YAGEO RC0603FR-07100KL 100K ohm 1% 1/10W 0603 SMD Resistor 475 PCS PACK

Original Mouser Electronics distributor package containing 475 YAGEO RC0603FR-07100KL thick-film surface-mount resistors. Each resistor is rated 100K ohm with ±1% tolerance and 0.1W / 1/10W power rating in the compact EIA 0603 / metric 1608 package.

This listing is for the complete 475-piece package as one sellable unit. The original Mouser label identifies Mouser part number 603-RC0603FR-07100KL and describes the components as 100K ohm 1% YAGEO thick-film SMD resistors. The package is also marked RoHS compliant.

The 100K ohm value is widely used in bias networks, pull-up and pull-down circuits, voltage dividers, feedback networks, sensing circuits, timing networks, signal conditioning, and general digital or analog PCB assemblies. The ±1% tolerance makes these suitable for applications requiring tighter resistance control than standard 5% general-purpose parts.

HISTORICAL BACKGROUND:
Thick-film chip resistors became one of the fundamental building blocks of modern surface-mount electronics as manufacturers transitioned away from larger axial leaded resistors during the growth of automated PCB assembly. By printing a resistive film onto a ceramic substrate and trimming it to the required value, manufacturers were able to produce compact, repeatable resistors in enormous volumes while maintaining consistent electrical performance.

The 0603 package became particularly common during the expansion of compact communications equipment, computers, industrial controls, consumer electronics, test equipment, and embedded systems. It offered a practical balance between small PCB footprint and straightforward automated assembly.

YAGEO grew into one of the major global passive-component manufacturers supplying chip resistors, capacitors, and related components for high-volume electronics production. The RC0603 family represents the type of general-purpose thick-film resistor that became standard across countless electronic designs. A 100K ohm ±1% version remains useful for both new construction and repair work where an exact resistance value and compact 0603 footprint are required.
