High energy Wirewound Axial Terminal / Surface Mount / Heat Sinkable Packaging Ohmite Manufacturings family of High Energy Wirewound Resistors employ special winding tech- niques to maximize the effective joule rating of each resistor. Most wirewound resistors are wound with the objective of meeting the stated power (watt- age) rating and keeping cost low through the use of automatic winding equipment. Typically, manu- facturers will allow substitution of resistance wire, depending on material availability. On tight tolerance wirewounds some type of abrasive adjustment to the resistance wire is often used to maximize production yields. Both of these procedures can adversely affect in this family, Ohmite can publish a fixed joule rat- the joule rating and fusing current of a wirewound ing and fusing current for each part number in the resistor, and this is often the reason that the manu- series. facturer does not publish a fixed joule rating. This technique can be applied to any wirewound Ohmite High Energy Wirewounds are wound so product. In order to provide the broadest selection of as to maintain the tightest possible pitch (space packaging, Ohmite has developed standard offerings between windings) and thereby maximize the mass in three different package types-axial, SMD, and heat of the resistive element. Since no wire substitutions sinkable. Other sizes and types can be quoted on are allowed, and no abrasive adjusting is permitted request, such as tubular power resistors. seRies sPeCiFiCATions Series Type Watts Tolerance Voltage 33Jxxx Axial 3 5% 200 35Jxxx Axial 5 5% 460 30Jxxx Axial 10 5% 1000 825JxxxH Heat Sinkable 25 5% 520 RH3R0DBxxxJ Surface Mount 3 5% 200 Dimensions 33J: 0.593 / 15.1 825JxxxH: 1.938 / 49.23 0.546 / 13.87 in. / mm 35J: 1.000 / 25.4 30J: 1.900 / 46.8 33J: 0.218 / 5.5 35J: 0.343 / 8.7 1.5 / 38.1 30J: 0.406 / 10.3 33J: 20 ga. 35J: 18 ga. 30J: 18 ga.
