Rated inductance and Volt-sec are for reference only. 2. Inductance is tested at 100kHz, 0.25Vrms, 0Adc. 3. Inductance drops 30% typical at Isat. 4. Irms for an approximate T of 40C without core loss. It is recommended that the temperature of the part not exceed 125C. 5. Operating temperature range: -40C to +85C. 6. Contact EEMPL for RoHS compliant version availability. 7. 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. 2/F Block A, 94 Tokwawan Road, Kowloon, Hong Kong 1 Tel: (852) 2765 3888 Fax: (852) 2954 3304 PI109(01) Revised in 06/07 SMT POWER INDUCTORS E & E Magnetic Products Limited Drum Type, UISMP2A Series, Self-Leaded MECHANICAL DIMENSIONS .295 Max 7.50 .231 5.88 1 .205 Max 5.20 XYYY (DATE) 2 .295 7.50 .213 5.40 .071 1.80 Max .041 1.05 .079 2.00 Recommended Pad Layout Notes: Weight (in gram) inches Tape & Reel mm with higher precedence in mm. 9.
