Panasonic ERJ-2RKF1402X 14K ohm 1% 0.1W 0402 SMD Thick Film Resistor 80 PCS

Panasonic ERJ-2RKF1402X surface-mount thick-film resistor rated 14K ohm, ±1% tolerance, and approximately 0.1 W in the compact 0402 package.

This is an AEC-Q200 qualified chip resistor intended for reliable use in automotive, industrial, communications, control, and general electronic applications. Its 14K resistance value is useful in biasing networks, pull-up and pull-down circuits, voltage dividers, feedback networks, signal conditioning, and other board-level functions.

Original Mouser packaging identifies Panasonic ERJ-2RKF1402X, 0402 size, 14K ohm, 1% tolerance, and AEC-qualified construction. The label shows country of origin China and date code 2110.

Lifecycle: ACTIVE.

HISTORICAL BACKGROUND: Panasonic traces its origins to 1918, when Konosuke Matsushita founded the business that later became one of Japan’s largest electronics manufacturers. Over the decades, Panasonic developed major product lines in consumer electronics, industrial equipment, automotive systems, batteries, semiconductors, electromechanical devices, and passive components.

The ERJ family became one of Panasonic’s widely used surface-mount resistor lines. Thick-film chip resistors are manufactured by applying a resistive material to a ceramic substrate and trimming it to the required value, producing a compact and economical component suitable for high-volume automated PCB assembly.

The 0402 package became increasingly important as electronics moved toward denser circuit boards and smaller products. At roughly 1.0 x 0.5 mm, 0402 components allow designers to place large numbers of resistors close to ICs and signal paths while minimizing board space.

The ±1% tolerance of this device makes it more precise than older ±5% general-purpose resistor types and suitable for circuits where resistance accuracy affects biasing, gain, logic thresholds, or divider ratios.

AEC-Q200 qualification indicates that the component family has been tested for demanding automotive-style environmental and reliability conditions. This makes it a stronger choice than a basic commodity resistor for applications exposed to temperature variation, vibration, and long service life.
