Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the wave of rapid development of industrial automation, new energy vehicles and smart grids, high-speed optocouplers and optical isolation amplifiers, as the "safety guards" of signal isolation and transmission, have become core components for ensuring the anti-interference ability of systems and enhancing electrical safety. However, technological iterations and supply chain fluctuations have led to a large number of enterprises piling up brand-new inventories, occupying cash flow and warehousing resources. Shenzhen Mingjiada Electronics Co., LTD., relying on over ten years of professional recycling experience, is now offering a long-term high-price recycling service for high-speed optocouplers and optical isolation amplifiers of all brands and only brand new genuine products to the global market. With three core capabilities - scientific assessment, a global premium network, and environmentally friendly and compliant processing - we help enterprises unlock asset value and promote the green and circular development of the electronics industry!

I. Core Recycling Categories: Focus on high-performance isolation devices

Mingjiada Electronics focuses on recycling two high-value components, covering the full range of industrial and automotive scenarios:

High-speed optocoupler

Technical features: The transmission rate reaches 1-10 MBD, the response time is as low as 1μs, and it supports high dynamic scenarios such as RS-422/485 communication, motor control and switching power supply.

Key models: such as the Broad HCPL-7800 series (current detection), ACPL-K30T-560E (automotive-grade gate drive, withstand voltage 5000Vrms), etc., which need to be brand new original SOP/QFN packages.

Optical isolation amplifier

Technical features: It adopts Σ-Δ analog-to-digital conversion and optical coupling technology, with a gain accuracy of ±0.5% (such as ACPL-C87BT), supports ±40V isolation withstand voltage, and is suitable for high-precision voltage/current detection in motor inverters and battery management systems.

Automotive-grade models: such as ACPL-C87BT-000E (compliant with AEC-Q100 certification, operating within a wide temperature range of -40℃ to 125℃), new batches are given priority for recycling.

Note: Only unused new components with intact original factory packaging and clear codes are accepted. Refurbished or loose parts are not included in the recycling scope.

Ii. Core Advantages of Mingjiada Recycling Services

Professional technicians: Verify the original factory code and packaging information to eliminate the risk of counterfeiting. The premium space for brand new genuine products can reach 15%-30%.

2. High-price recycling: Automotive-grade optocouplers (such as ACPL-K30T) are sold to Tier 1 suppliers of new energy vehicles at a premium of 35% through the North American channel.

Iii. Why Choose Recycling? Technological iteration has given rise to the urgent need for inventory optimization

Three major trends drive enterprises to urgently revitalize silent assets:

Energy efficiency standard upgrade: The EU mandates that the standby power consumption of consumer electronics be less than 75mW, and the new generation of optocouplers (such as the low-power ACPL-C87B series) is accelerating the replacement of the old models;

Material technology innovation: The popularization of SiC/GaN power devices has led to a decline in the demand for traditional silicon-based drive optocouplers.

Supply chain redundancy: In 2024, the global inventory overstock rate of optocouplers exceeded 35%, and the warehousing cost for enterprises was as high as 120,000 yuan per ton per year.

Four. Four-step Rapid Monetization process: From assessment to payment collection, it only takes 5 days

Mingjiada's standardized path shortens the capital recovery cycle:

List submission: Organize the model (such as ACPL-C87BT-000E), quantity, package type (SO-8) and batch code;

Online evaluation: Email the list to sales@hkmjd.com and receive the grading quotation within 1 hour;

Safe delivery: Supports inspection at the Shenzhen warehouse, cross-border pick-up in the Hong Kong Free Trade Zone or DHL global cash on delivery, with full insured transportation throughout the process.

Acceptance and payment: The payment will be completed within T+1 working days after quality inspection. Multi-currency settlement is supported and a confidentiality agreement will be signed.
