90 PCS Panasonic ERJ-3EKF1021V 1.02K ohm 1% 0.1W 0603 SMD Thick Film Resistors

Original distributor package containing 90 PCS Panasonic ERJ-3EKF1021V precision thick-film surface-mount resistors.

These resistors provide a 1.02K ohm / 1020 ohm resistance value with 1% tolerance and a 0.1W / 1/10W power rating in the compact 0603 SMD package. The ERJ-3EKF1021V is part of Panasonic's ERJ-3EK precision thick-film chip resistor family and provides a ±100 ppm/°C temperature coefficient.

The original distributor labeling identifies Panasonic, 0603 package, 1.02K ohm value, country of origin China, and date code 1519.

This package contains 90 PCS and is sold as one complete package.

Lifecycle: ACTIVE.

HISTORICAL BACKGROUND:
Panasonic's ERJ family became widely used as electronics manufacturing transitioned from through-hole resistor assemblies to compact automated surface-mount production. The ERJ-3EK series uses the common 0603 footprint, providing a practical balance between small board area, dependable electrical characteristics, automated assembly capability, and serviceability during repair.

The 1.02K ohm value is an E96 precision resistance value commonly used where a standard 1K resistor does not provide the required circuit ratio or calibration point. Precision values such as 1.02K are found in voltage dividers, bias circuits, feedback networks, sensing circuits, signal-conditioning stages, gain-setting networks, timing circuits, instrumentation, control electronics, and calibrated analog designs.

The 1% tolerance and ±100 ppm/°C temperature coefficient provide tighter resistance control than ordinary 5% general-purpose resistors, making the part useful in circuits where accuracy and repeatability are important.

Original distributor-packaged Panasonic stock is useful for repair benches, engineering inventory, prototype work, small production runs, legacy board repair, and maintaining equipment designed around ERJ-series components.
