Panasonic ERJ-3EKF1000V 100 ohm 1% 0.1W 0603 Automotive SMD Resistor 30 PCS
Full Description & History
Panasonic ERJ-3EKF1000V automotive-grade thick-film surface-mount resistor rated 100 ohms, ±1% tolerance, and 0.1 W in the 0603 / 1608 metric package.
This device is AEC-Q200 qualified and designed for reliable operation in automotive, industrial, communications, control, and general electronic circuits. Panasonic specifies a ±100 ppm/°C temperature coefficient, approximately 75 V working-voltage rating, and an operating temperature range from -55°C to +155°C.
The 100-ohm value is widely useful in signal limiting, series termination, bias networks, LED current limiting, protection networks, digital interfaces, and general board-level repair.
Original Mouser packaging identifies Panasonic ERJ-3EKF1000V, 0603 size, 100 ohms, 1% tolerance, thick-film construction, and automotive AEC qualification. The package shows country of origin China and date code 2130.
Lifecycle: ACTIVE.
HISTORICAL BACKGROUND: Panasonic traces its origins to 1918, when Konosuke Matsushita founded the company that grew into one of Japan’s largest electronics manufacturers. Beyond consumer electronics, Panasonic developed extensive component operations producing resistors, capacitors, relays, switches, batteries, sensors, semiconductors, and industrial electronic devices.
The ERJ family became one of Panasonic’s major chip-resistor product lines as electronic manufacturing moved from through-hole components toward automated surface-mount assembly. Thick-film construction provided manufacturers with a dependable and economical method of producing large quantities of precision resistors in standardized miniature packages.
The 0603 package became one of the most common surface-mount resistor sizes because it offers a useful balance between small PCB footprint, automated assembly, power capability, and serviceability.
The ERJ-3EK series adds automotive AEC-Q200 qualification to the standard thick-film chip-resistor format. AEC-Q200 qualification subjects passive components to environmental and reliability testing intended for harsh automotive conditions including temperature cycling, humidity, vibration, and extended service life.
This exact ERJ-3EKF1000V remains an active Panasonic Industry production part, making these original distributor-stock devices useful both for current electronics work and long-term repair inventory.
