About Hongkong Niuyi Limited - Integrated Circuits Supplier in China

Hongkong Niuyi Limited is based in China and currently lists five active electronic component products. The catalogue includes the TLE4941-1C integrated circuit, the MMBF170LT1G discrete semiconductor, the 74AHC1G08GW logic gate IC, the TPS51216RUKR WQFN‑222+ integrated circuit, and the M74VHC1GT50DTT1G logic integrated circuit. All items fall under the broader categories of Integrated Circuits, Electric Components, and Electronic Semiconductor Devices as indicated in the supplier’s top‑category list. The products are identified by their standard part numbers and reflect typical device families used in automotive, consumer electronics, and industrial control applications.

The listed items cover a range of functional blocks: the TLE4941‑1C is a Hall‑effect sensor IC, the MMBF170LT1G is an N‑channel MOSFET, the 74AHC1G08GW is a high‑speed CMOS logic gate, the TPS51216RUKR is a step‑down voltage regulator in a WQFN‑222 package, and the M74VHC1GT50DTT1G is a high‑speed CMOS logic IC. Each product corresponds to a distinct HS‑code family commonly used for semiconductor devices, such as chapter 85 42 for integrated circuits and chapter 85 41 for semiconductor devices. The supplier’s catalogue therefore provides a concise set of components that are routinely sourced for PCB assembly and system design.

Product Range and Specialties of Hongkong Niuyi Limited

The catalogue focuses on discrete semiconductors and logic‑gate integrated circuits. Typical specifications for these categories include JEDEC standard grading (e.g., J‑STD‑033 for moisture sensitivity), voltage ratings from 3.3 V to 12 V for logic families, and MOSFET drain currents up to 250 mA for devices like the MMBF170LT1G. Packaging formats in the list include SOIC, QFN‑222, and thin‑film plastic packages, which are standard for surface‑mount technology (SMT) production lines. Buyers often request data sheets that detail parameters such as propagation delay (nanoseconds), power dissipation (mW), and switching speed (ns).

Trade and Export Information - Hongkong Niuyi Limited

China is a major exporter of semiconductor devices, with integrated circuits typically classified under HS 8542 and discrete components under HS 8541. Major import regions include Southeast Asia, the European Union, and North America, where buyers apply RoHS, REACH, and IEC 61340‑5‑1 standards for ESD protection. Export shipments from China frequently use FOB Shanghai or Ningbo, and containers are loaded in standard 20‑ft or 40‑ft units with anti‑static packaging. Buyers usually require certificates of conformity for RoHS and a test report confirming compliance with IEC 60730 for safety‑critical components.

Sourcing from Hongkong Niuyi Limited - Buyer Guidance

When sourcing from Hongkong Niuyi Limited, request the latest datasheet and a RoHS compliance certificate for each part. Verify the device’s packaging code (e.g., QFN‑222) against the buyer’s assembly line capability and confirm the moisture‑sensitivity level (MSL) to plan for proper handling. Typical minimum order quantities for single‑part SM‑T components range from 500 pieces to 5 000 pieces, with lead times of 2  -  4 weeks depending on stock availability. Ensure that the supplier provides ESD‑safe anti‑static bags and that the shipping documents list the correct HS code for customs clearance.

What types of semiconductor devices does Hongkong Niuyi Limited list?

The supplier lists five items: a Hall‑effect sensor IC (TLE4941‑1C), an N‑channel MOSFET (MMBF170LT1G), two CMOS logic gate ICs (74AHC1G08GW and M74VHC1GT50DTT1G), and a step‑down regulator IC (TPS51216RUKR). Each belongs to the integrated‑circuit or discrete‑semiconductor families commonly used in electronic assemblies.

Which packaging formats are included in the catalogue?

The products are offered in surface‑mount packages such as WQFN‑222, SOIC, and thin‑film plastic packages. These formats are compatible with standard SMT pick‑and‑place equipment and require anti‑static handling.

What HS‑code families apply to these products?

Integrated circuits like the logic gates and regulator fall under HS 8542, while discrete devices such as the MOSFET are classified under HS 8541. These codes are used for customs declarations in most importing countries.

What certifications should a buyer request for these components?

Buyers should request RoHS compliance certificates and, where applicable, IEC or JEDEC test reports confirming parameters such as voltage rating, current rating, and moisture‑sensitivity level. ISO 9001 certification is also commonly required for quality‑management verification.

What is the typical minimum order quantity and lead time?

MOQ for single‑part semiconductor items usually ranges from 500 to 5 000 units. Lead times are typically 2 to 4 weeks, depending on current inventory and production scheduling.

How are the items packaged for export?

Export shipments are packed in anti‑static bags within cardboard cartons, often stacked on pallets for container loading. This packaging meets IEC 61340‑5‑1 requirements for ESD protection during transport.

Which regions import similar semiconductor products from China?

Major importers include the United States, European Union member states, Japan, South Korea, and Southeast Asian markets such as Singapore and Vietnam, where electronics manufacturing hubs source these components.

What documentation is needed for customs clearance?

Customs typically requires a commercial invoice, packing list, and the correct HS code (8542 or 8541). Including the RoHS certificate and test report can expedite clearance under many regulatory regimes.
