### SD6030-2R7-R Component Overview The **SD6030-2R7-R** is a high-performance, low-profile, shielded surface-mount (SMD) power inductor. It is part of the SD6030 series, commonly manufactured by Eaton (formerly Cooper Bussmann/Coiltronics). These inductors are designed for applications where space is limited and electromagnetic interference (EMI) must be minimized. --- ### Key Specifications | Parameter | Value | | :--- | :--- | | **Inductance** | 2.7 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 3.55 Amps | | **Saturation Current (Isat)** | 3.20 Amps | | **DC Resistance (DCR)** | 27.3 mΩ (Max) | | **Operating Temperature** | -40°C to +125°C | | **Dimensions (LxWxH)** | 6.0mm x 6.0mm x 3.0mm | | **Shielding** | Magnetically Shielded | --- ### Technical Features and Construction 1. **Magnetic Shielding**: The "shielded" design ensures that the magnetic flux is contained within the component. This reduces EMI, making it ideal for high-density boards near sensitive components like microprocessors or RF modules. 2. **Ferrite Core**: It utilizes a ferrite drum core with a ring sleeve, providing high efficiency and low core losses at high frequencies. 3. **Low Profile**: With a height of only 3.0mm, it is suitable for thin electronic devices like tablets, SSDs, and handheld instruments. 4. **Isat vs. Irms**: * **Irms (3.55A)**: The current that causes a 40°C temperature rise. * **Isat (3.20A)**: The current at which the inductance drops by approximately 30% due to core saturation. --- ### Common Applications * **DC-DC Converters**: Used in buck, boost, and SEPIC topologies for voltage regulation. * **Battery Powered Equipment**: High efficiency helps prolong battery life in portable electronics. * **Computing**: Powering chipsets, GPUs, and local rails on motherboards. * **Consumer Electronics**: Digital cameras, MP3 players, and LED driver circuits. --- ### Example Circuit Integration In a typical Buck Converter circuit, the inductor is placed after the switching transistors to smooth the output current: ```markdown [Input Voltage] --> [Switching MOSFETs] --> [SD6030-2R7-R] --> [Output Capacitor] --> [Vout] ```
