Vehicle grade CD series patch wound inductor with wide temperature range AEC-Q200 certification for automotive electronic power supply

Description :

  Yuzhixin's CD series patch wound inductors are passive components designed specifically for automotive electronics and high reliability industrial applications. This series of products mainly solves the problems of filtering, energy storage, and anti-interference in the power circuit under harsh working conditions, ensuring the stable operation of the car headlight drive, central control power supply, and new energy electronic control system. Its core advantage lies in its compliance with AEC-Q200 automotive grade standards, which can maintain stable performance in a wide temperature range of -40 ℃ to 125 ℃, effectively cope with the high current impact at the moment of car startup and long-term high-temperature working environment, and is a key basic component for improving the reliability of the vehicle's electronic system.

  This patch wound inductor is made of high-purity copper wire wound on a high-quality magnetic core, with rigorous craftsmanship, excellent high-frequency characteristics, and low direct current resistance (DCR). During the production and manufacturing process, we strictly adhere to the automotive grade quality management system to ensure product consistency and yield. Conventional specifications such as CD32, CD43, CD54, CD75, etc. cover application requirements from low power to medium power. The magnetic shielding structure design effectively reduces electromagnetic interference (EMI) and prevents it from affecting sensitive circuits in the surrounding area. The product has passed strict temperature resistance, moisture resistance, and mechanical strength tests, meeting the stringent requirements of the automotive industry for long service life and low failure efficiency of components.

  When selecting, it is necessary to choose based on the specific application scenario's current size, space limitations, and inductance requirements. CD32 and CD43 have small volumes and are suitable for compact car USB charging ports or small sensor power supply circuits; CD54 and CD75 are larger in size and have higher saturation current, making them more suitable for driving LED headlights, central control large screen power modules, and low-power electronic control units for new energy BMS. Compared with ordinary consumer grade inductors, Yuzhixin's CD series patch wound inductors perform better in temperature rise control and long-term aging stability. If the application environment involves severe vibration or extreme temperature, it is necessary to prioritize the use of AEC-Q200 certified models to avoid early failure risks.

  It is recommended to use an SMT surface mount machine for automated operations during installation. Please note that the reflow soldering temperature curve should comply with lead-free process standards to avoid thermal shock causing magnetic core cracks or solder joint virtual soldering. In daily maintenance and troubleshooting, if excessive power output ripple or abnormal inductance heating is found, the focus should be on checking whether the inductance is saturated or the pins are oxidized. This series of products is readily available in stock and supports customized sensing values, making it easy to quickly sample during the research and development stage and flexibly adjust during the mass production stage. Reasonable layout of PCB wiring can reduce the influence of parasitic parameters, further leveraging the high-frequency and low loss advantages of Yuzhixin's CD series chip wound inductors, and extending the service life of terminal equipment.
