Shielded Drum Core Inductor
PA4330.XXXNLT Series
Pulse Jack
E l e c t r o n i c s
Height: 1.0mm Max
Footprint: 2.2mm x 1.8mm Max
Current Rating: up to 3.1A
Inductance Range: 0.47uH to 2.2uH
Shielded magnetic circuit reduces leakage flux, Fe base metal
core enables high saturation and metalized core termination
results in excellent shock resistance
Electrical Specifications @ 25°C — Operating Temperature -40°C to 125°C
1. Actual temperature of the component during system operation (ambient plus temperature rise)
must be within the standard operating range.
2. The rated current as listed is either the saturation current (20°C) or the heating current (40°C Rise)
depending on which value is lower.
3. The saturation current is the current at which the initial inductance drops approximately 30% at the
stated ambient temperature. This current is determined by placing the component in the specified
ambient environment and applying a short duration pulse current (to eliminate self-heating effect)
to the component.
4. The heating current is the DC current required to raise the component temperature by approximately
20°C or 40°C. Take note that the components’ performance varies depending on the system condi-
tions. It is suggested that the component be tested at the system level, to verify the temperature
rise of the component during system operation.
5. Maximum voltage across terminals to be limited to <25Vdc.
