About Shenzhen TGD Crystal Electron Co., Ltd - Ceramic Filters Supplier in China

Shenzhen, China hosts Shenzhen TGD Crystal Electron Co., Ltd, which currently lists 16 active products on its B2B catalogue. The catalogue is concentrated on ceramic and quartz resonators, crystal filters and related oscillator modules. Products include crystal resonators, quartz resonators, SMD tuning‑fork resonators at 32.768 kHz, ceramic resonators, SAW resonators and SAW filters, as well as SMD crystals and oscillator assemblies. All items fall under electronic component categories used for timing and frequency control in consumer and industrial electronics. The supplier is classified as an imported tier with a harbor trust level.

The primary category identified in the supplier’s data is Ceramic Filters, but the product list also spans quartz crystal resonators, ceramic resonators, tuning‑fork devices and oscillator modules. Each entry is recorded without additional technical attributes, leaving the buyer to verify frequency, load capacitance and temperature specifications from the supplier’s data sheets. The range covers both surface‑mount (SMD) and through‑hole formats, reflecting typical form‑factor options for PCB integration.

Product Range and Specialties of Shenzhen TGD Crystal Electron Co., Ltd

The catalogue covers crystal resonators, quartz resonators, SMD tuning‑fork resonators (commonly 32.768 kHz for watch and microcontroller clocks), ceramic resonators, SAW resonators, SAW filters, and complete oscillator modules. In the industry, crystal resonators are usually specified by frequency tolerance (±30 ppm to ±100 ppm), load capacitance (typically 12.5 pF or 20 pF), and operating temperature range (‑40 °C to +85 °C). Ceramic resonators are often offered in standard frequencies such as 4.915 MHz, 8 MHz, 12 MHz, with tolerance of ±0.5 % and lower cost for non‑critical applications. SAW resonators and filters typically provide bandwidths from 10 MHz to 200 MHz with insertion loss under 2 dB and are used in RF front‑ends. Oscillator modules integrate a resonator with amplification circuitry and are supplied as complete timing solutions for microprocessors and communication devices.

Trade and Export Information - Shenzhen TGD Crystal Electron Co., Ltd

Electronic timing components such as resonators and filters are a major export segment from China, with the majority of shipments classified under HS Chapter 85 (electrical machinery and equipment). Resonators are usually recorded under sub‑heading 8542.31, while ceramic and SAW filters fall under 8543.39. Main importing regions include Southeast Asia, Europe and North America, where manufacturers of consumer electronics, automotive infotainment and industrial control gear source these parts. Buyers typically require compliance with RoHS, REACH and, where applicable, CE marking for market entry. Shipping is commonly performed in 20 ft or 40 ft containers, with anti‑static packaging and moisture‑absorbing bags to protect the crystal lattice during transit.

Sourcing from Shenzhen TGD Crystal Electron Co., Ltd - Buyer Guidance

When sourcing from Shenzhen TGD Crystal Electron Co., Ltd, request the latest product data sheet that specifies frequency, tolerance, load capacitance, temperature range and aging characteristics. Ask for a RoHS conformity test report and, if required by the destination market, an IEC 60730 or IEC 61558 compliance certificate. Verify the packaging method - anti‑static bubble wrap, moisture‑absorbing desiccant and sealed cartons are standard for crystal devices. Typical minimum order quantities for resonator families range from 5,000 to 10,000 pieces, with lead times of 4‑6 weeks after order confirmation. Confirm the supplier’s willingness to provide sample units for performance testing before committing to full‑scale production.

What types of resonators does Shenzhen TGD Crystal Electron Co., Ltd list in its catalogue?

The supplier lists crystal resonators, quartz resonators, SMD tuning‑fork resonators (including the 32.768 kHz version), ceramic resonators, SAW resonators and SAW filters, as well as complete oscillator modules.

Are ceramic filters included in the product range?

Yes, the catalogue includes ceramic filters and a specific series identified as LTC455DWSeries, which are typical for RF filtering applications.

Which frequency standards are common for the tuning‑fork resonators offered?

Tuning‑fork resonators are most often supplied at 32.768 kHz, a standard frequency for watch crystals and low‑power microcontroller clocks, with load capacitance typically around 12.5 pF.

What documentation should a buyer request before placing an order?

Buyers should request a full technical data sheet, RoHS compliance test report, and, if required for the target market, CE or REACH conformity documentation.

What are typical packaging requirements for crystal and ceramic components?

Standard practice is anti‑static bubble wrap, moisture‑absorbing desiccant packets and sealed, double‑wall cartons to prevent humidity damage during transport.

What are common minimum order quantities and lead times for these components?

Minimum order quantities usually start at 5,000 units per part, with an estimated lead time of 4‑6 weeks after order confirmation, depending on production scheduling.

Which HS code categories are generally applied to these products when exported from China?

Resonators and crystal parts are typically classified under HS 8542.31, while ceramic and SAW filters fall under HS 8543.39, both within Chapter 85 for electrical equipment.

How are the products usually shipped to overseas buyers?

Shipments are commonly consolidated in 20 ft or 40 ft containers, using palletized cartons that meet anti‑static and moisture‑control standards, with Incoterms such as FOB Shenzhen or CIF destination port.
