The ESQ series Common Mode Choke from Erocore Enterprise Co., Ltd. is a dual-winding ferrite core inductor designed for EMI suppression and electromagnetic compatibility filtering. It uses a ferrite core with copper windings to attenuate common mode noise while preserving signal integrity in power supply and signal line applications. The series supports compliance with EMC regulations for industrial and consumer electronics, including switching power supplies, motor drives, and automotive systems.
Available configurations include pair and triple wire coils for high stability and balance, with options for tape and reel packaging to enable automatic surface mounting. The ferrite core material is standard for high-frequency noise attenuation, typically operating in the 1 MHz to 100 MHz range. Copper windings are standard 26-30 AWG for most ESQ variants, with typical insulation classes rated for 100-200V AC/DC.
Primary buyers include OEMs and EMS providers sourcing passive components for power electronics, industrial controls, and automotive ECUs. The ESQ series is distributed in bulk for B2B import, with packaging optimized for SMT assembly lines. Erocore Enterprise confirms RoHS compliance for all products, ensuring eligibility for export markets with environmental restrictions.

Before ordering the ESQ Common Mode Choke, verify the exact frequency range, current rating, and impedance values required for your application. Request a datasheet from Erocore Enterprise to confirm compatibility with your circuit design, particularly for high-frequency or high-power systems.
Confirm logistics details such as lead time, MOQ, and Incoterms with Erocore Enterprise, as these are not specified in the listing. The supplier’s location in Taiwan suggests potential for sea or air freight, but packaging and handling requirements for SMT components should be discussed upfront.
Perform incoming inspection to validate the choke’s performance against your EMI suppression targets. Test for insertion loss at your operating frequency and verify the physical dimensions match your PCB layout. Request a Certificate of Compliance for RoHS and any other relevant standards to ensure regulatory adherence.
