$8.95

Lot of 85 genuine Panasonic ERJ-6GEYK186V high-value thick-film surface-mount chip resistors supplied from original distributor-labeled inventory.

These resistors provide an unusually high resistance value of 18 megohms / 18M ohms with ±10% tolerance and a 0.125W / 1/8W power rating in the common 0805 EIA / 2012 metric SMD package.

The ERJ-6GEYK186V belongs to Panasonic's ERJ-6G thick-film chip-resistor family and was designed for reliable surface-mount use, including automotive-qualified applications.

Key specifications include:

18M ohm / 18,000,000 ohm resistance
±10% resistance tolerance
0.125W / 1/8W rated power
0805 EIA / 2012 metric SMD package
Approximately 2.00 mm x 1.25 mm body dimensions
Approximately 0.70 mm maximum height
-55°C to +155°C operating temperature range
-400 / +150 ppm/°C temperature coefficient
Thick-film resistive construction
Two-terminal surface-mount package
AEC-Q200 automotive-qualified series
RoHS-compliant construction
Tape-and-reel / carrier-tape packaging

The 18M-ohm resistance value places this component at the high-resistance end of ordinary board-level resistor applications. High-megohm resistors are commonly used where only extremely small currents should flow, including high-impedance sensing networks, voltage-monitoring circuits, bleeder and discharge networks, input-bias paths, detector circuitry, measurement equipment, high-voltage divider networks, leakage-sensitive circuits, timing networks, and other specialized analog applications.

Because an 18M-ohm resistor passes only a very small amount of current under normal conditions, contamination, PCB leakage, humidity, flux residue, and measurement-equipment input resistance can become significant factors in circuits using values this high. Repair technicians should therefore maintain clean board surfaces and verify the original circuit requirements when servicing high-impedance networks.

Panasonic's ERJ thick-film construction uses a ceramic substrate carrying the resistive element, protective layers, and metallic end terminations. The resistive element is adjusted during manufacturing to achieve the specified nominal resistance and tolerance.

The ERJ-6GEYK186V uses the widely adopted 0805 footprint, providing a useful balance between compact PCB area, automated assembly, and practical handling during repair.

LIFECYCLE STATUS: OBSOLETE

Panasonic ERJ-6GEYK186V is now an obsolete / discontinued manufacturer part number.

Current authorized-distributor lifecycle information identifies the part as Obsolete and states that it is no longer manufactured. Remaining distributor inventory represents residual stock and will not be replenished after depletion.

This lifecycle status makes original unused ERJ-6GEYK186V stock increasingly relevant for technicians repairing equipment designed around the exact Panasonic part number, especially when maintaining original component specifications is preferred.

HISTORICAL BACKGROUND:

Panasonic's ERJ series became one of the company's major surface-mount resistor families during the electronics industry's long transition from through-hole construction to automated SMD assembly.

Earlier electronic equipment commonly used axial leaded resistors mounted through circuit-board holes. As electronic products became smaller and manufacturing moved toward automated placement and reflow soldering, rectangular chip resistors became standard components in radios, communications systems, automotive electronics, industrial controls, consumer devices, instrumentation, and test equipment.

The 0805 package emerged as one of the most widely used chip-resistor sizes. Measuring approximately 2.0 mm x 1.25 mm, it is compact enough for dense PCB layouts while remaining comparatively manageable for manual service and rework.

High-value resistors such as 18M ohms serve a more specialized role than familiar values such as 100 ohms, 1K, or 10K. They are often chosen when the circuit must establish a DC reference or controlled leakage path while loading the signal or high-voltage node as little as possible.

Historically, megohm-range resistors became especially important in vacuum-tube equipment, measurement instruments, electrostatic circuits, high-voltage equipment, sensitive analog stages, and later semiconductor circuits containing MOSFET and CMOS inputs with extremely high input impedance.

In modern electronics, megohm-range SMD resistors continue to appear in voltage detection, battery monitoring, high-voltage feedback, sensor interfaces, low-power electronics, input protection, discharge paths, and measurement circuits.

ERJ-6GEYK186V also carried Panasonic's AEC-Q200 qualification, reflecting the growing use of standardized passive components in automotive and other environments requiring controlled reliability and temperature performance.

The RF Boneyard inventory shown here is original older distributor stock carrying date code 1813M and an original package quantity of 100 pieces. The current remaining quantity is 85 pieces.

Unlike many current ERJ resistor values that remain in continuous production, ERJ-6GEYK186V has reached end-of-life status. Original unused stock therefore has particular value for exact-part repair, maintenance, legacy-equipment support, and restoration.
