Full Description & History

Genuine KOA Speer RK73H2ATTD3740F precision thick-film surface-mount chip resistors featuring a 374 ohm resistance value, 1% tolerance, and 0.25W (1/4 watt) power rating. These compact 0805 (2012 metric) resistors belong to KOA's RK73H resistor family, designed for electronic circuits requiring consistent resistance characteristics, compact dimensions, and dependable performance.

The 374 ohm resistance value belongs to the E96 precision resistor series and is useful in voltage dividers, current-limiting networks, amplifier bias circuits, signal conditioning, feedback circuits, industrial controls, communications electronics, and general component-level repair.

These resistors feature thick-film resistive elements on ceramic substrates with protective coatings and solderable terminations suitable for automated surface-mount assembly.

LIFECYCLE: NOT VERIFIED

\- HISTORICAL BACKGROUND: KOA Corporation is a Japanese electronic component manufacturer with an established history in resistor production and precision passive components. The company developed an extensive range of fixed resistors, including carbon-film, metal-film, wirewound, thick-film, and specialized surface-mount resistor technologies for industrial and commercial electronics.

  KOA Speer Electronics serves the North American electronics market with resistor products originating from KOA's manufacturing and engineering operations. The company supplies components for communications equipment, industrial controls, automotive electronics, consumer devices, power management systems, and electronic manufacturing.

  During the late twentieth century, electronic manufacturers increasingly adopted surface-mount technology as printed circuit boards became smaller and automated assembly processes replaced traditional manual insertion of leaded components.

  Thick-film chip resistors became important in this transition because they could be manufactured in compact standardized dimensions while offering consistent resistance values, economical production, and reliable operation across a wide variety of circuit applications.

  The KOA RK73 series was developed as a family of general-purpose and precision thick-film surface-mount resistors. Its standardized chip sizes allowed engineers to incorporate resistor networks and individual fixed resistors into densely populated printed circuit boards.

  The RK73H family provides precision resistance tolerance, temperature stability, and higher power ratings for selected package sizes. These characteristics make the series suitable for applications requiring dependable electrical behavior in industrial, automotive, and general electronic systems.

  The RK73H2ATTD3740F represents the 0805 package version with a 374 ohm resistance value, 1% tolerance, and 0.25W power rating. Its precision E96 resistance value allows circuit designers and repair technicians to select a more specific resistance than the commonly encountered E12 or E24 standard values.

  The RK73H series remains relevant to electronics manufacturing and maintenance, particularly where existing equipment requires exact-value replacement components rather than approximate resistance substitutions.
