Notes: 1. Actual temperature of the component during system operation (ambient plus
temperature rise) must be within the standard operating range.
2. The saturation current is the current at which the initial inductance drops
approximately 30% at the stated ambient temperature. This current is determined
by placing the compnent in the specified ambient environment and applying a short
duration pulse current (to eliminate self-heating effect) to the component.
3. The rated current is the DC current required to raise the component temperature by approximately 40�C. Take note that the components’ performance varies depending on the system condition. It is suggested that the component be tested at the system
level, to verify the temperature rise of the component during system operation. 4. The part temperature (ambient+temp rise) should not exceed 125�C under worst
case operating conditions. Circuit design, PCB trace size and thickness, airflow and
other cooling provisions all affect the part temperature. Part temperature should be
verified in the end application. 5. Please note that the inductance tolerance of all parts are ±20%, except .151NLT which
is ±30%. 6. Parts shown in bold are standard catalog parts and are available through sample
stock and distribution. Parts in lighter font are available but are not necessarily held in sample stock or distribution and lead times may be longer. Please contact Pulse for availablity. 7. The PM prefix parts are AEC-Q200 qualified and has full automotive IATF16949 certification. The mechanical dimensions are 100% tested in production but do not necessarily meet a product capability index (Cpk) 1.33 and therefore may not strictly conform to PPAP. 8. Special Characteistic
