MH&W International Corporation

MH&W International Corporation, headquartered in Mahwah, New Jersey and founded in 1964, is a diversified distributor of electronic and thermal management components serving industrial sectors including water treatment, pulp and paper, energy, food processing, HVAC, and agriculture. The company operates through five divisions — Power Quality, Cores and Components, Thermal Interface Materials, Gaskets and Seals, and Semiconductors — each targeting distinct but complementary segments of the electrical and electronics supply chain. In the Power Quality division, MH&W distributes CoolBlue and NaLa nanocrystalline inductive absorbers for mitigating EMI and bearing currents in VFD-driven motor systems, CoolTube radiated emissions absorbers, EPA electronic power line filters, and SmartD variable frequency drives. Their Cores and Components division supplies ferrite cores from TDK, EPCOS, Acme, and Cosmo, alongside powder cores (MPP, High Flux, Sendust, and Mega Flux variants) and Magnetec nanocrystalline cores for EMI filters and common mode chokes. The Thermal Interface Materials division offers Keratherm gap filler pads, thermal films, thermal grease, and Chang Sung thermal products for heat dissipation in power electronics. While their core business centers on electrical power quality and thermal management, the company's VFD filters and absorbers have direct applicability to water treatment facilities that rely on variable frequency drives for pump and aeration motor control, making their power quality product line tangentially relevant to the water and wastewater equipment market.
