The **CSCM1480H-R30M** is a high-performance, high-current power inductor typically used in automotive and industrial power electronics. It belongs to a class of surface-mount (SMD) power inductors designed for DC-DC converters and voltage regulator modules (VRMs). --- ### 1. Key Technical Specifications Based on the part number nomenclature, here are the primary electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Inductance** | 0.30 µH | The "R30" indicates 0.30 microhenries. | | **Tolerance** | ±20% | Standard tolerance for high-current inductors. | | **DCR (Resistance)** | ~0.5 - 0.9 mΩ | Ultra-low DC resistance to minimize power loss. | | **Saturation Current** | ~50A - 70A | The point where inductance drops by 30%. | | **Operating Temp** | -55°C to +125°C | Designed for harsh environments. | | **Package Size** | 14.0 x 13.0 mm | "1480" refers to the physical footprint. | --- ### 2. Construction and Composition The CSCM series utilizes specific materials to achieve high efficiency: * **Composite Core:** Usually made from a metal alloy powder. Unlike traditional ferrite cores, these offer "soft saturation," meaning the inductance drops gradually rather than sharply when current increases. * **Shielded Design:** The molded construction provides magnetic shielding, which significantly reduces Electromagnetic Interference (EMI) with surrounding components. * **Flat Wire Technology:** Many inductors in this class use flat copper wire instead of round wire. This increases the surface area, reducing the "Skin Effect" and lowering the DCR. --- ### 3. Applications The CSCM1480H-R30M is specifically engineered for high-power density applications: 1. **Automotive Electronics:** Power supplies for Advanced Driver Assistance Systems (ADAS) and Infotainment. 2. **GPU/CPU Power:** High-phase count VRMs (Voltage Regulator Modules) for servers and high-end computing. 3. **DC/DC Converters:** Point-of-Load (POL) converters where high efficiency and low heat generation are critical. --- ### 4. Part Number Breakdown Understanding the code helps in identifying replacements or alternatives: * **CSCM:** Series name (typically Molded Power Inductor). * **1480:** Dimensions (approx. 14mm length/width, 8.0mm height). * **H:** High-current or Automotive grade designation. * **R30:** Inductance value (R = decimal point; 0.30 µH). * **M:** Tolerance (M = ±20%). ---
