Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Impedance (at 100 MHz)** | 600 $\Omega$ (±25%) | | **Rated Current (Max)** | 2.0 A | | **DC Resistance (Max)** | 0.07 $\Omega$ | | **Operating Temperature** | -55°C to +125°C | | **Package Size (Metric)** | 2012 (2.0mm x 1.25mm) | | **Package Size (Inch)** | 0805 | | **Height** | 0.85 mm | --- ### 2. Functional Characteristics #### Noise Suppression Mechanism The MPZ series works by increasing its impedance at high frequencies. It acts as a resistor for high-frequency noise, converting that noise energy into heat, while allowing low-frequency DC signals to pass through with minimal loss. #### Material Type (S Material) The "S" in the part number indicates a standard frequency characteristic. It provides high impedance across a broad range, making it versatile for general noise applications. #### Power Line Optimization Unlike signal-line beads, this component is optimized for **Power Lines**: * **High Current Rating:** Can handle up to 2.0A without saturating or overheating. * **Low DC Resistance (Rdc):** Minimizes voltage drops across the component. --- ### 3.
