MDA4020-3R3M: 3.3 uH 3.5 A Molded Power Inductor

Alloy-molded power inductor suited to point-of-load synchronous buck converters. 3.3 uH at +/-20 percent with a 3.5 A temperature-rise rating, 3.1 A saturation current and 65 mohm DCR, in a shielded 4.5 x 4.1 mm molded body.

Key specs

Parameter Value
Inductance 3.3 uH +/-20 percent
Rated current 3.5 A (temperature rise)
Saturation current 3.1 A
DC resistance 65 mohm
Body 4.5 x 4.1 mm molded, shielded

Where it is used

The buck output inductor (L101) of the AP62300TWU-7 3.3 V buck stage on the Large Automotive Eth Switch Molecule. The footprint in this package uses the CKCS4020 land pattern, which matches the 4020-size molded body.
