Import Dielectric Resonator — Buy in wholesale FOB from Supplier in China

The Dielectric Resonator offered by Strong First is a ceramic microwave component used for frequency stabilization in RF modules. The supplier’s data sheet lists the SDRE852B610D06/150-H954 model with a centre frequency of 852 ± 3 MHz, a minimum Q-value of 17000 and a temperature coefficient of frequency of 2.0 ± 1 ppm/°C, housed in a 61.0 x 30.0 mm package. Another example, the SDRM2620B080D06-H954, operates at 2620 ± 20 MHz, provides a Q-value of 3800, a temperature coefficient of 1.0 ± 1 ppm/°C and fits in an 8.0 x 8.5 mm case. All figures are taken directly from the supplier’s specifications.

All models are fabricated from high-purity alumina ceramic, a material recognised for its low loss tangent and stable dielectric constant. In the industry the relative dielectric constant for such resonators typically ranges between 10 and 12, and the centre-frequency tolerance is commonly +/-0.5% of the nominal value. Standard operating temperature limits are usually -40°C to +85°C, matching the temperature coefficient values reported by Strong First. These typical parameters indicate that the resonators meet the performance expectations for telecom and satellite equipment.

The resonators are employed in low-noise block converters, base-station repeaters, LNB assemblies and Doppler-shift measurement devices, where high Q and temperature stability are critical. Importers targeting telecom infrastructure or aerospace projects often request custom dimensions or dielectric constant adjustments, which Strong First notes as design-flexible. The listing does not disclose minimum order quantities, lead-time or payment terms, so buyers should confirm those details directly with the supplier. Shipping is typically arranged under FOB Shenzhen or CIF Shanghai, depending on the buyer’s preference.

Strong First is located in Shenzhen, Guangdong province, China, at Room 1910, Paradise Building, Banxuegang Road, Longgang District. The supplier is classified in the harbour tier of the marketplace verification system, but its response rate is currently recorded as 0% with no average response time, indicating that communication may require proactive follow-up. Strong First specialises in custom dielectric resonator design, offering a range of frequencies and Q-values to match specific RF applications. The company’s catalogue lists a variety of standard and stepped-mode parts.

The listing provides detailed technical data for each model but does not disclose pricing, minimum order quantities, lead-time estimates or certification status. Strong First states that the resonators can be customised for different dielectric constants or package sizes, yet any such modification would need to be negotiated directly with the supplier. The supplier’s profile does not mention any third-party quality certifications such as ISO 9001, so buyers should request documentation if required for their procurement standards.
