The temperature of the component (ambient plus temperature rise) must be within the 4. The standard pin-numbering for this package is indicated in the below mechanical stated operating temperature range. drawing showing pin 1 on the lower right corner and the numbers proceeding clockwise to pin 10 on the upper right corner. 2. For flyback topology applications, it is necessary to ensure that the transformer will not saturate in the application. The peak flux density (Bpk) should remain below 2700Gauss. 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part To calculate the peak flux density use the following formula: number (i.e. (PA3855.001NL becomes PA3855.001NLT). Pulse complies with industry Bpk (Gauss) = K1_Factor * Ipk(A) standard tape and reel specification EIA481. The tape and reel for this product has a width (W=32mm), pitch (Po=24mm) and depth (Ko=13.2mm). 3. In high volt-µsec applications, it is important to calculate the core loss of the transformer. Approximate transformer core loss can be calculated as: CoreLoss (W) = 3.84E-14 * (Freq_kHz)1.63 * (DB_Gauss)2.63 where DB can be calculated as: For Flyback Topology: DB = K1_Factor * DI(A) For Forward Topology: DB = K1_Factor * Volt-µsec 3 pulseelectronics.com P719.D (2/15) Pulse Jack High Frequency Wire Wound Transformers EP13Plus Platforms - SMT Electronics Mechanical PA3855.XXNL/ PA3856.XXNL For More Information Pulse Worldwide Headquarters 12220 World Trade Drive San Diego, CA 92128 U.S.A.
