Drawn to true relative scale — the variants above are directly size-comparable.
Crystal oscillators & OCXO modules
Gold-coloured lid + white ceramic body = worth pulling. Plain silver steel can with just a frequency stamped on it = leave it.
How to spot it
Two very different things. Bare resonators (HC-49 oblong nickel-plated steel cans, or tiny SMD metal-lidded rectangles) stamped with a frequency — near worthless. Oscillator modules (XO/VCXO/TCXO/OCXO) in DIP-14-footprint or SMD packages, often white ceramic with a gold lid and a longer part number — these are the ones. OCXOs from telecom and test gear are best.
Metal content
| Metal | Quantity | Notes |
|---|---|---|
| Gold | 0.1–0.5 g/lb (modules) | gold lid + pads + internal IC |
| Silver | 0.5–3 g/lb | electrode film, 1–10 mg per crystal |
At 4 Aug 2026 spot prices that works out to $42.0 per pound of contained metal — Gold 0.3 g = $39.2, Silver 1.5 g = $2.85. A refiner paying $10 returns about 24% of that, which is normal: refining costs money and the buyer takes a margin.
Safe removal
Working temperature: Hot air 350 °C
Hot air 350 °C, or preheat and pull. Through-hole DIP oscillators: preheat the board and pull with pliers.
Hazards
NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.
