MAWH automotive power inductor selection guide: decoding MAWH-1054-330-M-5A
MAWH part numbers such as MAWH-1054-330-M-5A belong to the regular automotive one-piece molded power inductor line of Kun Shan MAZO Tech Co., Ltd.. In the MAZO 2026-06 product overview the line is listed together with VCMA as "regular automotive integrated VCMA / MAWH": 16 size codes from 2.2 × 1.8 mm to 17.45 × 17.15 mm and 183 inductance values, all marked AEC-Q200.
MST is a distributor of MAZO parts, not the manufacturer. Every number on this page comes from the MAZO documents listed under Sources. MAZO has not published a separate MAWH datasheet, so where only the VCMA datasheets give a value we say so, and anything not published, such as the meaning of the "-5A" suffix, is left out. Request a quote and MST handles the rest.
How to decode MAWH-1054-330-M-5A
MAZO VCMA datasheets decode their part numbers as product series, dimensions, inductance value, tolerance and a final suffix. MAWH part numbers use the same field order, so MAWH-1054-330-M-5A reads as follows.
| Field | Value | Meaning | Source |
|---|---|---|---|
| Series | MAWH | MAZO regular automotive one-piece molded line, listed with VCMA | MAZO 2026-06 overview, automotive table |
| Size code | 1054 | Body 11.5 × 10.3 × 5.4 mm (L × W × H) | MAZO 2026-06 overview, automotive table |
| Inductance | 330 | Two digits plus a multiplier: 33 × 10⁰ = 33 µH. R marks a decimal point: 3R3 = 3.3 µH, R47 = 0.47 µH, 100 = 10 µH | VCMA datasheet part-number decode |
| Tolerance | M | ±20 % | VCMA datasheet decode; overview lists L0 ±20 % |
| Suffix | 5A | Not defined in any public MAZO document. In VCMA datasheets the suffix 1A marks the 125 °C grade | Request a quote |
MAZO also uses -5A on VCMA-0630-3R3-M-5A, MCSC-1080 and VCMU-0530 parts in the same overview. A matching suffix does not prove identical ratings.
The 16 MAWH / VCMA size codes
The size code is the first choice, because it fixes the footprint and height. The table is the MAZO 2026-06 automotive table; dimensions are maximum L × W × H and every series is marked AEC-Q200.
| Size code | L × W × H (mm) | L0 range (µH, ±20 %) | Values | AEC-Q200 |
|---|---|---|---|---|
| 201610 | 2.2 × 1.8 × 1.0 | 1.0 – 2.2 | 5 | Yes |
| 201612 | 2.2 × 1.8 × 1.2 | 0.10 – 1.5 | 9 | Yes |
| 252012 | 2.7 × 2.4 × 1.2 | 0.15 – 4.7 | 9 | Yes |
| 322512 | 3.4 × 2.7 × 1.2 | 0.47 – 4.7 | 4 | Yes |
| 322520 | 3.4 × 2.7 × 2.0 | 0.47 – 4.7 | 6 | Yes |
| 0420 | 4.75 × 4.45 × 2.0 | 0.10 – 6.8 | 13 | Yes |
| 0421 | 4.5 × 4.3 × 2.1 | 0.10 – 10.0 | 16 | Yes |
| 0530 | 5.7 × 5.4 × 3.0 | 0.33 – 10.0 | 10 | Yes |
| 0630 | 7.3 × 6.8 × 3.0 | 0.22 – 22.0 | 19 | Yes |
| 0854 | 8.4 × 8.0 × 5.4 | 1.0 – 33.0 | 7 | Yes |
| 1040 | 11.5 × 10.3 × 4.0 | 0.15 – 22.0 | 16 | Yes |
| 1050 | 11.5 × 10.3 × 5.0 | 0.68 – 68.0 | 19 | Yes |
| 1054 | 11.5 × 10.3 × 5.4 | 2.2 – 47.0 | 7 | Yes |
| 1350 | 13.8 × 12.9 × 5.0 | 0.22 – 33.0 | 17 | Yes |
| 1365 | 13.8 × 12.9 × 6.5 | 1.0 – 33.0 | 11 | Yes |
| 1770 | 17.45 × 17.15 × 7.0 | 0.47 – 68.0 | 14 | Yes |
Do not confuse the 1054 here with the 1054 of the MAZO VCMC / VCMT high-vibration series, which the same overview lists at 11.2 × 10.3 × 5.4 mm and 1.0 – 100 µH.
Choosing a size code
- Start from the inductance your controller needs and keep only the size codes whose range covers it. 33 µH, for example, is available in 0854, 1050, 1054, 1350, 1365 and 1770.
- Among those, pick by height and footprint: 1050 and 1054 share the 11.5 × 10.3 mm footprint at 5.0 and 5.4 mm height; 1350 and 1365 share 13.8 × 12.9 mm.
- A larger body for the same inductance generally gives more saturation and heating current and lower DCR, but check the exact values on the datasheet that MAZO supplies for your part number.
- Copy the land pattern from the MAZO drawing of the exact series. Bodies with similar size codes do not share footprints.
Electrical checks: Isat, Idc, DCR and temperature
The MAZO VCMA datasheets define saturation current (Isat) as the DC current that drops L0 by approximately 30 %, and heating current (Idc) as the DC current that causes an approximate 40 °C rise. The operating range is −55 °C to +125 °C including self-heating. Check Isat against the peak inductor current and the controller current limit, and Idc against the RMS current at your worst ambient.
For 1054 there is no public datasheet. Ask MAZO, through MST, for the datasheet of the exact MAWH part before layout. As a reference point only, the VCMA-1365-330-M-1A datasheet (a larger 13.8 × 12.9 × 6.5 mm body) gives 33 µH with DCR 39 / 45 mΩ (typ / max), Idc 7.0 / 6.5 A, Isat 8.5 / 8.0 A and 75 V rated voltage. A 1054 part will differ.
| Maker | Part number | L (µH) | DCR typ / max (mΩ) | Idc (A) | Isat (A) |
|---|---|---|---|---|---|
| MAZO | VCMA-0630-3R3-M-5A | 3.3 | 18 / 22 | 8.5 | 11 |
| Cyntec | VCMT0630-3R3MN5TM | 3.3 | 22.5 / 26 | 7.5 | 8.3 |
| Vishay | IHLP2525CZ-3R3M5A | 3.3 | 26.5 / 28.4 | 6.8 | 8.3 |
This comparison is published by MAZO; the competitor figures are as MAZO printed them. Check each maker datasheet, since test conditions differ.

Frequently asked questions
Who makes MAWH inductors?
Kun Shan MAZO Tech Co., Ltd.. MAZO lists MAWH with VCMA as its regular automotive one-piece molded line. MST is a distributor, not the manufacturer.
What does 1054 mean in MAWH-1054-330-M-5A?
It is the size code. The MAZO 2026-06 automotive table gives 11.5 × 10.3 × 5.4 mm and an inductance range of 2.2 to 47 µH for 1054.
What inductance is 330?
33 µH: two significant digits (33) followed by a multiplier digit (0). R is used as a decimal point, so 3R3 is 3.3 µH.
What does the -5A suffix mean?
MAZO has not published it. Its VCMA datasheets use 1A for the 125 °C grade. Request a quote for the exact part number and MST replies with the datasheet.
Is there a MAWH-1054 datasheet?
Not publicly. Ask MST for the MAZO datasheet of the exact part number; we request it from MAZO. Do not design from the VCMA values of a different size.
Are MAWH parts AEC-Q200?
The MAZO 2026-06 overview marks every VCMA / MAWH size code as AEC-Q200. Request a quote with your PPAP and change-notification needs.
What lead time should I expect?
The MAZO 2026-06 overview states about 1 week for samples and 4 to 6 weeks for mass production. MST confirms the current lead time with each quote.
