Entering 299B Inductors
The following table describes the part parameters required for inductors when 299B is the selected calculation model. The 299B model supports all but the Chip subcategory of inductors.
Parameter
Type
Description
Quality Level
Choice List [Parts Count also]
The appropriate quality screening level of the device. Accepted quality levels and values for inductors follow.
A2 = 0.30
B1 = 0.70
B2 = 1.00
C = 4.00
Type
Choice List [Parts Count also]
The type of device. Choices vary by subcategory.
Construction Type
Choice List [Parts Count also]
Required only for the Coil subcategory.
The type of coil construction. Choices are:
Fixed
Variable
Rated Temperature
Choice List
The rated operation temperature of the device. Many different choices are available, including 90, 105, and more.
Temp Rise to Hot Spot
Real (Degrees C)
The temperature rise from the subassembly to the hot spot temperature.
Hot Spot Temperature
Real (Degrees C)
Generally, this field is left at #.# so that the hot spot temperature is calculated as follows:
Hot Spot Temperature = Subassembly Temperature + Temperature Rise to Hot Spot
If you enter a value for this parameter, this value is used in place of a calculated hot spot temperature.
