Import Dielectric Filters — Buy in Bulk from Supplier in China

Shijiazhuang Boya Electronic Sci.& Tec. Co., Ltd. supplies dielectric filters that operate across 0.3 to 4.5 GHz, covering a broad spectrum of RF applications. The offered models provide selectable bandwidths from 0.2 % up to 15 % to match precise filter profiles. Insertion loss is engineered to be low, typically ≤ 0.5 dB across the pass‑band. All units conform to ISO standards, ensuring consistent quality and reliability.

The filters employ ceramic dielectric resonators, a common material in high‑frequency signal conditioning. Ceramic construction delivers stable dielectric constant and temperature coefficient, which industry standards cite as essential for aerospace and telecom equipment. Typical dimensions are 20 mm × 10 mm with a coaxial housing, allowing straightforward integration into standard chassis. Operating temperature ranges from - 40 °C to +85 °C, matching the environmental ratings of most electronic enclosures.

These filters are used in telecommunications base stations, broadcasting transmitters and military communication links where signal purity is critical. Purchasers such as system integrators and defence contractors often request bulk shipments with FOB or CIF terms. The supplier states flexible minimum order quantities, though exact figures should be confirmed directly. Payment and shipping details are negotiated per order, making it suitable for both small‑scale trials and large‑volume production.

Shijiazhuang Boya Electronic Sci.& Tec. Co., Ltd. is an imported‑tier supplier located at A‑4th Floor, No.286 Hezuo Road, Shijiazhuang, Hebei, China (postal code 050051). The business holds a harbor trust tier on the platform, indicating a moderate level of verification. Response metrics show a 0 % response rate with no recorded reply time, so communication speed should be verified directly. The company lists electronic components, focusing on high‑frequency devices such as dielectric filters.

According to the listing, the firm does not disclose production capacity or client references, limiting the public profile to the product catalogue. Potential buyers are encouraged to request samples and test reports to assess conformity with the stated ISO compliance. No additional certifications, such as MIL‑SPEC or RoHS, are mentioned in the supplied data. All trade terms, including MOQ and lead time, are to be negotiated with the supplier.
