CR0402-FX-2202GLF is the 22 kΩ member of Bourns’ CR series of general-purpose thick film chip resistors, in the 0402 size — a 1.00 × 0.50 mm body just 0.32 mm thick, built on a three-layer termination with a nickel barrier under the tin plating.^{p.2, p.1} Tolerance is ±1 %, and like every CR0402 the top carries no marking — the value travels in the ordering code (2202 → 22 kΩ, 3 significant digits + 2 zeros), not on the part.^{p.1, p.5, p.6}

Design against 1/16 W at 70 °C ambient — the rating derates linearly above that and reaches zero at +155 °C^{p.1, p.3} — and keep continuous voltage at or below 50 V; the 100 V figure is an overload limit, not a working one.^p.1 TCR is ±100 ppm/°C across the 10 Ω–1 MΩ ±1 % band this value sits in.^p.1 A 2.5× rated-voltage, 5-second overload is allowed to shift the value by up to ±(2 % + 0.1 Ω) — worth knowing if a transient can land across it.^p.4
