0.8*4*15*12.5T Magnetic Bar Inductor Copper Wire Bobbin Coils R Bar Inductor Filter
1.Product Description
This 0.8*4*15*12.5T Magnet Stick Inductor is made of copper wire wound skeleton coil structure, which is a high quality choice for R type magnet stick filter inductor. The 0.8mm wire diameter copper wire with 4mm bar diameter and 15mm bar length in its specifications is precisely wound through 12.5 turns to form a highly efficient electromagnetic induction unit. The high permeability core of the rods effectively suppresses high-frequency clutter and achieves excellent filtering performance in the 50Hz-200kHz frequency band, reducing ripple and interference signals in the circuit and improving the stability of power supply or signal transmission. The compact size is easy to integrate into small electronic devices, suitable for power adapters, automotive electronic systems, wireless communication modules and other scenarios. The copper wire material has low DC resistance characteristics, reducing inductor loss and improving circuit energy efficiency. Combined with the precision winding process and moisture-proof insulation treatment, it ensures stable operation in complex electromagnetic environments and temperature and humidity variations, and provides reliable filtering and energy storage functions for electronic circuits.
1. Precise filtering performance: 12.5-turn precision winding with high permeability magnetic bar, in the 50Hz-200kHz band effectively suppresses stray waves, significantly reduces ripple interference and ensures pure signal transmission.
2. High efficiency and low consumption design: 0.8mm copper wire with low DC resistance reduces its own energy loss and improves the energy efficiency of the circuit, resulting in significant energy saving.
3. Compact and adaptable: 4mm diameter, 15mm length, compact size, easy to integrate into space-constrained power adapters, car electronics and other small devices.
4. Good environmental adaptability: moisture-proof insulation treatment combined with high-quality materials, can work stably in complex temperature and humidity and electromagnetic environment, to ensure long-term reliable operation.
5. Reliable process quality: Rigorous winding process and quality control to ensure high consistency of inductor parameters, stable product performance, suitable for a variety of filtering and energy storage needs.
