UISH3C2M-1R0, UISH3C2M-2R2, UISH3C2M-4R7 and UISH3C2K-100 are low DCR type. 2. Test frequency is specified for testing the inductance. 3. Operating temperature range: -40C to +85C. 4. Contact EEMPL for RoHS compliant version availability. 5. 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 PI044(01) Revised in 06/07 SMT POWER INDUCTORS E & E Magnetic Products Limited Drum Type, UISH3C Series, Self-Leaded MECHANICAL DIMENSIONS .098.008 2.500.20 .217 5.50 .098.008 2.500.20 .079 2.00 .079.008 2.000.20 .039 1.00 .098.008 2.500.20 .126.012 3.200.30 .039 1.00 .051 1.30 .039 1.00 Recommended Pad Layout .035.012 0.900.30 .035.012 0.900.30 .051.008 1.300.20 Notes: 6.
