Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the explosive growth of smart grids, industrial backup and new energy vehicles, supercapacitors (EDLC) are becoming the core energy storage units of highly reliable systems, thanks to their 100,000-cycle life and second-level charging and discharging capabilities. ADI's supercapacitor charger IC defines the peak standard of EDLC control technology through millivolt-level voltage equalization, intelligent energy management and automotive-grade reliability. However, technological iterations and project changes have turned a large number of brand-new original charger ics into "silent assets" for enterprises, facing an average annual value depreciation of 20%. Shenzhen Mingjiada Electronics Co., LTD., relying on its ten years of expertise in power management chip recycling, has specially launched a high-price recycling service for ADI's full range of supercapacitor charger ics, helping customers revitalize their inventory assets and jointly build a green and circular ecosystem for the electronics industry.

I. ADI Technology Benchmark: Redefining the Boundaries of EDLC Energy Management

1. Precise charging control: Breaking through the EDLC lifespan bottleneck

LTC3350 series: Supports 1.5V to 5V single-cell/multi-cell EDLC charging, with ±0.5% charging voltage accuracy and ±2% current accuracy, and the cycle life is extended to 150,000 times (such as LTC3350EUHF#PBF).

Active voltage balancing: Each capacitor is independently monitored (such as LTC3355), eliminating the overvoltage risk of series EDLC and enhancing system reliability by five times.

Intelligent thermal management: Dynamically adjust the charging current from 1A to 5A (such as LTC4041), and the temperature rise control is better than 10℃ (@5A).

2. System-level energy hub

Bidirectional energy conversion: The LTC4041 supports both step-down charging and step-up backup. The efficiency of converting 12V to 5V reaches 96%, and the power-off switching time is less than 1ms.

Digital monitoring interface: I²C programmable charging parameters (such as LTC3351), real-time reporting of capacity decay rate and ESR value.

3. Reliability in extreme environments

Automotive-grade guardians (such as LTC3350) : Certified by AEC-Q100, they can withstand temperature cycles ranging from -40 ° C to 125 ° C and mechanical shock of 50g.

Industrial-grade robustness (such as LTC4425) : Reverse connection/short-circuit protection design, capable of withstanding 80V surge impact (ISO 7637-2 standard).

Mingjiada high-price purchase of key models

Multi-section balanced flagship: LTC3355EUHF#PBF (5A/5.5V), LTC3351IUHF#PBF (I²C interface), with a premium rate as high as 30%.

Automotive-grade dedicated solution: AEC-Q100 certified models (such as LTC3350IUHF#PBF) are priced at a 25% premium.

The high current industrial model: LTC4041EUDC#PBF (5A) has a premium of 18% due to the urgent need for power grid equipment maintenance and repair.

Ii. Mingjiada Recycling System: A Scientific Closed Loop of Technological Authentication and Global Premium

1. Factory-level inspection and data erasure

Wafer authenticity verification: X-ray scanning and comparison of ADI wafer microcodes, opening the cover for analysis to verify the ball bonding process (refurbished chip rejection rate >99.9%);

Full-function load test: Verify charging accuracy in a -55℃ to 125℃ incubator, and detect active balancing performance with a dedicated EDLC module.

Sensitive parameter erasure: Physically erase the I²C configuration data of LTC3351, certified by NIST SP 800-88.

2. Dynamic Supply and Demand pricing model

Based on the global new energy maintenance market database, Mingjiada offers excess returns for three types of ics:

Grid energy storage shortage model: LTC3355, which supports multi-section series connection, has a 35% premium due to the UPS maintenance requirements of substations.

Packaging status bonus: Unrolled tape material (original factory vacuum packaging + desiccant) is subject to an additional 7% price increase.

Batch stepped reward: If the single recycling exceeds 5,000 pieces, the unit price will increase by another 4%.

3. ESG compliance regeneration

Chip-level reuse: After aging tests, fully functional ics enter the industrial equipment aftermarket.

Green extraction of precious metals: Anaerobic pyrolysis of non-reusable chips for gold/palladium recovery, reducing carbon footprint by 82% (compared with mineral mining).

Three and four-step rapid monetization: Global funds arrive within 5 days

Mingjiada's standardized process breaks down traditional recycling barriers

Encrypted list submission: Organize model (such as LTC4041EUDC), quantity, package photo and send to sales@hkmjd.com, and get the pre-price within 20 minutes;

Safe delivery: Optional delivery at Shenzhen/Singapore/Houston inspection centers, or FedEx global insured cash on delivery (moisture-proof + anti-static packaging).

Payment upon inspection: Full payment will be made by telegraphic transfer within 24 hours of arrival. Settlement is supported in US dollars/euros, and the entire process is compressed to 5 working days.

Conclusion: Reshaping the energy technology ecosystem through strategic recycling

Mingjiada Electronics builds a "golden outlet" for energy management chip inventory for enterprises by integrating ASIL-D-level detection capabilities, global maintenance market data and zero-risk data clearance. Choosing professional recycling is not only a rational decision for asset optimization but also a responsible move to participate in the green upgrade of the new energy industry.
