VSMD1505

VSMD1505 Vishay Foil Resistors SURFACE MOUNT Bulk Metal® Foil Technology Miniature, Ultimate Tracking Surface Mount Divider FEATURES Product may not be to scale • • • • • • • • This extremely small surface mount voltage divider made of Bulk Metal® Foil technology offers the ultimate in tracking and ultimate in ratio stability. Additionally Bulk Metal® Foil has an extremely low absolute temperature coefficient of resistance so the temperature differential caused by power unbalances associated with large ratios will not adversely affect the tracking specification. The absence of noise generation by the resistor make it the ultimate component.
