The part number **107MDCL202KFH** refers to a high-performance **Multilayer Ceramic Capacitor (MLCC)**, typically used in industrial or automotive power electronics. This specific part is associated with manufacturers like **Holy Stone Enterprise** or similar specialty capacitor producers. Below is a detailed breakdown of the electronic specifications based on the alphanumeric code. --- ## 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 100 µF (Microfarads) | "107" = 10 followed by 7 zeros in pF | | **Voltage Rating** | 2000V (2kV) | "202" = 20 followed by 2 zeros in Volts | | **Tolerance** | ±10% | "K" stands for 10% tolerance | | **Dielectric** | X7R | Typical for the "MDCL" series (Stable temperature) | | **Package Size** | High Voltage Case | Usually a larger SMD footprint (e.g., 2220 or larger) | | **Termination** | Flexible / Standard | "FH" often denotes Lead-Free/RoHS compliant with specific finish | --- ## 2. Deciphering the Part Number The code can be broken down into functional segments: 1. **107**: The **Capacitance Value**. In picofarads (pF), 107 means $10 \times 10^7$ pF, which equals **100,000,000 pF** or **100 µF**. 2. **MDCL**: The **Series Code**. This indicates the manufacturer's specific product line, often standing for "Medium/High Voltage Dielectric Ceramic Layers." 3. **202**: The **Voltage Rating**. $20 \times 10^2$ Volts, resulting in **2000V DC**. 4. **K**: The **Tolerance**. Represents **±10%**. 5. **FH**: The **Packaging/Termination**. Indicates RoHS compliance, plating material (like Tin), and sometimes the reel size. --- ## 3. Key Applications Because this capacitor combines a very high capacitance (100µF) with an extremely high voltage rating (2kV), it is used in demanding environments: * **Power Inverters:** Used for DC-link smoothing in renewable energy systems. * **EV Charging:** High-voltage filtering in electric vehicle onboard chargers. * **Medical Equipment:** Snubber circuits in X-ray or MRI power supplies. * **Industrial Ballasts:** Surge protection and filtering in high-power lighting or motor drives. --- ## 4. Performance Characteristics ```cpp // Typical Thermal and Electrical Behavior Temperature_Range: -55°C to +125°C; Dielectric_Constant: High (X7R); Aging_Rate: ~2.5% per decade hour; Dissipation_Factor: Low (typically < 2.5%); ``` ### Safety Note When handling or designing with the **107MDCL202KFH**, ensure the PCB creepage distances are sufficient for **2000V** to prevent arcing. These capacitors can store significant energy; discharge them safely before handling. ---
