800A resistor gets tapped holes for mounting and connections

Vishay has added tap holes in some of its high-current shunt resistors to help PCB and wire installation.

with

These are 36W battery shunt resistors with M3 and M4 tap holes (near the center of the photo). The resistance is 85 x 18 x 3mm

With resistance values ​​as low as 50µΩ, Vishay regards them as a more accurate and low-cost alternative to Hall effect sensing, "and their threaded holes facilitate PCB mounting, provide additional vibration support and provide mounting voltage sensing guides. The position of the feet," the company.

The temperature coefficient of the solid metal manganese copper alloy resistance element is ±20ppm/°C, and the solder connection between the terminal and the element can provide up to 848A of continuous current (50, 100, 125 and 250µΩ). Depends on resistance).

The inductance is <5 nH, the thermal electromotive force can be as low as <3µV/°C, and the operating temperature range is -65 to +170°C.

These devices comply with RoHS, halogen-free and Vishay Green requirements.

The product is expected to be used in gasoline, diesel, hybrid, electric cars and trucks, as well as electric forklifts, UPS systems and other heavy industrial applications.

Samples and mass production are now available, and the lead time for large orders is 10 to 12 weeks.
