What each comparison means (8)
- TDK SPM5030T-3R3M-HZ (SPM5030T-HZ): Same inductance, 3.3 µH vs MAZO 3.3 µH. Saturation current 4.3 A (20% drop) vs MAZO 7.5 A typ. (30% drop), rated on different bases so not directly comparable; heating current 6.5 A (40 °C rise) vs MAZO 4.8 A typ. (40 °C rise). DCR 29.5 mΩ max vs MAZO 37 mΩ max. Body 5.2 × 5 × 3 mm vs MAZO 5.7 × 5.4 × 3 mm. Land pattern close to MAZO's: two 2.2 × 1.5 mm pads 2.7 mm apart vs MAZO two 2.5 × 1.9 mm pads 2.2 mm apart (gap differs by 0.5 mm). Verdict: MAZO figures are weaker, consider only with ample margin (Idc about 26% lower at 40 °C rise, DCR slightly higher). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise, the land pattern against both drawings and test samples.

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 0.33–10 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 4.5–110 mΩ across the series; use the maximum for loss budgets.
Rated voltage
50 V maximum; check it against the input voltage.
Height
Max 3.0 mm. Lower: VCMA-0420; same height, more current: VCMA-0630.
