The **SS26V-R080470** is a high-performance, common mode choke coil designed primarily for noise suppression in power supply circuits. It is manufactured by KEMET (formerly Tokin). --- ### 1. Key Technical Specifications | Parameter | Value / Detail | | :--- | :--- | | **Series** | SS26V (High Permeability Core) | | **Inductance (Min)** | 47 mH | | **Rated Current (AC)** | 0.8 A | | **Rated Voltage** | 250 VAC / 300 VDC | | **DC Resistance (Max)** | 0.95 Ω per line | | **Operating Temperature** | -25°C to +120°C | | **Mounting Type** | Through-hole (Vertical) | --- ### 2. Physical Characteristics The part belongs to the **SS26V** family, which features a vertical orientation to save PCB real estate. * **Core Material:** Ferrite (High permeability). * **Structure:** Dual-winding on a single core. * **Dimensions:** Approximately 23mm x 19mm x 26mm (Width x Depth x Height). * **Lead Spacing:** Standardized for easy PCB insertion. --- ### 3. Functional Purpose The primary role of the SS26V-R080470 is **Common Mode Noise Filtering**. * **Common Mode Rejection:** It allows differential currents (the actual power needed for your device) to pass through with minimal resistance, while creating high impedance for common-mode noise (unwanted interference affecting both lines simultaneously). * **EMI Compliance:** It helps electronic devices meet electromagnetic interference (EMI) standards like FCC or CISPR by preventing noise from traveling back into the AC power lines. --- ### 4. Typical Applications Commonly found in the input stage of: 1. **Switch Mode Power Supplies (SMPS):** Used in chargers, PC power units, and LED drivers. 2. **Audio-Visual Equipment:** To prevent line noise from affecting sound or picture quality. 3. **Office Automation:** Printers, scanners, and copiers. 4. **Industrial Controllers:** Protecting sensitive logic circuits from industrial grid noise. --- ### 5. Part Number Breakdown * **SS26V:** Series name (Vertical type, large size). * **R08:** Rated current indicator (0.8 Amperes). * **0470:** Inductance value code (470 x 100 µH = 47,000 µH or 47 mH).
