The **CLT32-R15** is a high-performance power inductor, typically used in DC-DC converters and high-current power supply modules. It belongs to the **CLT series** (often manufactured by companies like Delta Electronics or Eaton/Coiltronics), known for its low profile and high efficiency. --- ## 1. Technical Specifications The "R15" in the part number signifies its inductance value. Below are the typical specifications for this component: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.15 µH (150 nH) | | **Tolerance** | ±20% | | **DCR (Direct Current Resistance)** | Very Low (typically < 0.5 mΩ) | | **Saturation Current ($I_{sat}$)** | High (often 40A - 60A+) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 3.2mm x 2.5mm (approx.) | --- ## 2. Key Features * **High Current Density:** Designed to handle massive amounts of current relative to its small physical footprint. * **Low Core Loss:** Utilizes advanced ferrite or metal powder materials to ensure minimal energy is wasted as heat during high-frequency switching. * **Magnetically Shielded:** The construction prevents electromagnetic interference (EMI) from leaking out and affecting surrounding sensitive components. * **SMD Design:** Surface Mount Device format, compatible with automated pick-and-place assembly. --- ## 3. Applications The CLT32-R15 is commonly found in modern high-power electronics where space is limited but power requirements are high: 1. **Voltage Regulator Modules (VRMs):** Used on motherboards and server cards to power CPUs and GPUs. 2. **Point-of-Load (POL) Converters:** Decentralized power conversion in telecommunications equipment. 3. **High-speed Networking:** Switches and routers requiring stable, high-current power rails. 4. **Mobile Devices:** High-end tablets or laptops where low-profile components are mandatory. --- ## 4. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually follows this logic: ```text CLT 32 - R15 | | | | | +-- Inductance Value (R15 = 0.15 microhenries) | +--------- Physical Size Code (3.2mm footprint class) +-------------- Series Name (Commonly Delta Electronics series) ```
