We display high reliability magnetics parts
◆Wire wound type DC/AC current sensor
It uses wire wounds to sense DC/AC current. It's capable of sense wide current range and very stable over wide temperatures. One of the benefits of wire wound type is contact less which just puts sensor on bus-bar to sensing the current by very accuracy and stay safe on high voltage line.
◆Rotor Position Sensor (RPS)
This is a good for angle sense for motor or any rotate products. It's available for light weight, Vcc power source, low power consumption and functional safety standard compliance and over-molding for IP compliance. It's magnet less and makes very highly reliable in harsh environments.
◆High Power 2 Phase interleaved coupled inductor
By the two of magnetics flux cancellation, core volume significantly reduced. We provide the solution more than 100kW with small scale and light weight. It can be used in one coupled inductor for two phases interleave, and it’s possible to use multiple coupled inductors for multi-phase interleave circuit.
In addition, we display High power planar transformer on IC demo board, Power Inductors and High voltage transformer and so on. Please visit our booth.
