Vishay Intertechnology’s IHTH-1500MZ-5A high current through-hole inductor is built for engineers who are trying to squeeze more power into smaller EV, industrial and renewable-energy systems without sacrificing thermal headroom. The molded inductor family offers continuous currents up to roughly 57 A, very high saturation currents that can reach 200 A depending on inductance value, and an operating temperature range up to 155 °C at full rated current, making it a workhorse component for demanding power stages. Vishay’s official product page highlights its role in onboard chargers, DC-DC converters, and motor drives in electric vehicles and industrial equipment.

Where the IHTH-1500MZ-5A fits in today’s power designs

The IHTH-1500MZ-5A is a molded high-current inductor with a compact 38 mm by 38 mm footprint (length and width) and a low 15 mm profile, giving designers a relatively small component for handling tens of amps in PFC stages, high-power DC-DC converters and output filters. Vishay specifies inductance values from 0.22 µH to 4.7 µH with a typical DCR from the low fractions of a milliohm to a few milliohms, which helps minimize conduction losses in high-efficiency designs. In addition, the device is qualified to an operating temperature range from -55 °C to +155 °C, including self-heating, a range that aligns with the harsh environments of traction inverters, onboard chargers, and industrial motor drives where ambient temperatures and current spikes can be substantial. For EV and charging infrastructure designers, those ratings are particularly relevant because thermal derating of magnetics often becomes a bottleneck long before semiconductors reach their limits. To provide better clarity to designers, the IHTH-1500MZ-5A data is reflected in the component’s datasheet and related collateral, which emphasize its high saturation current capability and robust thermal characteristics. A current Mouser-hosted datasheet confirms the inductance range, current ratings and temperature performance.

Strategically, Vishay positions the IHTH-1500MZ-5A within a broader portfolio of power inductors that support trends such as 800 V EV architectures, higher switching frequencies with wide-bandgap semiconductors, and densification of industrial power supplies. By offering a through-hole package with robust mechanical anchoring, the component suits applications with vibration and shock, such as onboard vehicle electronics, heavy industrial drives, and railway systems. For designers who are standardizing around Vishay’s magnetics, the IHTH-1500MZ-5A serves as a flagship option for the upper end of current capability while still staying in a manageable board footprint. At the corporate level, Vishay has consistently highlighted its passive components and power semiconductor lines as core growth platforms in investor presentations and earnings calls, with magnetics and power inductors contributing to automotive, industrial and renewable-energy revenues. Shares of Vishay Intertechnology (ISIN US92823L1070) traded on the NYSE at $26.45 on 06/13/2026, underscoring how investors are valuing the company’s broad analog and passive component portfolio in a market increasingly focused on EVs and electrification, according to recent NYSE trading data summarized by financial portals such as MarketWatch’s listing for VSH.
