The Würth Elektronik 74479787247A is a power multilayer inductor from the WE-PMI series. It offers 4.7 µH inductance with ±20% tolerance, measured at 1 MHz and 5 mA. The component is designed for surface mount assembly in a 1008 package.
Key electrical characteristics include a rated current of 1 A for a temperature rise of 20 K and 1.5 A for 40 K rise. Saturation current is 270 mA typical. DC resistance is 110 mΩ ±25% with a maximum of 137.5 mΩ. Self-resonant frequency is at least 25 MHz, and Q-factor is minimum 32 at 1 MHz.
The operating temperature range is -40°C to +125°C. It is RoHS compliant, REACH conform, and halogen free. Moisture sensitivity level is MSL 1 (unlimited). The WE-PMI series is designed for power applications requiring low core losses and high current handling. The multilayer construction provides excellent EMI suppression and compact size.
