The following tables show the range of standard stock size power resistors manufactured for use in electronic, industrial and military applications. Wherever possible, stock type resistors should be specified to assure lowest cost and fastest delivery. When stock type resistors will not meet exact application requirements, "made-to order" resistors can be supplied.

*Standard Tolerance 1 Ohm to Maximum Possible Ohms ± 5%. Below 1 Ohm ± 15%.
Table 5-2 Vitrohm Tubular Resistors.
NOTES: These sizes conform to EIA standards for power wire wound Tubular Type Resistors.
*In selecting high resistance values a reduction in watts rating is necessary due to high voltage limitations.
It is recommended that not more than 495 volts R.M.S. (700 V. Peak) per linear inch length of core be applied. In any event the voltage rating shall not exceed •r watts .. x ohms.
•The maximum possible ohms for tapped resistors must he reduced depending on the length of the resistor and the number of steps.
Vitrohm resistors are also available in adjustable and multi-section forms.
NOTES: These sizes conform to RETMA standards for power wire wound Tubular Type Resistors.
