About Tgs Crystals Ltd. - Electronic Oscillator Supplier in China

Tgs Crystals Ltd. is based in China and currently lists five active products in its catalogue. The supplier’s portfolio covers quartz crystals, cylindrical crystals, crystal oscillators, crystal filters and ceramic filters. The quartz crystal entry is classified under HS code 8541.60 and is described as a piezoelectric synthetic quartz (SiO2) material. These items fall within the broader electronic oscillator and ceramic filter categories identified in the supplier’s top categories. The catalogue does not provide HS codes for the remaining four products.

The listed products are typical components used in frequency control and signal processing applications. Quartz crystals serve as the resonant element in many timing devices, while cylindrical crystals are shaped for specific mounting configurations. Crystal oscillators combine a quartz resonator with an electronic circuit to deliver a stable output frequency, and crystal filters provide band‑pass characteristics for RF front‑ends. Ceramic filters, also included, are widely employed in intermediate frequency stages of radio receivers. All items are identified by their material composition or function rather than by detailed specifications in the supplier’s data.

Product Range and Specialties of Tgs Crystals Ltd.

From the supplied catalogue Tgs Crystals Ltd. offers five distinct items: quartz crystals (synthetic SiO2 piezoelectric), cylindrical crystals, crystal oscillators, crystal filters and ceramic filters. In the quartz crystal market, common grades include AT‑cut for temperature stability and BT‑cut for high‑frequency applications, with frequency tolerances typically ranging from ±10 ppm to ±50 ppm and load capacitance values between 5 pF and 20 pF. Cylindrical crystals are often produced in dimensions such as 3 mm × 5 mm or 6 mm × 10 mm and meet IEC 60747‑4 specifications for resonant frequency and quality factor (Q). Crystal oscillators are supplied as standard series such as 8 MHz, 12 MHz, 16 MHz and 20 MHz, featuring output stability of ±20 ppm over - 40 °C to 85 °C. Crystal filters are typically specified by center frequency, bandwidth (e.g., 3 dB bandwidth of 10 MHz), and insertion loss not exceeding 2 dB. Ceramic filters commonly appear in values like 455 kHz IF filters for AM radios, with insertion loss below 1.5 dB and temperature coefficients within ±30 ppm/°C.

Industry practice for these components includes anti‑static packaging, moisture‑sealed bags and 20‑foot container shipments of 10 kg cartons. Buyers often request compliance with RoHS and ISO‑9001 quality management, and performance data conforming to IEC 60747 standards.

Trade and Export Information - Tgs Crystals Ltd.

China is a global exporter of quartz and ceramic frequency‑control components, supplying electronics manufacturers across East Asia, Europe and North America. Products classified under HS code 8541.60 are subject to customs inspections that verify compliance with electromagnetic compatibility (EMC) regulations and RoHS restrictions on hazardous substances. Typical importers include telecom equipment makers, automotive electronics suppliers and consumer‑device assemblers who require stable oscillators and filters for RF front‑ends.

Export shipments from China usually employ full‑container‑load (FCL) containers with anti‑static liners, and Incoterms such as FOB Shanghai or CIF Los Angeles are common. Buyers generally request test reports aligned with IEC 60747‑4 for crystals and IEC 60747‑3 for ceramic filters, along with certificates of conformity for RoHS and REACH. While Tgs Crystals Ltd. does not list specific certifications in the provided data, purchasers should verify the presence of ISO 9001 or equivalent quality‑management certification before finalising contracts.

Sourcing from Tgs Crystals Ltd. - Buyer Guidance

When sourcing from Tgs Crystals Ltd., buyers should request detailed datasheets that specify resonant frequency, tolerance, load capacitance, Q‑factor, temperature range and aging characteristics for each crystal type. Sample orders should be accompanied by a test report confirming compliance with IEC 60747 standards and a declaration of RoHS conformity.

Potential buyers should also confirm the supplier’s packaging method - e.g., anti‑static bags within moisture‑controlled cartons - and inquire about minimum order quantities, which commonly start at 1 000 pieces for bulk crystal orders. Lead times for quartz crystal production in China typically range from 2 to 4 weeks, depending on the complexity of the frequency specification and any custom coating requirements.
