Product Description

The V18039FJ amorphous magnetic ring is fabricated with premium 1K107B amorphous alloy, a high-performance magnetic material for power electronic filtering applications. This core achieves an ultra-high initial permeability of 80000 and a saturation magnetic flux density of 1250mT. It supports a wide operating temperature range from -50℃ to 150℃, paired with an outstanding Curie temperature of 570℃, ensuring exceptional thermal stability in complex working environments.

Boasting superior DC bias resistance and a low magnetostriction coefficient, this amorphous magnetic ring maintains steady magnetic properties despite drastic temperature fluctuations. Adopting standardized production procedures and rigorous quality testing, our products deliver stable and uniform parameters for mass procurement. Designed for efficient common-mode noise suppression and EMC optimization, this magnetic core is widely applicable in various power electronic devices. Customized solutions and sample testing services are available to meet diverse project demands.

Q: Why impedance test result differs on the same amorphous core sample? A: Impedance value changes with test frequency and DC bias condition. Different test setups will output different test data. Please refer to the corresponding test condition.
Q: Can amorphous magnetic ring work at high frequency? A: Amorphous cores perform well within several tens of kilohertz. Loss will rise obviously when frequency goes too high, not suitable for ultra‑high frequency scenarios.
Q: What causes performance inconsistency among amorphous core batches? A: It mainly comes from raw material stability, quenching process and heat treatment. Strict production inspection can control batch‑to‑batch deviation within acceptable range.
Q: Can amorphous magnetic ring be processed by cutting? A: Cutting will introduce heavy mechanical stress and destroy magnetic performance. Generally, finished toroidal amorphous cores cannot be cut for secondary modification.
Q: How to store amorphous magnetic rings properly? A: Store in dry room temperature environment. Avoid heavy pressing, dropping and corrosive gas. Insulation layer should be protected from scratch during storage.
Q: What is the failure mode of amorphous magnetic core in practical use? A: Main failures include magnetic performance degradation caused by mechanical stress, permanent failure due to over‑temperature crystallization, and insulation damage leading to winding short circuit.
