*Inductance at 0ADC tolerance on indicated part numbers is ±30%; tolerance is ±20% on all other parts. Optional Tape & Reel packaging can
be ordered by adding a "T" suffix to the part number (i.e. PL9401 becomes PL9401T).
NOTES FROM TABLE: (See back page)
Electrical Specifications @ 25°C — Operating Temperature -55°C to +130°C
NOTE: Pin 3 and Pin 4 are for
mechanical connection only.
Height: 0.132 inches (3.35mm) Max
Footprint: 0.410 inches x 0.410 inches (10.4mm x 10.4mm) Max
Inductance Range: 0.67µH to 325µH
Current Rating: up to 7.00A
Notes from Tables
1. Temperature of the component (ambient plus
temperature rise) must be within specified operating
temperature range.
2. The rated current as listed is either the saturation current
or the heating current depending on which value is lower.
3. The saturation current is the current which causes
the inductance to drop to 75% of its initial inductance at
zero bias. This current is determined by placing the
component at room ambient (25°C), and applying a short
duration pulse current (to eliminate self-heating effects) to
the component.
4. The heating current is the DC current, which
causes the temperature of the part to increase by
approximately 40°C. This current is determined by extend-
ing the terminals of the component with 30mm length 28
gauge buss wires and applying the current to the device
for 30 minutes. The temperature is measured by placing
the thermocouple between the winding and the shield.
5. In high volt*time applications, additional heating in the
component can occur due to core losses in the inductor
which may necessitate derating the current in order to limit
the temperature rise of the component. In order to deter-
mine the approximate total loss (or temperature rise) for a
given application, both copper losses and core losses
should be taken into account.
