Simple Switcher LM257X

Simple Switcher
LM257X
• Schott Corporation has worked closely with National Semiconductor to biuld a line of premium
inductors designed specifically for use with the Simple Switcher® in DC/DC applications. Excellent
self-shielding makes these inductors ideal for any EMI-sensitive use.
• The gapped core assures stable inductance with varying DC current. These characteristics are
combined with low DC resistance to enable cooler running parts with less ripple.

Electrical Specifications Test Criteria
1. These inductors are designed for operating within a temperature range of -40°C to +130°C.
All electrical characteristics are reported for operating at 25°C.
2. Inductance is measured at 10 kHz, 0.1 Vrms, except for parts #67127030, 040, and 050 which are measured at 10 kHz, 0.2 Vrms.
3. Saturating current is the current at which the inductance is equal to a minimum of 90% of the rated value.
All data is believed to be accurate at time of printing. Schott Corporation reserves the right to make changes without notification.
