Stackpole has added 0402 and 0603 sizes to its CSRF Series of foil on ceramic carrier current sense chip resistors.
The CSRF0603 is available in resistance values from 5 to 10 milliohms in 1% tolerance and 75 ppm TCR. The CSRF0402 is available in resistance values from 10 milliohms to 15 milliohms in 1% tolerances and 200 ppm TCR. This makes the CSRF well-suited for helping designers downsize all kinds of portable electronics. Lower resistance values allow for sensing higher currents more efficiently and help lower PCB temperatures for lower current levels.
The CSRF is now available in sizes from 0402 up to 2512. Values range from 3 milliohms to 100 milliohms and in tolerances as low as 1%. Pricing varies with size, resistance value, and tolerance, and ranges from $0.07 to $0.30 for the most common values and sizes in full package quantities. Contact Stackpole or one of our franchised distributors for volume pricing. Current lead-times are 8 weeks. Many popular values for the CSRF are in stock or planned for stock.
