The **HPC073N-R22MTR** is a high-performance, surface-mount (SMD) power inductor. It is commonly used in DC-DC converters, voltage regulator modules (VRMs), and high-current power supplies for telecommunications and computing hardware. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.22 µH | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~0.90 mΩ (Typical) | | **Saturation Current (Isat)** | ~40.0 A to 50.0 A | | **Heat Rating Current (Irms)** | ~25.0 A to 30.0 A | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | Approx. 7.4 x 6.6 x 3.0 mm | --- ### ## Key Features 1. **Low Profile Design:** The "073" series typically signifies a compact footprint (7x7mm class) with a low height, making it ideal for thin electronic assemblies. 2. **Molded Construction:** These inductors usually feature a metal powder molding technology. This provides a magnetic shield, reducing Electromagnetic Interference (EMI) and preventing audible "buzzing." 3. **High Saturation:** Because it uses a metal alloy core, it handles high current peaks without the inductance dropping sharply (soft saturation). 4. **Low DCR:** The extremely low DC resistance minimizes power loss due to heat, significantly increasing the efficiency of power stages. --- ### ## Applications The HPC073N-R22MTR is designed for high-density power environments, including: * **CPU/GPU Power Supply:** Used in multi-phase buck converters for processors. * **Networking Gear:** High-current power rails in switches and routers. * **Laptops/Tablets:** Power management units where space is limited but current demand is high. --- ### ## Part Number Breakdown While naming conventions can vary slightly by manufacturer (often associated with brands like **Taiyo Yuden** or similar high-end magnetics producers), the logic usually follows: * **HPC:** Series Code (High Power/Current). * **073:** Dimensions (Approx 7mm x 7mm footprint, 3mm height). * **R22:** Inductance Value (R22 = 0.22 µH). * **M:** Tolerance (M = ±20%). * **TR:** Packaging (Tape and Reel).
