Panasonic ERJ-2RKF3833X 383K Ohm 1% 1/10W 0402 SMD Thick Film Resistors 70 pcs
$6.95
Lot of 70 genuine Panasonic ERJ-2RKF3833X thick-film surface-mount chip resistors supplied from original Mouser Electronics distributor-labeled stock. These components provide a 383K ohm / 383,000 ohm resistance value with ±1% tolerance and a 0.1W / 1/10W power rating in the miniature 0402 EIA / 1005 metric SMD package.
Panasonic's ERJ-2RK series is a high-reliability general-purpose thick-film resistor family used in communications equipment, industrial electronics, automotive circuitry, test equipment, power-management systems, control boards, and other compact electronic assemblies.
Key specifications include 383K ohm resistance, ±1% tolerance, 0.1W / 1/10W rated power, approximately ±100 ppm/°C temperature coefficient, 50V maximum working voltage, 0402 EIA / 1005 metric package, approximately 1.0 mm x 0.5 mm body dimensions, thick-film construction, -55°C to +155°C operating range, AEC-Q200 qualified family, and surface-mount tape packaging.
The 383K value is useful in circuits requiring moderately high resistance with better accuracy than common 5% parts. Applications can include precision voltage dividers, regulator feedback networks, amplifier and transistor bias circuits, sensing networks, analog interfaces, ADC support circuitry, voltage monitoring, communications electronics, power-management circuitry, and other board-level applications.
Because 383K is less common than values such as 330K, 390K, or 470K, maintaining the exact resistance can be important where resistor ratios establish gain, voltage thresholds, feedback levels, bias points, or measurement accuracy.
LIFECYCLE STATUS: ACTIVE
Current manufacturer and authorized-distributor information identifies Panasonic ERJ-2RKF3833X as an active-production component. It is not currently classified as obsolete, discontinued, EOL, or NRND.
HISTORICAL BACKGROUND:
Panasonic's ERJ family developed during the electronics industry's transition from traditional axial through-hole resistors to automated surface-mount construction. SMD resistors allowed manufacturers to dramatically increase board density while reducing assembly size, lead length, and automated placement time.
The 0402 package represents an advanced stage of this miniaturization. At only approximately 1.0 mm x 0.5 mm, it allows precision resistor networks to be positioned close to processors, converters, regulators, RF support circuits, communications ICs, sensors, and other densely packed devices.
Thick-film chip resistors are manufactured by applying a resistive material to a ceramic substrate and trimming the resistive element until the required resistance is achieved. Protective coatings and metallic end terminations then prepare the device for automated surface-mount soldering.
The exact ERJ-2RKF3833X has documented use in modern high-performance electronics. Maxim Integrated / Analog Devices documentation specifies this Panasonic 383K ohm 1% 0402 resistor in MAX78000 and MAX78002 evaluation hardware, demonstrating use of the exact value in sophisticated processor and power-management support circuitry.
This RF Boneyard stock carries Mouser date code 1734 and represents older unused distributor inventory of a component that remains active today.

Pipeline quantities are informational and may change after arrival, inspection, sorting, testing, or donor teardown.
Compatible Radios / Boards
Suitable for PCB repair, restoration, maintenance, prototyping, and production applications requiring a 383K ohm ±1% thick-film resistor rated at 0.1W / 1/10W in a 0402 / 1005 metric SMD footprint.
Typical applications include precision voltage dividers, regulator feedback circuits, analog networks, ADC support circuitry, transistor bias circuits, voltage sensing, monitoring circuits, power-management boards, communications electronics, RF support circuitry, embedded systems, automotive electronics, industrial controls, instrumentation, test equipment, and general high-density SMD PCB repair.
The exact Panasonic ERJ-2RKF3833X is documented in Maxim Integrated / Analog Devices MAX78000 and MAX78002 evaluation hardware.
Equivalent 383K 0402 resistors from other manufacturers may be suitable when resistance, tolerance, power rating, temperature coefficient, voltage rating, package size, environmental qualification, and circuit requirements are verified.
Do not substitute a nearby value such as 390K solely because the physical package matches. Circuits designed around 383K may depend on the exact resistance ratio or threshold-setting function.
RF Boneyard Bench Notes
Original Mouser Electronics distributor packaging visually inspected and identification verified. Label identifies Mouser number 667-ERJ-2RKF3833X, Panasonic part number ERJ-2RKF3833X, 383K ohm resistance, 0402 SMD thick-film construction, RoHS compliance, China country of origin, and date code 1734. Original package quantity was 100 pieces; current RF Boneyard inventory is 70 pieces. Components remain in carrier-tape stock and have not been individually resistance-tested due to the miniature 0402 package and lot quantity. Lifecycle research confirms the exact part remains active production.
