Panasonic ERA-3AEB1073V 107K ohm 0.1% 0.1W 0603 Thin Film Precision Resistor 40 PCS

Panasonic ERA-3AEB1073V high-precision thin-film surface-mount resistor rated 107K ohm, ±0.1% tolerance, 0.1 W, with a ±25 ppm/°C temperature coefficient in the 0603 / 1608 metric package.

This is a high-reliability precision resistor intended for circuits where resistance accuracy and long-term stability matter more than with ordinary general-purpose thick-film parts. Panasonic specifies the ERA-3A series as a thin-film high-reliability resistor family suitable for automotive and other demanding electronics.

The part carries AEC-Q200 qualification and is rated for operation from approximately -55°C to +155°C. Its tight ±0.1% tolerance and low temperature coefficient make it particularly useful in precision analog, instrumentation, measurement, sensing, feedback, reference, and calibration-related circuitry. :chatgpt-content-reference{index="0"}

Lifecycle: ACTIVE.

HISTORICAL BACKGROUND: Panasonic traces its origins to 1918, when Konosuke Matsushita founded the company that later developed into one of Japan’s largest electronics manufacturers. Beyond consumer electronics, Panasonic became a major supplier of passive components, batteries, industrial electronics, automotive components, sensors, and electronic materials.

Thin-film resistor technology was developed for applications requiring tighter resistance tolerances, improved temperature stability, and better long-term consistency than ordinary thick-film chip resistors could provide. Instead of using a relatively coarse resistive paste, thin-film devices use a precisely deposited resistive layer that can be accurately trimmed to the desired value.

The ERA series became Panasonic’s high-reliability precision chip resistor family. The ERA-3A line combines compact 0603 construction with precision values, tight tolerances, low temperature coefficients, and automotive-grade qualification. This made the series useful in measurement electronics, industrial controls, automotive systems, communications equipment, instrumentation, and precision analog circuitry.

The 107K-ohm value is a non-round precision value commonly encountered in resistor-divider networks, amplifier gain-setting circuits, feedback networks, sensor conditioning, references, and other circuits where the exact resistance ratio matters.

The AEC-Q200 qualification associated with this device reflects testing intended for demanding automotive environments, including temperature cycling, humidity exposure, mechanical stress, and long-term reliability requirements. The result is a much higher-grade component than a basic commodity 0603 resistor. :chatgpt-content-reference{index="1"}
