THT High Current Inductor

THT High Current Inductors from Nanjing Infinity Technology (INF) are engineered for demanding power electronics. Through-hole construction delivers robust current handling, reliable thermal paths, and secure mechanical anchoring. As a custom magnetic component solutions expert and B2B manufacturer in Nanjing, China, we support tailored designs from R&D to production.

We configure inductance ranges, low DC resistance for efficiency, high saturation current, and suitable operating temperatures. Options include shielded or open magnetic structures, ferrite, metal alloy, or iron powder cores, flat or round windings, and impregnation or potting for vibration resistance.

Features and Advantages of THT High Current Inductors

• Efficiency: minimized copper loss and controlled temperature rise at high RMS current.
• Power density: strong DC bias tolerance to maintain inductance under load.
• Material tuning: low core loss matched to switching frequency and ripple.
• EMI control: shielded designs reduce leakage fields in dense layouts.
• Reliability: durable leads, secure mounting, and reinforced construction.

EMI and shielding in through-hole high current inductors

Shielded builds help contain stray flux and support conducted and radiated EMI targets. Open structures suit generous spacing or heightened thermal needs when emissions budgets allow.

Core materials and construction

Ferrites minimize core loss at higher frequencies. Metal alloy cores offer soft saturation and strong bias performance. Iron powder provides distributed gaps and thermal robustness. We supply radial, axial, and toroidal forms to fit your layout and creepage/clearance needs.

Applications

INF supports industrial control, telecom and 5G infrastructure, new energy systems, medical equipment, and automotive electronics. Use these inductors for AC‑DC and DC‑DC stages, PFC input chokes, chargers, inverters, and storage converters where stable regulation and thermal reliability are critical.

Selection Guidance for THT High Current Inductors

Start with electrical targets, then finalize materials and mechanics to meet compliance and cost goals. Our engineers balance saturation margin, DC resistance, core loss, and EMI to match your topology.

Key selection factors for THT High Current Inductor

• Inductance value, ripple current, and switching frequency.
• Saturation current with margin for transients and faults.
• Allowable temperature rise at maximum RMS current.
• Core choice, shielding needs, mounting orientation, and insulation class.

Testing, Quality, and Compliance

Quality is controlled under ISO9001. As applicable, product conformance can align with UL, CE, and RoHS. Typical verification covers electrical parameters across temperature, thermal rise at rated current, and mechanical checks for solderability and vibration.
