RK73 PRECISION 1% & 0.5% TOLERANCE FLAT CHIP RESISTORS
The RK73 series from Speer Electronics offers precision flat‑chip resistors with 1 % (F) and 0.5 % (H) tolerance options. Available in eight standard sizes (0201, 0402, 0603, 0805, 1206, 1210, 2010, 2512) and resistance values from 0.1 Ω to 22 MΩ, the parts are suitable for a wide range of electronic applications.
The resistors are supplied in punched‑paper, embossed‑plastic, and tape‑and‑reel formats, with nickel‑barrier terminations and 90/10 solder‑plated finishes. They meet EIA‑575, EIAJ‑RC‑2690A, EIA‑PDP‑100, and MIL‑R‑55342F standards and are rated for operating temperatures from –55 °C to +125 °C and voltages of 200 V (0402) or 400 V (larger sizes).
