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.
