Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TMCS1101A4UQDRQ1 is a galvanically isolated Hall effect current sensor capable of measuring DC or AC current with high accuracy, excellent linearity and temperature stability. The low-drift, temperature-compensated signal chain achieves < 1.5% full-scale error over the temperature range of the device.

Input current flows through an internal 1.8mΩ conductor, which generates a magnetic field that can be measured by an integrated Hall effect sensor. This eliminates the need for an external concentrator and simplifies the design. Low conductor resistance minimises power loss and heat dissipation. Inherent galvanic insulation provides 600V lifetime operating voltage and 3kVRMS basic isolation between the current path and the circuit. Integrated electrical shielding provides excellent common mode rejection and transient immunity.

The output voltage is proportional to the input current and features four sensitivity options. The fixed sensitivity allows the TMCS1101-Q1 to operate from a single 3V to 5.5V supply, thus eliminating proportionality errors and improving supply noise rejection. Current polarity is considered positive when current flows into the positive input pin. Unidirectional and bidirectional detection models are available.

• 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.
