What each comparison means (7)
- Würth Elektronik 74437368022 (WE-LHMI 1040): Same inductance, 2.2 µH vs MAZO 2.2 µH. Saturation current 18.1 A (10% drop) vs MAZO 19 A typ. (30% drop), rated on different bases so not directly comparable; heating current 14.3 A (40 °C rise) vs MAZO 14 A typ. (40 °C rise). DCR 7 mΩ max vs MAZO 7 mΩ max. Body 11 × 10 × 3.8 mm vs MAZO 11.5 × 10.3 × 4 mm, MAZO 0.2 mm taller. Land pattern close to MAZO's: two 3.5 × 4.1 mm pads 5.4 mm apart vs MAZO two 4.1 × 4.1 mm pads 5.4 mm apart (pad width differs by 0.6 mm). Verdict: drop-in candidate (Idc about 2% lower at 40 °C rise, DCR equal).

Selection and use
How to select
Choosing inductance
L ≈ (Vin − Vout) × Vout ÷ (Vin × fsw × ΔI), with ΔI at 20–40% of the output current. The series covers 0.22–22 µH in one body, so changing the value needs no new layout.
Saturation current Isat
the current at which inductance falls about 30%; keep the peak current below it.
Heating current Idc
the current that raises the part about 40 °C above a 25 °C ambient; ambient plus rise stays within 125 °C.
DC resistance
sets the conduction loss. Typical 0.62–58 mΩ across the series; use the maximum for loss budgets.
Rated voltage
75 V maximum; check it against the input voltage.
Height
Max 4.0 mm. More current: VCMA-1350; smaller: VCMA-0630.
