Precision Products
High Frequency Power		  
  LSMS Switchmode Inductors Shielded Surface Mount
 (This spec sheet is also available in printable format)

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

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° C

Note 1: Inductance measured at 100KHz, 0.1 Vrms, without DC current
Note 2: Rated DC current at which inductance will be decreased by 10% from its initial value or the DC current at a temperature rise of 40° C, whichever is smaller
Note 3: Energy Storage is calculated using the rated current
