## SS30V-R200132: Technical Overview The **SS30V-R200132** is a high-performance **Common Mode Choke Coil** manufactured by KEMET (formerly NEC TOKIN). It is specifically designed for noise suppression in AC power lines, utilizing a high-permeability ferrite core to filter out electromagnetic interference (EMI). --- ### 1. Key Technical Specifications | Parameter | Value / Specification | | :--- | :--- | | **Rated Voltage** | 250 VAC / VDC | | **Rated Current** | 2.0 Amperes | | **Inductance (Min)** | 13.2 mH | | **DC Resistance (Max)** | 0.190 $\Omega$ | | **Temperature Rise** | 45 K (Max) | | **Operating Temp Range** | -25°C to +120°C | | **Terminal Type** | Through-hole (PCB Mount) | --- ### 2. Physical Characteristics * **Core Material:** Mn-Zn (Manganese-Zinc) Ferrite, known for high magnetic permeability and effective low-frequency noise suppression. * **Structure:** Vertical orientation to save PCB real estate. * **Construction:** Two separate windings on a single core that create opposing magnetic fields for common-mode signals, effectively canceling them out. --- ### 3. Functional Working Principle The SS30V-R200132 acts as an inductor for common-mode currents (interference traveling in the same direction on both lines) while allowing differential-mode currents (the actual power signal) to pass with minimal resistance. 1. **Common-Mode Filtering:** High impedance is presented to noise, preventing it from entering the device or leaking back into the power grid. 2. **Differential-Mode Low Impedance:** The magnetic flux cancels out for the supply current, ensuring efficient power delivery. --- ### 4. Common Applications * **Switching Power Supplies (SMPS):** Used at the input stage to meet EMI/EMC compliance. * **Consumer Electronics:** Televisions, audio equipment, and white goods. * **Industrial Equipment:** Protecting sensitive control circuits from noisy AC lines. * **Office Automation:** Printers and photocopiers. --- ### 5. Part Number Breakdown While KEMET coding varies, the SS30V series generally follows this logic: * **SS:** Series Name (Standard type). * **30V:** Physical size and Vertical orientation. * **R20:** Rated current (2.0 Amps). * **0132:** Nominal inductance (13.2 mH).
