PGT6465NL變壓器的開關(guān)轉(zhuǎn)換器SMPS變壓器規(guī)格書PDF中文資料

1. Storage Temperature: -40°C to 125°C

2. The temperature of the component (ambient plus temperature rise) must be within

the stated operating temperature range.

3. Pri/Lk. Inductance value is measured at 100Khz/0.1Vrms.

4. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part

number (i.e. (PGT6465NL becomes PGT6465NLT). Pulse complies with industry

standard tape and reel specification EIA481.

Notes:

5. 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)

6. 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 * (ΔB_Gauss)2.63

where ΔB can be calculated as:

For Flyback Topology: ΔB = K1_Factor * Δ(A)
