Short answer: MAWH-1054-330-M-5A is a Kun Shan MAZO Tech Co., Ltd. regular automotive molded power inductor: series MAWH, size code 1054 (11.5 × 10.3 × 5.4 mm), inductance 330 = 33 µH, tolerance M = ±20 %, and a -5A suffix that MAZO has not decoded publicly, so confirm it with MAZO. The full guide with all 16 size codes is at [MAWH automotive power inductor selection guide](/buying-guides/mawh-automotive-power-inductor-selection-guide).
MST distributes MAZO parts and is not the manufacturer. Values come from the MAZO 2026-06 product overview (regular automotive VCMA / MAWH table) and the MAZO VCMA datasheets. MAZO has not published a separate MAWH datasheet.
Step 1: Read the part number

| Field | Value | Meaning |
|---|---|---|
| Series | MAWH | MAZO regular automotive one-piece molded line, listed with VCMA |
| Size code | 1054 | 11.5 × 10.3 × 5.4 mm |
| Inductance | 330 | 33 µH (R is a decimal point: 3R3 = 3.3 µH) |
| Tolerance | M | ±20 % |
| Suffix | 5A | Not publicly defined; VCMA datasheets use 1A for 125 °C. Confirm with MAZO |
Step 2: Pick the size code
The MAZO 2026-06 table lists 16 size codes and 183 values, all marked AEC-Q200. For 1054 the range is 2.2 to 47 µH. Do not confuse it with the 1054 of the VCMC / VCMT high-vibration series (11.2 × 10.3 × 5.4 mm, 1.0 to 100 µH).

33 µH is offered in 0854, 1050, 1054, 1350, 1365 and 1770. 1050 and 1054 share the 11.5 × 10.3 mm footprint at 5.0 and 5.4 mm height.

Step 3: Check Isat, Idc and temperature
MAZO VCMA datasheets define Isat as the current for about 30 % inductance drop and Idc as the current for about 40 °C rise, with −55 °C to +125 °C including self-heating. Ask for the datasheet of the exact MAWH part. For reference only, VCMA-1365-330-M-1A (a larger body) gives 33 µH, DCR 39 / 45 mΩ, Idc 7.0 / 6.5 A, Isat 8.5 / 8.0 A.

Step 4: Approve and order

AEC-Q200 is not program approval: confirm PPAP, change notification and the suffix meaning with MAZO. The overview quotes about 1 week for samples and 4 to 6 weeks for mass production.
