Panasonic ERJ-2RKF4992X 49.9k 1% 0402 SMD Thick Film Resistors – 90 Pieces
$9.95
Original labeled distributor NOS packet containing 90 Panasonic ERJ-2RKF4992X precision thick-film surface-mount resistors. Each resistor has a resistance value of 49.9 k? with ±1% tolerance, 0.1-watt (1/10-watt) power rating, ±100 ppm/°C temperature coefficient, and a -55°C to +155°C operating-temperature range. The compact 0402 package measures approximately 1.00 x 0.50 mm with a maximum seated height of 0.40 mm. These resistors are suitable for voltage dividers, feedback networks, bias circuits, sensing circuits, control boards, audio equipment, RF support circuits, communications equipment, test equipment, and general surface-mount board repair. The ERJ-2RK series is AEC-Q200 compliant and designed for reliable automated surface-mount assembly. Supplied in original labeled distributor packaging.
Historical Note: Panasonic’s ERJ precision thick-film resistor family uses a metal-glaze resistive element with layered electrode construction. This construction represents the electronics industry’s long-running transition toward compact and dependable chip resistors for high-density automated circuit-board production.
