KOA Speer Electronics introduces its new line of
current sensing surface mount resistors designed for lesser thermal
expansion/contraction, allowing for fewer mismatches and/or separations
between the part and the PCB. The unique open-center shapes of the
LR72A/B/C series provide cooler operation as the flexible leads also
allow for thermal expansion and aid in alleviating stress to the
component. KOA Speer current sensing resistors minimize current
interference. The LR72 A/B/C series resistors offer a standard tolerance of ±5%, an inductance value of under 10nH and standard resistance ratings as low as 0.002 Ohms. Types A and B feature a TCR of ±100ppm/°C and power ratings of 1/2W @ 25°C and 1/4 W @ 25°C respectively. Type C features a TCR of ±350ppm/°C and power ratings of 1W @ 70°C and 2W @ 25°C. KOA Speer LR72 A/B/C series resistors are flameproof and designed with 60/40 plate pads suitable for flow and reflow soldering.
KOA Speer LR72 A/B/C series resistors may be used in current
sensing, low inductance, feedback, surge and pulse, and AC applications
(consult KOA Speer factory regarding AC use).
