WG73 Series Wide Terminal Surge Current Flat Chip

KOA Speer Electronics' WG73 wide terminal type surge current flat chip resistor is superior to the WK73 in pulse withstanding voltage. The WG73, in a 1020 package with a 1 Watt power rating, offers a TCR of +100 ppm/°C with a resistance range of 560 mΩ to 1 KΩ. With a standard tolerance of ±10% and +20%, the anti-surge WG73 features a wide operating temperature range of -55°C to +155°C. The WG73 is also AEC-Q200 qualified.

The WG73 chip resistor features wide side electrodes which provide better heat dissipation and smaller size compared to other standard chip resistors. This wide terminal resistor is designed for high accuracy and current detection, making it ideal for automotive, telecommunication, and consumer electronics markets in applications such as power supplies, DC-to-DC conversion and AC adaptors, automotive ECUs, and motor circuits.
