### SS30V-R080960: Technical Overview The **SS30V-R080960** is a high-performance **Common Mode Choke Coil** (EMI Suppression Filter) manufactured by **KEMET** (formerly NEC TOKIN). It is specifically designed to suppress electromagnetic interference (EMI) in power supply circuits. --- ### 1. Key Technical Specifications The model number encodes specific electrical characteristics. Below are the primary specifications for this component: | Parameter | Specification | | :--- | :--- | | **Rated Voltage** | 250 VAC / VDC | | **Rated Current** | 0.8 Amperes | | **Inductance (Min)** | 96.0 mH | | **DC Resistance (Max)** | 1.10 Ω per line | | **Operating Temperature** | -25°C to +120°C | | **Core Material** | Manganese-Zinc (Mn-Zn) Ferrite | | **Mounting Type** | Through-Hole (Vertical Type) | --- ### 2. Functional Description The SS30V series is a **Common Mode Choke**. Its primary functions include: * **Noise Suppression:** It provides high impedance against common-mode noise (noise flowing in the same direction on both lines) while allowing the differential-mode power current to pass with minimal resistance. * **High Inductance:** At 96 mH, this specific model is designed for low-frequency noise suppression, making it highly effective for power line filtering. * **Compact Vertical Design:** The "V" in the series name denotes a vertical orientation, which helps save PCB (Printed Circuit Board) real estate. --- ### 3. Construction and Materials * **Core:** High-permeability Mn-Zn ferrite core allows for high inductance in a relatively small package. * **Winding:** Two separate coils wound on a single core. The magnetic fields generated by the supply current cancel each other out, while the magnetic fields from noise add up and are dissipated. * **Bobbin:** High-temperature resistant plastic to ensure safety and insulation between windings. --- ### 4. Common Applications This component is typically found in the input stage of power electronics to comply with EMI/EMC regulations (such as FCC or CISPR): 1. **Switching Power Supplies (SMPS):** Filtering switching noise from reaching the AC mains. 2. **Audio-Visual Equipment:** Protecting sensitive analog circuits from digital high-frequency interference. 3. **Office Automation:** Used in printers, copiers, and computers. 4. **Industrial Controllers:** Ensuring stable operation in electrically "noisy" environments. ---
