The **CSEB1350-R93M** is a high-performance, surface-mount (SMD) molded power inductor. It is commonly used in DC-DC converters, voltage regulator modules (VRMs), and high-current power supplies where space and efficiency are critical. --- ### ## 1. Key Technical Specifications Based on the part number nomenclature (typically associated with manufacturers like Cyntec), here are the primary technical characteristics: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.93 µH | Measured at 100kHz, 1.0V | | **Tolerance** | ±20% (M) | Standard industry tolerance | | **Current Rating (Isat)** | ~30A - 40A | Saturation current depends on temperature rise | | **DC Resistance (DCR)** | ~1.5 mΩ - 2.5 mΩ | Ultra-low resistance to minimize power loss | | **Dimensions** | 13.5 x 12.5 x 5.0 mm | Standard 1350 package size | | **Operating Temp** | -40°C to +125°C | Automotive/Industrial grade range | --- ### ## 2. Core Features & Construction * **Molded Structure:** The inductor is constructed using a metallic powder core molded around the copper coil. This design provides excellent magnetic shielding and reduces "buzz" noise (acoustic noise). * **Soft Saturation:** Unlike ferrite cores that lose inductance sharply at high currents, the molded iron powder core exhibits a "soft" saturation curve, maintaining stability under heavy loads. * **High Efficiency:** The use of flat wire or heavy-gauge copper winding keeps the DCR extremely low, which reduces heat generation and improves battery life in portable devices. --- ### ## 3. Common Applications The CSEB1350-R93M is designed for high-density power electronics, including: 1. **Computing:** CPU/GPU core power supplies in servers and high-end workstations. 2. **Automotive:** Infotainment systems and Advanced Driver Assistance Systems (ADAS). 3. **Industrial:** High-current Point-of-Load (PoL) converters. 4. **Telecom:** Base station power modules. --- ### ## 4.
