SR73 Series Current Sense Resistors

SR73 Series Current Sense Resistors

KOA Speer Electronics' SR73 series of low-ohm current sensing chip resistors are available in 0201, 0402, 0603, 0805, 1206, 1210, 2010, and 2512 sizes in resistance values from 24 mΩ up to 10 Ω. Tolerances of ±0.5%, ±1%, 2%, and 5% are offered with TCR as low as ±100 ppm/°C and operating temperature ranges of -55°C to +125°C and -55°C to +150°C.

Low-ohm SR73 resistors are designed for high accuracy and current detection. These resistors are ideal for automotive, telecommunication, and consumer electronics markets in applications such as power supplies, DC-to-DC conversion and AC adaptors, notebook PCs, battery packs, cell phones, and motor circuits.

The SR731E (0402) ~ SR733A (2512) are AEC-Q200 qualified. They are suitable for both flow and reflow soldering.
