Ohmite WH/WN Miniature Molded Wirewound Resistors
Ohmite WH/WN Miniature Molded Wirewound Resistors feature a resistance range of 0.10kΩ to 50KΩ, an epoxy molding compound encapsulation, and are designed to meet MIL-R-26F and MIL-STD-202 standard requirements. The WH components are the precision series while the WN devices are the Aryton Perry Winding Non-Inductive series with a <1nH inductance at 1MHz. These resistors are ideal for precision applications where costs are sensitive, such as office and lab environments.
