Import Crystal Filter — Buy in Bulk from Supplier in China

Shenzhen TGD Crystal Electron Co., Ltd supplies crystal filters that operate across a frequency range of 10.000 to 100 MHz. The catalogue lists two compact form factors - 6.9 × 8.0 × 3.4 mm and 6.9 × 6.0 × 3.4 mm - matching the UM‑1 and UM‑5 size designations. Both dimensions are suited to surface‑mount assembly in modern electronic devices, and the supplier notes that custom frequency solutions can be engineered on request.

The filters are fabricated from quartz crystal, the material most commonly used for frequency‑selective components because of its low temperature coefficient and high stability. In the wider market, typical insertion loss for comparable quartz filters is below 0.5 dB and quality factors (Q) exceed 2000, which helps preserve signal integrity in high‑frequency circuits. Standard industry tolerances for length and width are ±0.05 mm, while thickness variation is usually within ±0.02 mm, ensuring reliable placement on printed circuit boards.

Typical buyers include telecom equipment manufacturers, radio‑broadcasting transmitters and consumer‑electronics firms that need precise channel selection. Shenzhen TGD offers flexible minimum order quantities, and the listing mentions shipping options such as FOB and CIF together with payment methods including L/C and T/T. Prospective importers should confirm the exact lead time and any custom packaging requirements before placing an order.
