Product Overview
The Automotive Grade SMD Power Choke Coil, specifically the MSY4040 Series from COILMX, is a high-reliability magnetic component designed for demanding automotive applications. It features high heat resistance up to 155, excellent vibration resistance due to its integral construction, and a lightweight design suitable for high-density SMT. This choke coil offers high bias current capability with excellent inductance stability, low loss for high efficiency, and a composite structure that minimizes buzz noise. Its magnetic shielding provides excellent resistance to EMI. The coil is AEC-Q200 and RoHS compliant, operating across a wide temperature range of -55 to +155. It is ideal for power line DC-DC conversion applications in power switching, personal computers, and other handheld electronic equipment.
