The official website - Shenzhen Mingjiada Electronic Co., LTD
Under the intensifying fluctuations in the global semiconductor supply chain and the wave of green and low-carbon transformation, electronic manufacturing enterprises are facing the dual pressure of inventory overstock and capital turnover. As a leading enterprise in the field of electronic component recycling, Shenzhen Mingjiada Electronics Co., LTD., relying on nearly three decades of industry accumulation, has specially launched the efficient recycling service of (Renesas) data converters. With the core advantages of technology premium, global circulation and lightning settlement, it helps enterprises convert redundant inventory into working capital and drives the resource circulation of the industrial chain.
Recycling Core: The technical benchmark for defining the accuracy of the signal chain
Mingjiada focuses on Renesas' six major types of data converters, covering the full range of scenarios from nanovolt-level measurement to GSPS-level sampling:
High-precision ADC: The "Perception Cornerstone" of Industrial Automation
SAR ADC: 24-bit resolution models (such as the HSADC series) support ± 0.5LSB INL error and are used for pressure/temperature sensing in PLC systems, increasing production line yield by 3%.
Delta-Sigma ADC: Integrated programmable gain amplifier (PGA), enabling microvolt-level ECG signal acquisition in medical monitoring devices, with a common-mode rejection ratio >120dB.
2. High-speed ADC: The "Spectrum Catcher" of 5G and Radar
ADC with sampling rates ranging from 40MSPS to 500MSPS: Supports 8-16 bit resolution, applied in the intermediate frequency sampling of Huawei 5G base stations, with a signal-to-noise ratio (SNR) of up to 74dBc, meeting the 3GPP EVM specification.
Resolver - digital converter: Converts the motor rotor position signal into 16-bit digital quantity, replacing the photoelectric encoder, and improves the vibration resistance performance by 10 times.
3. Voltage Reference Source: The "Guardian of Weights and Measures" for Precision Systems
Floating Gate Array ™ (FGA™) technology: With a temperature drift as low as 3ppm/℃ (such as the ISL21090 series), it provides an initial accuracy of ±0.02% for industrial instruments and requires no calibration throughout its life cycle.
Bandgap reference source: 1.2V output noise <4μVpp, making it an ideal partner for high-precision Dacs.
4. Digital Potentiometer (DCP) and DAC: The "Tuning Center" of Dynamic Systems
32-tap high-resolution DCP: Replacing mechanical potentiometers, it enables digital calibration of resistance values in Tesla's BMS and can withstand 1 million adjustments.
16-bit high-speed DAC: Establishment time <1μs, driving the galvanometer control system of industrial laser engraving machines, positioning accuracy up to 0.001°.
Value engine: Technology scarcity and compliant circulation drive high premiums
Mingjiada's recycling pricing mechanism deeply integrates three dimensions: technological scarcity, terminal essential demand, and environmental compliance.
Premium for discontinued models: Early industrial-grade SAR ADCs (such as HSADC2412) can be recycled at 60% to 80% of their original value due to the maintenance and repair needs of medical equipment.
High-reliability version bonus: The premium rate of automotive-grade ADC (AEC-Q100 certified) and aerospace-grade voltage reference source (QML-V anti-radiation) is 25%-30% higher than that of consumer-grade.
Premium for unopened whole rolls: For devices that retain the original factory vacuum packaging and batch labels, an additional 3% will be charged.
Ultra-fast four-step monetization: From inventory overstock to capital Recovery
Mingjiada has established a standardized global recycling process, achieving a full closed loop within 5 working days
List submission: The customer organizes the model, quantity, and batch information (such as RAJ series or RICHTEK battery IC) and sends it to the evaluation email.
Video verification: Confirm the status of the original factory packaging and labels through video connection within 24 hours to avoid the bottleneck of cross-border inspection.
Safe delivery: Supports global door-to-door pick-up (covering Japan/America/Europe/Southeast Asia) or international insured logistics. Professional anti-static packaging ensures zero-damage transportation.
Payment upon inspection: Full payment is completed within 48 hours of arrival. Multi-currency settlement is supported, and the capital recovery speed is three times faster than the industry average.
Global service network: Dual guarantees of professionalization and compliance
The core competitiveness of Mingjiada stems from its technological accumulation and global layout:
Precise assessment capability: The technical team is proficient in the Renesas product line, eliminating 100% refurbished/counterfeit products.
Formal channel guarantee: Only accept formal sources of goods from agents, terminal factories and traders. Sign NDA agreements to destroy source information and prevent illegal circulation.
Global service nodes: Branches have been established in Japan, the United States, Germany, Hong Kong and other places, supporting integrated cross-border inventory processing and providing flexible solutions such as consignment sales and consignment sales.
