Lot of 80 genuine Panasonic ERJ-PA2F10R0X precision surface-mount resistors. These are 10 ohm ±1% thick-film chip resistors from Panasonic's ERJ-PA2 anti-surge high-power series in the very compact 0402 / 1005 metric package.

The ERJ-PA2F10R0X is designed for applications where a standard miniature chip resistor may not provide sufficient pulse, surge, or electrostatic-discharge robustness. Panasonic specifies the ERJ-PA2 series for high-reliability circuitry and uses a thick-film resistive element with a construction optimized for improved surge performance.

Key manufacturer specifications include 10 ohm resistance, ±1% tolerance, ±100 ppm/K temperature coefficient, 0402 EIA / 1005 metric package, and an operating temperature range extending from approximately -55°C to +155°C. Panasonic's current product data specifies a 0.25 W rated power for this part. The series is also AEC-Q200 qualified for automotive-grade applications and is suitable for demanding industrial and consumer electronic designs.

These resistors are supplied from Panasonic tape stock. The original distributor label identifies Mouser number 667-ERJ-PA2F10R0X, Panasonic manufacturer number ERJ-PA2F10R0X, 0402 size, 1% tolerance, 10 ohm value, Japan country of origin, and date code 2126.

HISTORICAL BACKGROUND:

Panasonic developed the ERJ family as a broad range of compact thick-film chip resistors for the increasingly dense surface-mount electronics market. As electronic assemblies became smaller while pulse loads, switching transients, and ESD requirements increased, specialized anti-surge resistor families such as the ERJ-PA series became important for providing greater reliability than conventional general-purpose chip resistors of similar physical size.

The ERJ-PA2 series is especially notable because it brings enhanced pulse and surge capability into the tiny 0402 footprint. Panasonic promotes the family for automotive, transportation, industrial electronics, and consumer electronics where board space is limited but electrical reliability remains important. Panasonic literature for the series also cites high ESD resistance, including approximately 3 kV ESD capability for the ERJ-PA2 family.

Unlike many vintage electronic components stocked by RF Boneyard, ERJ-PA2F10R0X remains an ACTIVE Panasonic production part and is not currently classified as obsolete or discontinued. This makes the lot useful both for restoration work involving existing surface-mount assemblies and for ongoing repair, prototyping, and production requirements.
