Original Digi-Key packaging identifies Panasonic Electronic Components as the manufacturer and ERJ-2RKF2493X as the manufacturer part number.
HISTORICAL BACKGROUND:
Panasonic's ERJ series became widely used as electronic manufacturing transitioned toward compact automated surface-mount assembly. These thick film chip resistors are found throughout communications equipment, industrial electronics, automotive systems, instrumentation, computing hardware, control circuits, consumer electronics, and embedded systems.
The 0402 package provides substantial PCB space savings while maintaining dependable electrical performance for low-power circuitry. Precision 1% resistor values such as 249K ohm are commonly selected for feedback networks, voltage dividers, amplifier biasing, sensing circuits, timing networks, control loops, and other applications where tighter resistance accuracy is desirable.
The ERJ-2RKF2493X remains an active production component and carries AEC-Q200 qualification for automotive-grade applications.
