### Electronic Specifications: SRP2010TMA-R33M The **SRP2010TMA-R33M** is a high-current, shielded power inductor manufactured by Bourns. It is designed primarily for automotive and high-reliability industrial applications where miniaturization and high performance are required. --- ### Technical Specifications Table | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.33 µH | | **Tolerance** | ±20% | | **Inductance Frequency** | 1 MHz / 1 V | | **DCR (DC Resistance)** | 11.5 mΩ (Typ) / 14 mΩ (Max) | | **Irms (Heating Current)** | 6.5 A | | **Isat (Saturation Current)** | 9.0 A | | **Operating Temperature** | -55 °C to +150 °C | | **Package Size** | 2010 (2.0mm x 1.6mm x 1.0mm) | --- ### Key Electronic Characteristics 1. **Metal Alloy Powder Core:** Unlike traditional ferrite inductors, this part uses a metal alloy core. This construction allows for a **soft saturation** characteristic, meaning the inductance drops gradually as current increases rather than dropping sharply. 2. **Magnetic Shielding:** The inductor is fully shielded. This minimizes Electromagnetic Interference (EMI), which is critical in dense PCB layouts and sensitive automotive electronics. 3. **AEC-Q200 Compliance:** The "TMA" suffix indicates that this part is automotive grade. It has undergone rigorous stress testing for thermal shock, humidity resistance, and mechanical vibration. 4. **Flat Wire Construction:** The internal design uses flat wire technology, which lowers the **DC Resistance (DCR)**. Low DCR is essential for reducing power loss and preventing overheating in high-current paths. --- ### Application Usage This part is commonly used in DC-DC converters for: * **ADAS** (Advanced Driver Assistance Systems) * **Infotainment** systems * **LED lighting** modules * **Smartphones** and ultra-thin portable electronics ---
