Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MLX91217LVA-ACR-000-RE is part of a 2.5 generation high-speed current sensor product family aimed at inverter/converter applications. This current sensor measures current in the range of ±50A to ±5000A using conventional Hall effect technology (using an external ferromagnetic core to concentrate the signal). The magnetic flux density within the air gap of the ferromagnetic core is measured using embedded Hall effect technology and amplified to a fast analogue output proportional to 5V full scale. This novel CMOS Hall effect sensor offers a variety of factory calibrated offset, sensitivity and filter settings, but can be reprogrammed by the customer using the Melexis programming device PTC-04.

The current sensor's SIP4-VA package allows the sensing element to be inserted into a tight slot in the ferromagnetic core, and the sensor leads are available in a variety of adjustments and routing options, giving designers greater flexibility for mechanical integration and assembly.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
