Lot of 40 genuine Panasonic ERJ-3EKF6811V surface-mount thick-film chip resistors from original distributor-labeled inventory. These resistors provide a precision 6.81K ohm resistance value with ±1% tolerance in the widely used 0603 EIA / 1608 metric SMD package.

Panasonic's ERJ-3EK series is a general-purpose thick-film chip resistor family engineered for reliable surface-mount use in electronic equipment ranging from communications and industrial control hardware to automotive electronics, power supplies, test equipment, audio circuitry, and general PCB assemblies.

LIFECYCLE STATUS: ACTIVE

Current Panasonic and Digi-Key records continue to identify ERJ-3EKF6811V as an active-production component. It is not presently classified as obsolete, discontinued, EOL, or NRND. Digi-Key currently lists substantial inventory of the exact part.

Key manufacturer specifications include:

6.81K ohm / 6810 ohm resistance
±1% resistance tolerance
0.1W / 1/10W rated power
±100 ppm/°C temperature coefficient
0603 EIA / 1608 metric package
Approximately 1.60 mm x 0.80 mm body size
Approximately 0.55 mm maximum seated height
-55°C to +155°C operating temperature range
Thick-film resistive construction
Two-terminal surface-mount package
AEC-Q200 automotive-qualified family
Paper tape packaging

Panasonic's current specification confirms 6,810 ohms, 1% tolerance, 0.1W power rating, 1.6 x 0.8 mm dimensions, and ±100 ppm/°C temperature coefficient for this exact model.

The 6.81K value is part of the standard precision resistance progression commonly encountered in bias networks, voltage dividers, feedback circuits, amplifier support stages, regulator circuits, analog interfaces, sensing circuits, control boards, communications equipment, and other circuitry requiring a tighter value than common 5% resistor series provide.

Thick-film chip resistors are manufactured by depositing a resistive material onto a ceramic substrate, trimming the resistive element to the required value, and protecting the finished element with insulating coatings. Metal terminations at each end provide the solder connection to the PCB.

The compact 0603 format allows these resistors to be mounted in high-density electronic assemblies while remaining one of the more common SMD package sizes encountered during board-level repair.

HISTORICAL BACKGROUND:

Panasonic has been a major supplier of passive electronic components for decades, supporting the transition of electronics manufacturing from large leaded components to compact automated surface-mount construction.

The ERJ family became one of Panasonic's major chip-resistor product groups, offering numerous resistance values, tolerances, package sizes, power ratings, and specialized versions for different circuit requirements.

The 0603 package became especially widespread as manufacturers sought to increase component density without moving immediately to extremely small packages that are more difficult to assemble and service. Measuring approximately 1.6 mm x 0.8 mm, the 0603 format is significantly smaller than traditional through-hole resistors yet remains common in radios, communications equipment, industrial controls, test equipment, consumer electronics, automotive modules, and modern power-management circuitry.

Values such as 6.81K ohms became increasingly useful as 1% resistor networks replaced broader-tolerance 5% designs in circuits requiring improved voltage-divider accuracy, bias repeatability, gain setting, feedback control, and production consistency.

The ERJ-3EK family remains relevant because the same basic component can be used in both repair work and present-day manufacturing. For a repair technician, having the exact resistance, tolerance, package, and power rating available can be important when restoring a board to its original electrical configuration instead of installing an approximate replacement.

Panasonic continues to manufacture ERJ-3EKF6811V today. Digi-Key identifies it as an ACTIVE 6.81K ohm ±1%, 0.1W, AEC-Q200 thick-film resistor with an operating range of -55°C to +155°C.
