1.5mH 18A High-Current Nanocrystalline Common Mode Choke
CMT2214BNA-152-18A-LF
Industrial-grade 18 A solution with low thermal rise and robust vibration resistance.
Engineered for high-current industrial drives and compact power conversion, the 1500 µH / 18 A CMT Series choke provides excellent EMI suppression while keeping DCR low for reduced heat generation. Its nanocrystalline core ensures reliable performance even under extended high-load conditions.
Conventional solutions often overheat or lose effectiveness at 18 A. The CMT Series addresses this with advanced winding technology that delivers stable impedance and thermal balance, ensuring long-term system reliability.
Rated for continuous operation up to 150 °C, the 1500 µH choke combines durability, vibration resistance, and consistent EMI performance, giving engineers confidence in passing EMC tests for heavy-duty automotive and industrial platforms.
Customization
Due to the solid background of our engineer team at ferrite powder territory, we could modify the core powder, design and produce the most suitable product to fit customer's applications. Except for the standard characteristic of our series specification, Coilmaster Electronics also offer the customization product with low minimum order quantity (MOQ), tighter tolerance, different inductance and frequency applications.
Leadtime
Coilmaster’s standard lead time is 6~8 weeks, in urgent case, the fast delivery program is available. For specific product series, we could send out the goods within 10 or 20 working days.
