LSMS-Series Switchmode Inductors Shielded Surface Mount Features: High DC current bias capability Low radiated field due to shielded design 120° rating (ambient plus rise) Used for output and EMI inductor applications Very low profiles available Compact and thin

The LSMS family of parts are magnetically shielded and are available in all standard Inductance and current values that meets the industry requirements. Precision parts are a low cost alternative or a second source to other major surface mount inductor manufactures. Typical applications for the Power Inductors are switch-mode power supplies, DC/DC converters, form part of RF circuits, RFID systems and can be used as interference suppression components.

How to choose your model:

1. Calculate the energy storage needed based on inductance and current
2. No de-rating needed for ambients up to 80
