Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

As new energy vehicles transition to 800V high-voltage platforms and silicon carbide multi-electric drive architectures, automotive-grade inductors, capacitors and resistors have been upgraded from basic components to the "blood vessels of electronic systems". Vishay has set a benchmark for automotive reliability in the field of passive components with its IATF 16949 system and AEC-Q200 certified product matrix. However, production line switching, design changes and order fluctuations have turned a large number of unused Vishay automotive-grade passive components into "frozen capital" on the company's balance sheet. Shenzhen Mingjiada Electronics Co., LTD., relying on 16 years of automotive electronics recycling technology accumulation and a global automotive manufacturer supply chain network, has opened up an efficient recycling channel for Vishay's entire range of passive components for the industrial chain, enabling idle components to regain their technical life and commercial value.

The core backbone of automotive electronics: The irreplaceability of Vishay passive components

Power inductor: The "Metronome" for Electrical Energy conversion

Iron-silicon-aluminum core inductors (such as IHLE-4040) : With a saturation current of up to 48A, they can withstand a di/dt impact of over 100A/μs in 800V OBC on-board chargers, and their temperature rise is 40% lower than that of ferrite.

Metal composite power inductors (IWHP series) : Self-resonant frequency > 10MHz, effectively suppressing the 100 MHZ zip-level ringing noise of SiC MOSFET switches, and increasing the EMC pass rate by 30%.

Automotive-grade capacitors: The "stabilizer" for energy buffering

Wet tantalum capacitors (T59 series) : Withstand extreme temperature cycles ranging from -55 ° C to 125 ° C, ensuring a 20-year zero failure record in airbag ECUs.

MLCC stacked array (VJ HIFREQ) : ESR < 0.5mΩ, absorbs 200A-class load transients in the DC-DC module of the 48V mild mixing system, and suppresses voltage fluctuations within 50mV.

High-energy resistors: The "Safety Valve" for circuit Protection

Metal strip resistor (WSHP series) : With a power density of up to 15W/cm², it achieves an overcurrent response of less than 1μs in IGBT drive circuits.

Current detection resistor (WSLP2726) : Temperature drift ±75ppm/℃, accuracy ±0.5%, providing sub-milliohm sampling reference for BMS battery management systems.

These cutting-edge components are often left idle due to vehicle platform iterations or supply chain redundancy. When Oems switch to silicon carbide electric drive solutions or Tier1 suppliers adjust their production plans, tens of thousands of original factory-sealed Vishay passive components remain in the warehouse, with their value depreciating at a rate of 15% to 20% annually.

2. Mingjiada Recycling System: Dual-driven by scientific assessment and global circulation

Four-dimensional technical Appraisal: Decoding the Value Code of Automotive-grade Components

Mingjiada has established a dedicated evaluation model for automotive electronics to accurately quantify the value of components

Extreme environment simulation test: Cyclically shock 100 times in an oven ranging from -40 ° C to 150 ° C to screen out components that meet the AEC-Q200 Grade 0 standard;

High-frequency characteristic verification: The inductance Q value (> 100@1MHz) and capacitance ESR (< 5mΩ) are measured by a vector network analyzer to ensure the stability of the new energy electric drive system.

Mechanical stress detection: Apply a 50G vibration acceleration to the power inductor to verify the core's resistance to displacement.

Scarcity premium: Due to the surging demand for high-voltage vehicles, the recycling price of components supporting the 800V platform (such as IHLE-4040FD) can reach 70% to 85% of the market price in circulation.

Global ultra-fast response network

Relying on the delivery nodes covering 12 countries, achieve:

Domestic 24-hour response: Factories in the Yangtze River Delta and Pearl River Delta support same-day door-to-door pickup.

Cross-border 72-hour delivery: Through the Hong Kong DDP customs clearance hub, it resolves the bottleneck of export control in Europe and America.

Military-grade protective packaging: shockproof and moisture-proof box + real-time temperature and humidity tracking to ensure zero damage to components.

Compliance traceability guarantee

Source limitation: Only accepts unopened stagnant materials and leftover materials from EOL projects from original equipment manufacturers (Oems) and Tier1 suppliers.

Batch traceability: Verify the original factory MSDS report and IATF 16949 supply chain code to prevent disassembled parts from entering.

3. Mingjiada's core barrier: A dual breakthrough advantage that surpasses traditional recycling

The revolution of capital efficiency

Payment upon inspection: Full payment within 48 hours of arrival (cross-border local currency settlement is supported).

Asset risk hedging

Dynamic premium model: Real-time tracking of the shortage index of 800V platform components (such as a 23% premium rate for automotive-grade MLCC in Q4 2023).
