NOTES:
1.
Actual temperature of the component during system operation(ambient plus 7. Core loss approximation is based on published core data:
temperature rise) must be within the standard operating range.
Core Loss = K1 * (f)1.324 * (ΔB)2.422 in mW
K1 = 71.56 E-4
2. Inductance at Irated is a typical inductance value for the component taken at rated
current.
ΔB = K2 * Vusec in mT
3. The rated current as listed is either the saturation current (@ 25°C) or the heating current
depending on which value is lower.
4. The DCR of the part is measured at an ambient temperature of 20°C 3°C from point a
and b as shown below on the mechanical drawing.
f = switching frequency in MHz
K1 & K2 = core loss factors
V = Voltage across the component in V
Vusec = V * D /f
5. The saturation current, Isat, is the current at which the component inductance drop by
D = Duty cycle
20% (typical) at an ambient temperature of 25°C. This current is determined by placing 8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac
the component in the specified ambient environment and applying a short duration 9. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part
pulse current (to eliminate self-heating effect) to the component.
6. The heating current, Idc, is the DC current required to raise the component temperature
by approximately 40°C. The heating current is determined by mounting the component
number (i.e. PG0871.222NL becomes PG0871.222NLT). Pulse complies to industry
standard tape and reel specification EIA481. The tape and reel for this product has a
width(W=16.0mm), pitch(Po=12.0mm) and depth (Ko=6.8 mm).
on a typical pcb and applying current for 30 minutes. The temperature is measured 10. The core is a conductive material so care should be taken when mounting this
by placing the thermocouple on top of the unit under test. Take note that the
components’ performance varies depending on the system condition. IT is suggested
that the component be tested at the system level, to verify the temperature rise of the
component during system operation.
component over an exposed via or if the voltage across the terminals exceeds
24V. Trickle current through the core material may generate additional losses and
potential overheating. Please contact Pulse to discuss an alternative solution if
required.
