74435573300 Description

Short technical summary and product information.

The Würth Elektronik 74435573300 is a WE-HCI series shielded SMT high-current power inductor. It features a nominal inductance of 33µH with ±20% tolerance, measured at 100 kHz / 10 mA. The rated current is 8.5A maximum (ΔT = 50 K) with a performance rated current of 8.7A (ΔT = 40 K). Saturation current is 8A typical at 10% inductance drop and 9A typical at 30% drop. The DC resistance is 21.7mΩ ±8% at 20°C. Self-resonant frequency is 9.5 MHz typical.

 

This inductor uses a shielded metal composite core and wirewound construction, making it suitable for high-current applications with low EMI. It is AEC-Q200 qualified for automotive use and operates over -40°C to +125°C ambient range. The component is housed in a nonstandard 1890 package (18.30mm x 18.20mm x 9.20mm) for surface mount assembly.

 

Ideal for DC-DC converters, power supplies, and EMI filtering in automotive, industrial, and consumer electronics where high current handling and compact size are required. The component is RoHS3 compliant and REACH unaffected.
