High Frequency Wire Wound Transformers
EFD15 Platforms - SMT
Notes
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
flux density use the following formula:
Bpk (Gauss) = K1_Factor * Ipk(A)
1.
4. 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) = 4.6E-14 * (Freq_kHz)
1.63
* (DB_Gauss)
2.63
where
DB
can be calculated as:
For Flyback Topology:
DB
= K1_Factor *
D(A)
For Forward Topology:
DB
= K1_Factor * Volt-µsec
5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e.
PA0476NL becomes PA0476NLT). Pulse complies with industry standard tape and reel specification
EIA481. The tape and reel for this product has a width (W=44mm), pitch (Po=32mm) and depth
(Ko=11.78mm).
6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not neces-
sarily 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.

C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
