Caddock Electronics Inc. has a compact, low-value chip resistor for current-sensing applications that include battery chargers, motor controls, power supplies and other power electronics. Packaged in a 1512 footprint, the CC1512FC chip resistor features non-inductive performance and is available in standard values from 0.01 ohms to 10 ohms.

Featuring low thermal resistance from the resistance film to the terminations, the chip resistor enables designers to take advantage of high-thermal-conductivity substrates such as ceramics and insulated-metal substrates.

Low thermal resistance also allows the device to run cooler on standard glass epoxy-type PCBs such as FR-4, for which it is rated for 0.75W at 700C ambient temperature, the company said.

The unit cost of a CC1512FC-0.050-2% (50 milliohm, 2 percent tolerance) at 10,000 pieces for a North American OEM is 39 cents. Engineering and prototype quantities are available from stock. Delivery is six weeks for production quantities.
