 68pF capacitance is typically used in high-frequency applications, resonant circuits, and filtering where small, precise capacitance is required.
• Tolerance: ±5% – This specifies the permissible deviation from the nominal capacitance value. A ±5% tolerance is considered precise, ensuring that the actual capacitance falls within a narrow range, which is critical for applications requiring stable and predictable circuit behavior.
• Temp. Chara.: C0G – The C0G dielectric is known for its exceptional temperature stability. It exhibits negligible change in capacitance over a wide temperature range (-55°C to +125°C) and very low dissipation factor, making it ideal for precision timing, filtering, and resonant circuits where temperature-induced drift is unacceptable.
• Rated Voltage [DC]: 50V – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 50V rating makes this capacitor suitable for a broad spectrum of low to medium voltage applications in commercial electronics.
• Dimensions: L(Max.) / 4mm, W(Max.) / 5.5mm, T(Max.) / 2.5mm – These maximum physical dimensions indicate the compact size of the component, allowing for integration into space-constrained designs. The small footprint is advantageous for miniaturization in modern electronic devices.
• Lead Length / Package Type: 7mm for Bulk – The 7mm lead length provides flexibility for through-hole mounting and manual assembly, especially in prototyping or lower-volume production. Bulk packaging is efficient for various production scales.
• Apps.: Commercial Grade – This designation signifies that the capacitor is designed and tested to meet the reliability and performance requirements typical of commercial electronic products, ensuring robust operation in standard environments.
• Feature: General, Halogen-free – Being halogen-free indicates compliance with environmental regulations, making it a more eco-friendly choice. The ‘General’ feature highlights its versatility for a wide array of common circuit functions.
