Technical Specification Breakdown The alphanumeric string follows KEMET’s standardized nomenclature. Here is the breakdown of each segment: | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | C326 | Goldmax 300 Series (Radial Leaded, Case Size 326) | | **Capacitance** | 111 | 110 pF (11 followed by 1 zero) | | **Tolerance** | F | ±1% (High Precision) | | **Voltage** | A | 250 Volts | | **Dielectric** | G | C0G (NP0) - Ultra-stable, non-sensitive to temp/voltage | | **Design** | 5 | Multilayer | | **Termination** | T | 100% Matte Tin (Sn) | | **Failure Rate** | A | Not Applicable / Standard | | **Packaging** | 7301 | Taped and Reeled (Ammo Pack or Reel) | --- ## 2. Key Component Features ### Dielectric Material: C0G (NP0) The use of **C0G** dielectric is the most significant feature. * **Stability:** Capacitance does not change with respect to time or voltage. * **Temperature Coefficient:** 0 ±30 ppm/°C from −55°C to +125°C. * **Low Loss:** Ideal for resonant circuits and high-frequency applications. ### Physical Form Factor * **Radial Leaded:** This is a "through-hole" component. It has two wires (leads) extending from the bottom, meant to be inserted into holes in a PCB. * **Conformal Coating:** The capacitor body is dipped in a gold-colored epoxy resin for environmental protection and insulation. --- ## 3. Applications Due to its high precision (±1%) and high voltage rating (250V), this part is typically used in: * **Critical Timing Circuits:** Where frequency stability is essential. * **Filtering & Matching:** In RF (Radio Frequency) or wireless communication equipment. * **Decoupling:** In high-voltage power supply lines where low ESR (Equivalent Series Resistance) is required. * **Industrial Controls:** Environments where mechanical stress might crack a standard surface-mount (SMD) capacitor. ---
