NOTES:

1. The temperature of component (ambient temperature plus temper-ature

rise) must be within the specified operating temperature range.

2.The maximum current rating is based upon temperature rise of the

component and represents the DC current which will cause a typical

temperature rise of 40°C with no airflow when both one turn windings

connected in parallel.

3. To calculate value of terminating resistor (Rt) use the following formula:

Rt (W) = Vref * N / (Ipeak_primary)

4. The peak flux density of the device must remain below 2000 Gauss. To

calculate the peak flux density for uni-polar current use following formula:

Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 105 / (N * Freq_kHz)

* for bi-polar current applications divide Bpk (as calculated above) by 2.

5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix

to the part number (i.e. PA1005.020NL becomes PA1005.020NLT). Pulse

complies to industry standard tape and reel specification EIA481.

6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suf-

fixed 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 con-

tact Pulse for availability.
