The **SSHB10H-R04760** is a high-performance, dual-mode common mode choke coil manufactured by **KEMET**. It is designed specifically for suppressing electromagnetic interference (EMI) in power supply circuits. --- ### 1. Key Technical Specifications | Parameter | Value / Specification | | :--- | :--- | | **Inductance (Min)** | 76.0 mH | | **Rated Current (AC)** | 0.4 A | | **DC Resistance (Max)** | 2.50 $\Omega$ | | **Temperature Rise (Max)** | 45 K | | **Operating Temperature** | -25°C to +120°C | | **Mounting Type** | Through-Hole (Vertical) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's construction: * **SSHB**: Series name (Hybrid Choke). * **10**: Core size/Series identification. * **H**: High-permeability material (typically 10,000 $\mu$). * **R04**: Rated current (0.4 Amperes). * **760**: Inductance value (76.0 mH). --- ### 3. Core Features and Technology The SSHB series is unique because it functions as a **Hybrid Choke**. It combines two suppression functions into a single component: 1. **Common Mode Noise Suppression**: High inductance effectively filters out noise traveling in the same direction on both lines. 2. **Differential Mode Noise Suppression**: Due to its magnetic structure, it also acts as a leakage inductance transformer to filter out noise occurring between the two lines. 3. **Advanced Material**: It utilizes a proprietary high-permeability ferrite core which allows for a high inductance value in a compact footprint. --- ### 4. Typical Applications This component is primarily used in power conversion stages where space is limited but high noise suppression is required: * **Switching Power Supplies (SMPS)**: Used in the AC input stage. * **LED Lighting**: To prevent flicker and EMI compliance issues. * **Home Appliances**: Ensuring compliance with EMC regulations (like CISPR or FCC). * **Industrial Automation**: Protecting sensitive control circuits from line noise. --- ### 5. Physical Configuration The "H" in the SSHB10H designation often refers to the **Vertical Type** orientation. This design is preferred for PCBs where horizontal surface area is limited but vertical clearance is available.
