1. The temperature of the component (ambient plus temperature rise) must be within
the stated operating temperature range.
2. The above transformers and inductors have been tested and approved by Pulse’s
power IC partners and are sited in the appropriate datasheet or evaluation board
documentation at these companies. To determine which IC and IC partners are
matched with the above Pulse part numbers please consult the IC Cross Reference on
the Pulse website.
3. 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.
To calculate the peak density, use the following formula
Bpk (Gauss) = K1_Factor * Ipk (A)
4. In high volt-sec applications, it is important to calculate the core loss of the trans-
former.
Approximate transformer core loss can be calculated as:
CoreLoss (W) = 2.5E-14 * (Freq_kHz)1.63 * (ΔB_Gauss)2.63
where ΔB can be calculated as:
For Flyback Topology: ΔB = K1_Factor * ΔI(A)
For Forward Topology: ΔB = K1_Factor * Volt-µsec
5. The standard pin-numbering for this package is indicated in the below mechanical
drawing showing pin 1 on the lower right corner and the numbers proceeding clock
wise to pin 10 on the upper right corner. However, for those parts that are indicated
as having an alternate pinout, pin 1 is in the lower left corner and the numbers
proceed counter-clockwise to pin 10 in the upper left corner. Refer to the alternate
mechanical drawing for further details.
6. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part
number (i.e. PA1136NL becomes PA1136NLT). Pulse complies with industry standard
tape and reel specification EIA481. The tape and reel for this product has a width
(W=32mm), pitch (Po=24mm) an depth (Ko=13.2mm).
7. The “NL” sux indicates an RoHS-compliant part number. Non-NL suxed parts are
not necessarily RoHS compliant, but are electrically and mechanically equivalent to
NL versions. If a part number does not have the “NL” sux, but an RoHS compliant
version is required, please contact Pulse for availability.
