Import Hc-49s Quartz Crystal Resonator — Buy in Bulk from Supplier in China

The HC-49S Quartz Crystal Resonator offered by Zhuhai Tong Ching Quartz Technology Co., Ltd. is designed for communication devices such as wireless phones and other digital equipment. It features a metal package with lead‑free pins, frequency coverage from 3.2 MHz up to 90 MHz, and operates in both fundamental and third‑harmonic vibration modes. The resonator provides a static capacitance of up to 7 pF, an equivalent series resistance of 1 Ω, and a driving power rating of 100 µW (500 µW maximum).

The device uses parallel‑welded metal shells for reliable automatic installation, and its load capacitance can be selected from 16 pF, 18 pF or 20 pF according to circuit needs. Typical quartz resonators of this series exhibit a tolerance of ±30 ppm at 25 °C, a temperature stability range of - 20 °C to +70 °C, and a storage range of - 40 °C to +85 °C, which aligns with industry standards for mobile‑device components. An aging rate of ±5 ppm per year is common for this class, ensuring predictable long‑term frequency drift.

Buyers such as OEMs of mobile handsets, IoT module manufacturers and contract electronics assemblers commonly source this resonator for its compact size and reliable frequency performance. Trade terms, including Incoterms, payment schedules and packaging specifications, should be confirmed directly with the supplier before placing an order. The supplier’s response metrics indicate a current response rate of 0 % and no recorded average response time, so proactive communication is advised.

Zhuhai Tong Ching Quartz Technology Co., Ltd. is located in the Nan Ping Technology Park of Zhuhai, Guangdong Province, China (No. 3 Lu Yuan Road). The company is classified as an imported tier supplier and carries a harbor trust tier, indicating it meets basic verification requirements within the marketplace ecosystem.
