Additional Details

The MHCC12050-R47M-R7 has an inductance value of 0.47 µH (R47M indicates 0.47µH with M as the tolerance code, usually ±20%). The dimensions are approximately 12.5mm x 12.5mm x 5.0mm. The saturation current is a key parameter and can range from several amps to over ten amps, but the datasheet should be consulted for the exact value. The DC resistance (DCR) is usually very low, often in the range of milliohms, contributing to high efficiency. The operating temperature range is typically from -40°C to +125°C or higher. This inductor is a surface mount device (SMD) and should be reflow soldered according to the manufacturer's recommended profile. Refer to the manufacturer's datasheet for detailed specifications, including inductance tolerance, Q factor, self-resonant frequency, and Irms (RMS current). Proper PCB layout is crucial for optimal performance; guidelines are provided in the application notes. Ensure that the saturation current is not exceeded in the application to avoid inductance roll-off and performance degradation. The “-R7” suffix typically indicates the packaging type (e.g., tape and reel).
