74456047 Description

Short technical summary and product information.

The Würth Elektronik 74456047 is a fixed inductor from the WE-PD4 series, featuring a drum core and wirewound construction with a ferrite core. It is unshielded and designed for surface-mount applications.

 

Key electrical specifications include an inductance of 4.7 µH at 100 kHz/100 mV with a tolerance of ±20%. The rated current is 5 A (ΔT = 40 K), and the saturation current is 6 A typical (|ΔL/L| < 10%). The DC resistance is 0.015 Ω typical and 0.019 Ω maximum at 20 °C. The self-resonant frequency is 38 MHz typical, and the maximum operating voltage is 120 V DC.

 

The inductor operates over a temperature range of -40 °C to +125 °C, with an ambient temperature range for rated current of -40 °C to +85 °C. It is RoHS3 compliant, REACH unaffected, and halogen free.

 

The component is packaged in a nonstandard surface-mount package with dimensions of 12.70 mm length, 10.00 mm width, and 5.30 mm height. It is suitable for power supply and DC-DC converter applications where high current handling and low DC resistance are required.
