The VPG Foil Resistors product group of Vishay Precision Group announced the global market launch of the Alpha Electronics FNP Series, a family of high-power precision shunt resistors.
Design of the Alpha Electronics FNP Series incorporates VPG’s own proprietary Bulk Metal Foil technology for a low temperature coefficient of resistance (TCR) down to 0±1 ppm/°C, depending upon selected model. Integration of a Pt100 sensor within the FNP Series allows for accurate onboard temperature monitoring of the resistive element, with added performance stability. Units feature a maximum handling capability of 500W rated power, with no standard resistance value. An integral copper plate helps the FNP Series to achieve an improved thermal resistance specification of 0.1°C/W (0.3°C/W standard), while a resistance tolerance of 0.05% ensures minimized energy consumption. Standard resistance values of the FNP Series range from 0.001 ohm to 1 ohm, with improved maximum ambient temperature to +125°C (from +85°C) for conventional models.
