Description
Application Specifications
Automotive Electronic Modules (Car Chargers & BCMs): Integrated into DC-DC Buck-Boost converter circuit boards for high-power USB fast-charging car docks and Body Control Modules. Audio Amplifiers & Communication Hardware: Embedded in LC output filter networks of Class-D audio amplifiers and wireless IoT gateway power rails. Smart Home & Qi Wireless Charging Stations: Placed on main power entry boards to prevent high-frequency magnetic fields from bleeding back into AC/DC grid power supply lines.
| Application Domain | Specific Implementation | Core Function |
| AutomotiveElectronic Modules (Car Chargers & BCMs) | High-power USB fast-charging car docks and Body Control Modules. | Blocks incoming voltage surges and high-frequency EMI. |
| Audio Amplifiers & Communication Hardware | Embedded in LC output filter networks of Class-D audio amplifiers . | Removes high-frequency switching carrier signals for pure audio output. |

Product Features
● High Saturation Current — stable inductance under peak load and start-up inrush● Open Magnetic Circuit — rod-type core resists saturation by design ● Ultra-Low DC Resistance — multi-strand oxygen-free copper, single-layer winding Wide Operating Temperature — -55 °C to +150 °C ● Broadband EMI Suppression — low-pass differential-mode filtering in LC / π networks ● Compact Through-Hole Body — axial or radial mounting for dense PCB layouts ● Optional Environmental Coating — polyolefin heat-shrink tubing or varnish
Product Advantages
● Keeps its inductance when the current surges. The open magnetic circuit holds the core out of saturation through load steps and start-up inrush.● Less loss, less heat. A single-layer winding of multi-strand oxygen-free copper keeps DC resistance low, which cuts conduction loss.● Built for hot, harsh locations. The construction is rated across a -55 °C to +150 °C operating window, so inductance and mechanical integrity hold up in engine-bay modules.● One part does two jobs. Used as the low-pass element in an LC or π-filter network, it attenuates high-frequency switching noise while it smooths ripple.● Simple structure, volume-ready cost. The unshielded rod body and single-layer winding use fewer parts and fewer process steps than a shielded bobbin design.

Quality & Testing Assurance
Incoming material control
Ferrite rod grade and copper wire type are verified against the specified grade before windingy.
In-process control
Turns count, winding pitch, lead-out routing and pin position are controlled at the winding station so the single-layer construction stays inside the drawing tolerance.
Electrical verification
Inductance and DC resistance are measured against the declared value for each part number.
Thermal verification
Assemblies are checked against the published -55 °C to +150 °C operating window.
Frequency and EMI performance
Samples are characterized across the operating frequency band to confirm the low-pass attenuation and the switching-noise suppression the design relies on.
Mechanical and visual inspection
Coil concentricity, pin straightness and coplanarity, base plate bonding and core-to-coil fixation are inspected before packing.
Environmental protection
Where polyolefin heat-shrink tubing or varnish coating is specified, coverage and adhesion are verified so the part resists moisture.
Traceability and packing
Lots are marked and recorded so a delivered part can be traced back to its production batcht.
