Product Description
10uH High Current Toroidal Choke Inductor AS777026 for Solar Inverter UPS OBC
AS777026 10uH High Current Toroidal Inductor for PFC, Boost & Output Filtering. This 10uH high current toroidal power inductor features a closed magnetic core wound with multi-strand thick copper wire. Designed for high-power switching applications where low DCR, low temperature rise and low EMI radiation are critical — including PFC/boost stages, UPS and inverter output filters, solar (PV) and energy-storage converters, OBC and EV charging modules, and industrial SMPS. The component is supplied on a PCB base plate with fully sleeved lead-out wires for direct and safe mounting into customer power boards.
Key Features
- Toroidal closed magnetic core — minimizes flux leakage and external interference, facilitating EMC testing compliance
- Multi-strand thick copper winding — provides ultra-low DCR and low temperature rise under continuous high current
- Fully sleeved windings — high insulation level on every lead-out, preventing insulation breakdown and creepage failures
- Stable 10uH inductance with soft saturation behaviour, maintaining ripple current control across the load range
- Epoxy-bonded to PCB base plate — strong mechanical fixing, vibration resistant, suitable for automatic or manual assembly
- Wide operating temperature range (-40°C ~ +125°C) for outdoor, industrial and automotive-grade environments
- Full customization (ODM/OEM) — inductance, current rating, core material, wire gauge, terminal style and base size tailored to your specifications

- Flexible MTO capacity for both prototype quantities and mass production schedules
FAQ
Q1: Can the inductance be changed from 10uH to another value?
Yes. The AS777026 platform covers 1uH to 10mH. Tell us the target inductance, DC bias current and switching frequency, and we will re-calculate the core and turns.
Q2: Which core material will you use for my design?
Sendust and High Flux are typical for high DC-bias PFC/boost applications; ferrite or nanocrystalline is used for high-frequency or common-mode filtering. Our engineers choose the material based on your frequency and loss budget.
Q3: Do you provide samples?
Yes. Drawing confirmation within 3 days and samples within about 7 days after specification is frozen.
Q4: What is the lead time for mass production?
Typically 15 - 25 days after sample approval and PO confirmation, depending on quantity and material availability.
Q5: Can you make the product to our own drawing or UL/safety requirement?
Yes. Full OEM/ODM is supported, including customer drawings, UL-recognized insulation materials, triple insulated wire (TIW) and specific creepage/clearance requirements.
