About Sayin Electronic & Hardware Co., Ltd. - Electric Components Supplier in China

China‑based Sayin Electronic & Hardware Co., Ltd. lists five distinct electric component products in its catalogue. The items include two miniature oven‑controlled crystal oscillators (OCXO), a standard OCXO described as low aging and high stability, an ultra‑miniature OCXO, and two filter types - a crystal filter and an LC filter. All products fall under the broader HS chapter 85 for electrical machinery and equipment, where similar components are commonly classified under headings such as 8542 (receivers, transmitters) or 8543 (parts thereof).

The catalogue focuses on precision timing devices and frequency‑selective filters used in telecommunications, aerospace, and instrumentation. Each OCXO is marketed for high frequency stability, while the filters are intended for signal purification in RF and IF stages. The supplier’s tier is listed as imported with a harbor trust tier, indicating participation in standard customs clearance processes.

Product Range and Specialties of Sayin Electronic & Hardware Co., Ltd.

The listed OCXO models span miniature to ultra‑miniature form factors, typical for equipment requiring space‑constrained high‑stability clocks. Industry specifications often cite short‑term stability of 1×10⁻¹¹ to 5×10⁻¹² over 1 s, temperature coefficients of ±0.5 ppm/°C, and aging rates below 5×10⁻¹⁰ per day. Crystal filters generally exhibit a center frequency tolerance of ±0.1 % and insertion loss under 2 dB, while LC filters are characterized by quality factors (Q) of 50 - 200 and bandwidths from 10 kHz to several MHz. Buyers normally compare these parameters against standards such as IEC 60705 for frequency stability and IEC 60718 for filter performance.

Trade and Export Information - Sayin Electronic & Hardware Co., Ltd.

China is a major exporter of precision electronic components, with the majority of OCXOs and RF filters shipped from coastal provinces to markets in North America, Europe, and Southeast Asia. Export logistics typically use 20‑ft or 40‑ft containers with anti‑static packaging, and Incoterms such as FOB Shanghai or CIF Hong Kong are common. Buyers often request certifications like ISO 9001 for quality management and CE marking for European compliance, although the supplier’s specific certifications are not listed. HS codes in chapter 85 require conformity assessments for electromagnetic compatibility (EMC) and, where applicable, RoHS compliance for lead‑free soldering.

Sourcing from Sayin Electronic & Hardware Co., Ltd. - Buyer Guidance

When sourcing OCXOs or filters from this supplier, request a datasheet that includes stability curves, aging data, supply voltage range, and mechanical dimensions. For filters, ask for S‑parameter files (S21) and insertion loss graphs across the specified frequency band. Verify that the manufacturer can provide test reports aligned with IEC 60705 (OCXO) or IEC 60718 (filters) and, if required by the destination market, a Declaration of Conformity for RoHS and CE. Sampling is typically done in anti‑static trays with a minimum order of one unit per model to assess performance before larger purchases.

What types of oscillators does Sayin Electronic & Hardware Co., Ltd. offer?

The catalogue lists four oven‑controlled crystal oscillators: a miniature OCXO, an ultra‑miniature OCXO, a low‑aging high‑stability OCXO, and a standard OCXO model.

Are technical datasheets available for the OCXO models?

Buyers should request the manufacturer’s datasheet, which normally contains frequency stability, temperature coefficient, aging rate, supply voltage, and mechanical dimensions.

What specifications define the crystal and LC filters?

Typical specifications include center frequency tolerance (±0.1 %), insertion loss (<2 dB for crystal filters), bandwidth (10 kHz‑several MHz), and quality factor (Q 50‑200 for LC filters.

Which HS codes are applicable to these products?

Precision oscillators and filters are generally classified under HS chapter 85, often under headings 8542 for receivers and transmitters or 8543 for parts thereof.

What certifications are commonly required for importing these components?

International buyers usually request ISO 9001 quality management certification, CE marking for European markets, and RoHS compliance documentation.

What packaging and shipping methods are typical for these electronic components?

Anti‑static bags or trays packed in sealed cartons are standard, with shipment by sea in 20‑ft or 40‑ft containers using FOB or CIF terms.

What is the typical lead time for a sample order?

Suppliers often provide a single‑unit sample within 2‑4 weeks after receiving a formal request and payment of any applicable sample fees.

Are there minimum order quantities for bulk purchases?

While the catalogue does not state a specific MOQ, many Chinese component exporters set MOQs ranging from 100 to 500 units per model, depending on packaging and testing requirements.
