- HIGH-AL MNZN FERRITE CORE – Premium MnZn ferrite optimized for HF/MF band RFI suppression, HAM baluns, power supply EMI filters, and audio transformers. AL≈3200nH ensures fewer turns for lower copper loss and cooler operation.
- STACKABLE FLAT DESIGN – Precision-ground flat top/bottom allows secure stacking to boost power handling for high-watt baluns and EMI filters.
- SMOOTH CHAMFERED EDGES – Burr-free and wire-safe. Protects enameled magnet wire & coax insulation during winding for EMI filters and transformers.
- BATCH-CALIBRATED WINDING GUIDE – Inductance formula: uH=(AL×Turns²)/1000. Your specific batch's actual AL value and pre-calculated turns (160m-10m) are printed on the label affixed to your protective case – follow that for guaranteed performance! Reference turns for AL≈3200: 8T/6T/4T/3T/2T.
- PROTECTIVE HARD CASE PACKAGING – Each core comes in a sturdy plastic case to prevent damage, ensuring your EMI filter project starts with a quality core.
