Inductance is tested at 100kHz, 1.0Vrms, 0Adc. 2. Saturation current, Isat, is the DC current at which the inductance of the component drops by 20% typical at ambient temperature of 25C. 3. Saturation current, Isat, is the DC current at which the inductance of the component drops by 30% typical at ambient temperature of 25C. 4. Heating current, Irms, is the current required to raise the part temperature by approximately 40C. 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 PI134(02) Revised in 12/07 HIGH CURRENT SMT POWER INDUCTORS E & E Magnetic Products Limited RIS1375A Series SCHEMATICS MECHANICAL DIMENSIONS .394 10.00 .118.030 3.000.75 B Max 1375A XXXY (DATE) .157 4.00 .157 4.00 Recommended PAD Layout .516 13.10 Max .295 7.50 Max Gauge Plane or Reference Plane A Part Number A (mm) B (mm) RIS1375A-R20L thru RIS1375A-1R5L .134.012 3.400.30 .543 13.80 Max RIS1375A-2R2L thru RIS1375A-470L .146.012 3.700.30 .555 14.10 Max Notes: 6.
