Vishay Precision Group (VPG) Powertron announced that it will expand its S-Line precision foil current sensing resistors with five new SHR series devices. The German-made SHR 4-8065, SHR 4-80110, SHR 4-80216, SHR 4-80320 and SHR 4-80370 are available in various anodized aluminum packaging sizes, and have a low TCR / K of ± 2 ppm, with power ratings up to 2500W.
RoHS-compliant SHR 4-8065, SHR 4-80110, SHR 4-80216, SHR 4-80320 and SHR 4-80370 can provide 0.1% load stability for up to 0.1 hours, providing high precision in industry And reliable current sensing power supply, digital multimeter, current control system, medical equipment, solar and wind energy inverter and AC / DC converter, as well as battery charger and electric vehicle test equipment and other systems.
Resistors provide a wide range of power ratings-from 24W in free air to 2500W when installed on a radiator-resistance values are low from 0.005ohm to 300ohm, and the tolerance range is ± 0.1%. The maximum current of the device is up to 60A (higher values and currents are available upon request), very low inductance of less than 50nh, thermal EMF of less than 1 µV / C, and temperature range of -40C to + 130C.
Kaitron Karstensen, Managing Director of Powertron, said: "Choosing precision resistors will have a profound impact on system performance." For measuring instruments, semiconductor test equipment, consumer electronics and other applications that require stability, reliability and accuracy, our SHR series The foil current detection resistor provides an ideal solution.
