Introducing the Eaton Electronics HCMA0503-R75-R, a high-performance automotive-grade fixed inductor designed for demanding electronic applications. Manufactured in China by Eaton Electronics, this surface-mount component offers reliable high-current inductance with low core losses and minimal electromagnetic interference (EMI).
Product Features
High current carrying capacity up to 11.3A RMS and 9.7A saturation current
Inductance value of 750nH with ±20% tolerance
Low DCR of approximately 8.5mΩ at 20°C for efficient power management
Magnetically shielded design to reduce EMI
Frequency range up to 1 MHz suitable for automotive and high-frequency applications
Iron powder core material ensuring stability and durability
RoHS compliant, halogen-free, and lead-free
Package Type: Reel, surface-mount in a compact 5.5mm x 5.3mm footprint with a height of 3.0mm
I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
