The **DM05CE100DO3-SA-R02** is a specialized electronic component, specifically a **High-Frequency Multilayer Ceramic Capacitor (MLCC)** manufactured by **Kyocera (AVX)**. It is primarily used in RF (Radio Frequency) and microwave applications where low loss and high stability are critical. --- ### ## Technical Specifications Below are the primary parameters for this specific part number: | Parameter | Value / Specification | | :--- | :--- | | **Component Type** | Multilayer Ceramic Capacitor (MLCC) | | **Capacitance** | 10 pF (Picofarads) | | **Tolerance** | ±0.5 pF (indicated by 'D') | | **Voltage Rating** | 50V DC | | **Dielectric Material** | C0G (NP0) - Ultra Stable | | **Package / Case** | 0402 (EIA) / 1005 (Metric) | | **Termination** | Silver/Nickel/Tin (RoHS Compliant) | | **Operating Temp** | -55°C to +125°C | --- ### ## Detailed Breakdown of Features ### 1. Dielectric Performance (C0G/NP0) The "CE" in the part number indicates a **C0G** dielectric. This is a Class I material, meaning it is highly stable. * **Zero Drift:** The capacitance does not change significantly with temperature, frequency, or time. * **Low Loss:** It has a very low dissipation factor, making it ideal for high-Q circuits. ### 2. Physical Dimensions (0402) The "05" in the prefix typically refers to the physical size in specific manufacturer codes, corresponding to the **0402** inch standard (1.0mm x 0.5mm). This small footprint is essential for high-density PCB designs like smartphones and RF modules. ### 3. Application Use Cases Due to its 10pF value and high stability, this part is commonly found in: * **RF Matching Networks:** Tuning antennas for Bluetooth, Wi-Fi, or cellular signals. * **Filter Circuits:** Band-pass or low-pass filters where precise capacitance is required to maintain the cutoff frequency. * **Oscillators:** Providing stable timing for clock signals. --- ### ## Part Number Nomenclature (Typical Kyocera/AVX) | Code Segment | Meaning | | :--- | :--- | | **DM05** | Series/Size Designation (RF High-Q Series) | | **CE** | Dielectric Characteristic (C0G/NP0) | | **100** | Capacitance Code (10 x 10^0 = 10pF) | | **D** | Tolerance (±0.5 pF) | | **O3** | Voltage Rating (50V) | | **SA-R02** | Packaging / Termination / Internal Control Code |
