SMT POWER INDUCTORS
E & E Magnetic Products Limited
Toroid Type
Surface mount design that can be used as single or
coupled inductors or 1:1 transformers that provide
isolation between two windings
Higher cost versions are designed with high frequency,
low loss material which allows maximum power density
with minimum core loss
Lower cost versions incorporate powdered iron cores
and deliver frequency responses
Current rated from 0.22 to 7.9Adc
Isolation voltage: 300V
Operating temperature -40°C to +125°C
RoHS compliant

Notes:
1. Inductance is measured at 100kHz, 0.25Vrms.
2. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the operating
temperature under worst case operating conditions. Circuit design, component placement, PWB trace size and
thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified
in the end application.
