Key Specifications

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

• Apps. (Application Grade): Commercial Grade – This designation indicates that the capacitor is designed and tested to meet the rigorous demands of general commercial electronic products. It offers a balance of performance, reliability, and cost-effectiveness for a broad spectrum of non-automotive or non-military applications.
• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, magnetic products, and other electronic devices. Their brand signifies reliability, innovation, and adherence to stringent manufacturing standards.
• Feature: General – This indicates that the capacitor is a standard, general-purpose component suitable for a wide variety of circuit functions without specialized characteristics for extremely niche applications.
• Tolerance: ±5% – The capacitance value of 12pF is guaranteed to be within ±5% of its nominal value. This tight tolerance is crucial for applications requiring precise timing, filtering, or resonant frequency tuning, ensuring consistent circuit performance.
• Capacitance: 12pF – This is the nominal electrical capacitance of the component, meaning it can store 12 picofarads of charge per volt. This relatively small capacitance value is typically used in high-frequency circuits, oscillators, RF applications, and timing circuits.
• F(Nom.) / mm (Nominal Lead Pitch): 2.5mm – This refers to the standard distance between the centers of the two leads. A 2.5mm lead pitch is a common standard for through-hole components, ensuring compatibility with standard PCBs and prototyping boards.
• L(Max.) / mm (Maximum Length): 4mm – The maximum physical length of the capacitor body, excluding the leads. This dimension is critical for PCB layout and ensuring the component fits within the available physical space.
• T(Max.) / mm (Maximum Thickness): 2.5mm – The maximum physical thickness or height of the capacitor body. This dimension is important for vertical clearance in densely packed electronic enclosures.
• Temp. Chara. (Temperature Characteristic): C0G – C0G is one of the most stable dielectric materials for ceramic capacitors. It exhibits negligible change in capacitance over a wide temperature range (typically -55°C to +125°C) and very low dissipation factor, making it ideal for precision applications where temperature stability is paramount.
• W(Max.) / mm (Maximum Width): 5.5mm – The maximum physical width of the capacitor body. Along with length and thickness, this defines the overall footprint and spatial requirements of the component on a PCB.
• Component Type: Ceramic Capacitor (Leaded MLCC) – This specifies the fundamental type of capacitor. It’s a Multi-Layer Ceramic Capacitor (MLCC) that has been fitted with leads for through-hole mounting, combining the benefits of ceramic dielectric with traditional assembly methods.
• Product Status: Production (NRND) – “Not Recommended for New Designs” (NRND) indicates that while the product is still in production and available for existing designs, it is not advised for new product development. This might be due to newer, more efficient alternatives being available, or the product nearing end-of-life in the distant future.
• Rated Voltage [DC] / V: 50V – This is the maximum DC voltage that can be continuously applied across the capacitor without risking damage or premature failure. Operating within this voltage rating is crucial for component longevity and circuit reliability.
• Lead Length / Package Type: 5mm for Bulk – The leads are approximately 5mm long, and the component is supplied in bulk packaging, which is common for through-hole parts and suitable for manual or automated insertion processes.

Features and Benefits

• Exceptional Temperature Stability (C0G Dielectric): The C0G temperature characteristic ensures that the 12pF capacitance remains highly stable across a wide operating temperature range, minimizing drift and maintaining circuit precision in varying environmental conditions.
• High Precision and Reliability (±5% Tolerance): With a tight ±5% capacitance tolerance, the FK18C0G1H120JN020 offers consistent performance, critical for applications like timing circuits, filters, and resonant circuits where exact capacitance values are essential.
• Robust Through-Hole Design: The leaded package provides superior mechanical strength and vibration resistance compared to surface-mount components, making it suitable for applications exposed to physical stress or requiring manual assembly and repair.
• Reputable TDK Quality: Manufactured by TDK, this capacitor benefits from stringent quality control and advanced material science, ensuring long-term reliability and performance in commercial-grade electronic devices.
• Versatile Commercial Grade Application: Designed for general commercial use, this capacitor is a cost-effective yet reliable solution for a broad spectrum of electronic products, from consumer electronics to industrial control systems.

Typical Applications

The FK18C0G1H120JN020 ceramic capacitor finds its utility in numerous electronic applications due to its stable characteristics and precise capacitance:

• RF and High-Frequency Circuits: Its low capacitance (12pF) and C0G dielectric make it ideal for impedance matching, coupling, and decoupling in radio frequency (RF) circuits, oscillators, and tuners where stable performance at high frequencies is paramount.
• Precision Timing and Oscillator Circuits: The excellent temperature stability and tight tolerance are critical for crystal oscillators, RC oscillators, and other timing circuits where even small capacitance variations can significantly impact frequency accuracy and stability.
• Analog Signal Filtering: Used in passive filter networks (e.g., high-pass, low-pass, band-pass filters) for analog signals, particularly in audio equipment, sensor interfaces, and instrumentation, where precise frequency cutoff and minimal signal distortion are required.
• Voltage Reference and Sample-and-Hold Circuits: In precision voltage reference circuits or sample-and-hold amplifiers, this capacitor can be used for charge storage or as part of feedback networks, benefiting from its stability and low leakage.
• General Purpose Decoupling/Bypassing: While typically higher capacitance values are used for bulk decoupling, a 12pF capacitor can be effectively used for high-frequency noise bypassing very close to IC pins, especially in mixed-signal designs, to filter out high-frequency transients.

In summary, the FK18C0G1H120JN020 from TDK is a reliable and precise 12pF leaded ceramic capacitor with C0G dielectric, suitable for a wide range of commercial applications demanding high stability and accuracy.
