Inductance is tested at 100kHz, 0.1Vrms. 2. Inductance drops 10% typical at Isat. 3. T=30C rise typical at Irms. 4. Operating temperature range: -40C to +85C. 5. Contact EEMPL for RoHS compliant version availability. 6. 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 PI002(06) Revised in 06/07 SMT POWER INDUCTORS E & E Magnetic Products Limited Drum Type, UIS3308 Series, Self-Leaded MECHANICAL DIMENSIONS .510 Max 12.95 .290 7.37 .115 2.92 1 .370 Max 9.40 XYYY 2 .197.005 5.000.13 (DATE) .110 2.79 Recommended PAD Layout .118 3.00 Max Notes: inches 7.
