Import Crystal Units — Buy in Bulk from Supplier in China

The HC-49U crystal unit supplied by Yantai Cn Electronics Co., Ltd. is a quartz crystal oscillator component used to stabilise frequency in electronic circuits. It features a compact housing that fits standard PCB footprints and provides high‑frequency stability across a wide frequency range as indicated by the supplier. The unit is manufactured to meet ISO and SGS quality standards, and each piece is individually tested before dispatch. This model is commonly sourced by manufacturers of telecommunications gear, consumer electronics, automotive control modules and industrial equipment.

In the broader market, quartz crystal oscillators of the HC‑49U form factor typically use a quartz resonator with a frequency tolerance of +/-30 ppm and a load capacitance of 18 pF (typical values). Standard operating temperature limits are - 20 °C to +70 °C and the dimensions are usually 7.5 mm × 5.0 mm (typical). These typical parameters ensure reliable performance in temperature‑sensitive applications.

Buyers usually request flexible minimum order quantities and confirm the presence of ISO or SGS certificates before purchase. Shipping is offered on FOB or CIF terms, and the units are packed in anti‑static protective bags to prevent damage during transit. Importers should verify the supplier’s response reliability and arrange payment through secure trade channels.
