Common Mode Power Line Choke (Horizontal)

Common Mode Power Line Choke (Horizontal) components suppress common-mode noise on AC/DC mains in a low-profile, through-hole package. Our China-based team designs and manufactures custom magnetic solutions with in-house R&D and application engineering. We tailor each choke to your electrical targets and mechanical envelope, and provide rapid samples for fast validation.

Advantages of Common Mode Power Line Choke (Horizontal)

Horizontal mounting delivers reduced height, a low center of gravity, and strong solder-joint stability under vibration. We tune inductance and impedance versus frequency, rated current, DCR, isolation voltage, and creepage/clearance to fit your standards and layout. Production follows ISO9001 processes, with support for UL/CE considerations and RoHS materials. Designs address elevated temperature and shock typical of industrial and automotive environments.

Horizontal Choke Series: SQ, ET, UU

SQ series uses a toroidal core on a rigid base for balanced impedance and low DCR in SMPS inputs. ET series targets height-constrained racks and shelves, maintaining impedance across broad frequencies with optimized turns and wire gauge. UU series adds bobbin insulation and controllable creepage paths for higher isolation in medical and safety-sensitive equipment.

Materials for Horizontal Common Mode Power Line Chokes

NiZn ferrite excels at high-frequency attenuation with low loss. MnZn ferrite delivers strong low-to-mid frequency impedance with high permeability. Nanocrystalline cores provide high impedance density and thermal stability in compact footprints. Our engineers map your EMI spectrum to the right material, core size, and turns count to meet current, DCR, and temperature-rise limits.

Applications and Standards for Horizontal Common Mode Chokes

Typical uses include switch-mode power supplies, industrial drives, EV auxiliaries and charging gear, telecom/5G rectifiers, medical modules, security electronics, and computing/servers. We supply datasheets, drawings, and test data to streamline pre-compliance and certification workflows, including UL/CE considerations and RoHS conformity.

Selection Guide for Horizontal Common Mode Power Line Chokes

Define your environment and EMI targets, then translate them into materials, core geometry, windings, and pinout. Prioritize:

• Isolation voltage, insulation class, and required creepage/clearance.
• Impedance versus frequency aligned to regulatory limits.
• Rated current and DCR to control loss and temperature rise.
• Maximum height, footprint, and vibration robustness.
