The **SRN2012-R24M** is a high-performance, semi-shielded power inductor manufactured by Bourns. It is part of the SRN2012 series, designed for compact electronic devices requiring efficient power conversion. --- ### 1. Technical Specifications Below are the key electrical characteristics of the SRN2012-R24M: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±20% | | **Case Size (Metric)** | 2012 (2.0 mm x 1.2 mm) | | **Case Height** | 1.0 mm (Low Profile) | | **DC Resistance (DCR)** | 0.021 Ohms (Max) | | **Saturation Current (Isat)** | 4.5 A | | **Heating Current (Irms)** | 3.5 A | | **Operating Temperature** | -40 °C to +125 °C | --- ### 2. Key Features * **Semi-Shielded Construction:** It uses a magnetic epoxy coating. This offers a balance between the low cost of unshielded inductors and the low EMI (Electromagnetic Interference) of fully shielded inductors. * **High Current Density:** Despite its small footprint (2.0 x 1.2 mm), it can handle a saturation current of up to 4.5 Amps, making it ideal for high-efficiency power stages. * **Low Profile:** With a maximum height of 1.0 mm, it is suitable for ultra-thin consumer electronics like smartphones and tablets. --- ### 3.
