Entering 217Plus Resistors

Windchill Risk and Reliability Desktop Help > Windchill Prediction > Part Parameters Required for Predictions > 217Plus Part Parameters > Entering 217Plus Resistors

The following table describes the part parameters required for resistors when 217Plus is the selected calculation model. This model supports all but the following subcategories of resistors:

• Glass Glazed, Var

• Organic Solid, Var

• Surface Mount

Parameter

Type

Description

Year of Manufacture

Integer

The four-digit year in which the device was manufactured (such as 1998 or 2004). The default is the current year.

While this field is used to determine the Growth factor (Pi G) for other parts, it does not affect the Growth factor for resistors. This is because a beta factor of 0 is used for all resistors. When the G factor is raised to the beta power, the result is always 1.

Variable

Checkbox

Required only for the General subcategory.

Indicates if the general resistor is a variable type.

Rated Power

Real (Watts)

The rated power of the device.

Temperature Rise

Case Temp Override

Real (Degrees C)

The 217Plus model for resistors does not provide for temperature changes. To meet customer demands for a way to make temperature adjustments, Temperature Rise and Case Temp Override are provided. For more information, see Basic Temperature Parameters.
