IQD 4MHz Crystal HC49/4H Series, 11mm x 4.7mm, 20ppm, 30pF
Reliable 4MHz through-hole crystal from IQD, ±20ppm tolerance, 30pF load, ideal for clock timing.
The IQD 4MHz Crystal (LFXTAL003074) is a high-quality through-hole crystal oscillator component designed for precise clock timing. It features a resistance-welded, hermetically sealed construction with inert atmosphere and glass-to-metal seals on leads, ensuring long-term reliability and durability.
Built for robustness, it is tested for shock resistance (3 times in each of 3 mutually perpendicular planes) and vibration (30 minutes in 3 mutually perpendicular planes). With a fundamental vibration mode, this crystal offers low equivalent series resistance (130Ω maximum) and low drive level (500µW maximum), making it suitable for a range of timing applications.
