Description
Application Specifications
Automotive electronic modules (on-board charger and BCM): Integrated into DC-DC buck-boost converter circuit boards for high-power USB fast-charging car mounts and body control modules. Audio amplifiers and communication hardware: Embedded in LC output filter networks of Class-D audio amplifiers and wireless IoT gateway power rails. Smart home and Qi wireless charging stations: Placed on main power input boards to prevent high-frequency magnetic fields from feeding back into AC/DC mains lines.
| Application Field | Specific Implementation | Core Function |
| Automotive electronic modules (on-board charger and BCM) | High-power USB fast-charging car mounts and body control modules. | Block input surge voltage and high-frequency EMI. |
| Audio amplifiers and communication hardware | Embedded in LC output filter networks of Class-D audio amplifiers. | Remove high-frequency switching carrier signals for clean audio output. |
| Smart home and Qi wireless charging stations | Placed on main power input boards | Ensure system stability and compliance. |
Product Features
● High saturation current – maintains stable inductance under peak load and inrush surge ● Open magnetic circuit – rod core design resists saturation ● Ultra-low DC resistance – stranded oxygen-free copper, single-layer winding ● Wide operating temperature – -55 °C to +150 °C ● Wideband EMI suppression – low-pass differential-mode filtering in LC/π networks ● Compact through-hole package – axial or radial mounting for high-density PCB layouts ● Optional environmental coating – polyolefin heat-shrink tubing or varnish
Product Advantages
● Maintains inductance during current surges. The open magnetic circuit prevents core saturation during load steps and startup surges. ● Low loss and minimal heat generation. Stranded oxygen-free copper single-layer winding keeps DC resistance low, reducing conduction losses. ● Suitable for high-temperature harsh environments. The structure is rated for an operating window of -55 °C to +150 °C, with stable inductance and mechanical integrity in engine bay modules. ● Dual-purpose. As a low-pass element in LC or π filter networks, it attenuates high-frequency switching noise and smooths ripple. ● Simple structure and low mass production cost. The shieldless rod body and single-layer winding use fewer parts and simpler processes compared to shielded bobbin designs.

Quality and Testing Assurance
Incoming Material Control
Before winding, ferrite rod grade and copper wire type are verified against specified grades.
Process Control
Turn count, winding pitch, lead routing, and pin position are controlled at the winding station to ensure the single-layer structure remains within drawing tolerances.
Electrical Verification
Inductance and DC resistance are measured per part number at nominal values.
Thermal Verification
Components are checked according to the published -55 °C to +150 °C operating temperature range.
Frequency and EMI Performance
Samples are characterized within the operating band to confirm low-pass attenuation and switching noise suppression as designed.
Mechanical and Visual Inspection
Before packaging, check coil concentricity, pin straightness and coplanarity, base bonding, and core-to-coil fixation.
Environmental Protection
If polyolefin heat-shrink tubing or varnish coating is specified, verify coverage and adhesion to ensure moisture resistance of the part.
Traceability and Packaging
Lots are marked and recorded so shipped parts can be traced to their production batch.
