Temperature rise is 50C in typical buck or boost circuits at 250kHz and with the refer- 10. The temperature of the component (ambient plus temperature rise) must be within ence ET applieed to the inductor. the stated operating temperature range. 2. Total loss in the inductor is 380mW for 50C temperature rise above ambient. 3. To estimate temperature rise in a given applicatoin, determine copper and core losses, divide by 380 and multiply by 50. 2 4. For the copper loss (mW), calculate IDC * RN. 5. For core loss (mW), using frequency (f in Hertz) and operating flux density (B in -18 2.7 2.04 Gauss), calculate 6.11 * 10 * B * f 6. For flux density (B in Gauss), calculate ET (V-sec) for the application, divide by ET 100 from the table, and multiply by 100.Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H1 from the table IDC of the application. 7. Limit the DC bias (H) to 46 orsteds. Calculate H by multiplying H from the table by I 1 DC of the application. 8. Optional Tape & Reel application packaging can be ordered by adding a T suffix to the part number (i.e. P0144NL becomes P0144NLT). Pulse complies to industry standard tape and reel specification EIA481. 9. The NL suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the NL suffix, but an RoHS compliant version is required, please contact Pulse for availability. 1 power.pulseelectronics.com SPM2007 41 (03/19) SMT Power Inductors Toroid - Bobcat Series Schematic Mechanical 4 1 PXXXXXNL 2 3 1:1 1% .060 2X 1,52 .500 .470 MAX 12,70 11,94 .400 10,16 R Suggested Pad Layout Weight ...............................1.5grams Tape & Reel ........................500/reel .215 Tube ......................................40/tube MAX 5,46 .Inches Dimensions: mm .390 Unless otherwise specified, 9,91 ..010 .005/0,13 all tolerances are: 0,25 .500 MAX 4 SURFACES 12,70 For More Information Pulse Worldwide Headquarters Pulse Europe Pulse China Headquarters Pulse North China Pulse South Asia Pulse North Asia 15255 Innovation Drive Ste 100 Pulse Electronics GmbH Pulse Electronics (ShenZhen) CO., LTD 3 Fraser Street 0428 1F., No.111 Xiyuan Road Room 2704/2705 San Diego, CA 92128 Am Rottland 12 D708, Shenzhen Academy of DUO Tower Zhongli District Super Ocean Finance Ctr.
