Electrical Shunt provides current sensing in reflow ovens.
July 1, 2008 -
Model PVS5 current sensing, surface-mount, wire-wound 5 W electrical shunt is able to dissipate ambient heat associated with reflow ovens. It is manufactured with epoxy resin ratio mixture that can withstand temperatures seen in most standard reflow ovens and which ensures parts do not drift out of close tolerances.

Precision Resistor Co., Inc. Proudly Introduces Our PVS5 Current Sensing Surface Mounted Type Wire Wound Precision 5 Watt Electrical Shunt
Largo, Florida U.S.A., July 1, 2008 - Precision Resistor Company (PRC) has now expanded the capabilities of our vastly succesful PVS series to include the new PVS5 rated to handle nearly twice the amount of power than the previous best part, the PVS3. A long time client & major over seas electronic manufacturer came to us with the desire to improve on the PVS3 so it could handle more power while being able to dissipate the ambient heat associated with reflow ovens. These ovens are commonly used by major manufacturers to attach electrical components to circuit boards. PRC proved up to the task by designing the PVS5 complete with a much stronger epoxy resin ratio mixture that could withstand the temperatures seen in most standard reflow ovens while ensuring the parts do not drift out of close tolerances. In short, we were able to improve on an old part while adhering to the tight electrical specifications associated with the PVS series, allowing one of our most prominent & consistent buyers to have great success in the developing and production of their new application.
PRC is a worldwide custom manufacturer of precision electronic components including precision fixed wirewound resistors, sensors, shunts & compensators for critical applications. Resistors have low EMF of less than 0.3 to 1.5 microvolts per °C with respect to the copper terminals. Features of resistors include lower temperature rise per watt, low TCR & low EMF, repeatable measurements under load, low ohmic values to 1 mW, closer resistance tolerances of plus/minus ±0.005% and operation over a wide temperature span & great stability under load. Additional features include wide variety of shapes & sizes, measurable & predictable voltage/temperature relationship piece-to-piece, high temperature insulation & assorted diameters of pure copper lead sizes. Capabilities also include short & long production runs, customization to buyer specifications & no minimum quantity orders. Industries served include electronics & computer fields among many others. Meets DIN standards & RoHS compliant. N.I.S.T. traceability and tape & reel services are also available.
