The **PCMC063T-R56MN** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converters and voltage regulator modules. It belongs to the **PCMC series** manufactured by companies like Susumu or Cyntec. --- ### ## Technical Specifications The part number follows a specific nomenclature that defines its electrical and physical characteristics: | Parameter | Value | Description | | :--- | :--- | :--- | | **Inductance** | 0.56 µH | The nominal inductance value (R56). | | **Tolerance** | ±20% | Indicated by the "M" suffix. | | **Case Size** | 063 | Approximately 7.3 x 6.6 mm footprint. | | **DCR (Max)** | ~3.3 - 3.6 mΩ | DC Resistance; determines power loss. | | **Heat Rating Current** | ~14 - 16 A | Current causing a 40°C temperature rise. | | **Saturation Current** | ~22 - 25 A | Current at which inductance drops by 20-30%. | | **Operating Temp** | -55°C to +125°C | Standard industrial range. | --- ### ## Key Features 1. **Metal Alloy Core:** Unlike traditional ferrite inductors, these use a molded metal powder core. This allows for higher saturation currents and a "soft" saturation characteristic (it doesn't drop to zero inductance instantly). 2. **Shielded Construction:** The molded design inherently provides magnetic shielding, reducing Electromagnetic Interference (EMI) with surrounding components. 3. **High Efficiency:** The extremely low DC Resistance (DCR) minimizes copper losses, making it ideal for high-efficiency power supplies. 4. **Compact Profile:** The "T" in the part number usually indicates a specific height profile (typically around 3.0 mm), saving vertical space on PCBs. --- ### ## Common Applications This inductor is typically found in high-current, low-voltage power stages: * **CPU/GPU Power:** Voltage Regulator Modules (VRMs) for processors. * **Telecom:** High-density power distribution units. * **Infotainment:** Automotive electronic control units. * **Mobile Devices:** Battery-powered devices requiring efficient buck converters. --- ### ## Schematic Symbol Representation In a circuit diagram, it is represented as a standard inductor with two terminals: ```text L1 ---( ( (--- 0.56uH ```
