Import 300vdc Tubular Seramic Feedthrough Capacitors — Buy in wholesale FOB from Supplier in China

Tubular ceramic feedthrough capacitors rated at 300VDC with 2300pF capacitance from Fuzhou Lca Electronic Technology serve as EMI suppression components in high-frequency circuits. The part number G1717-902B identifies this specific build within the LCA brand catalogue. These capacitors employ a Y5V dielectric material, a barium titanate ceramic formulation that delivers high permittivity in a compact tubular package. The feedthrough geometry routes the conductor through the capacitor body, providing low-impedance grounding of unwanted noise to the chassis while passing the signal with minimal attenuation.

Y5V ceramic dielectric exhibits a temperature coefficient of +22%, -82% over its operating range, typical for general-purpose decoupling where tight capacitance stability is not demanded. The metal electrode termination ensures solderability and low equivalent series resistance. Feedthrough construction differs from standard disc or multilayer chip capacitors by integrating the lead directly through the ceramic cylinder, which maximises the capacitive coupling to ground. Standard industry tests for this class include capacitance drift under temperature cycling, voltage conditioning, and insulation resistance after humidity exposure. The RoHS and CE markings indicate compliance with European hazardous substance restrictions and electromagnetic compatibility directives.

Buyers in industrial automation, medical equipment, telecommunications infrastructure, and RF instrumentation source these capacitors for filtering switch-mode power supplies, motor drives, and sensitive analogue front ends. The 300VDC rating suits medium-voltage DC buses and rectified AC lines. OEMs and contract manufacturers in power electronics typically request capacitance tolerance, dissipation factor at 1kHz, and DC withstand voltage test data. Packaging and minimum order quantities are not stated in the source materials; confirm reel or bulk packaging options and stock availability directly with the supplier.

Fuzhou Lca Electronic Technology Co, Ltd operates from premises at 10f, Building A01, Wanyang Entrepreneurial City, No.99 Tingjiang Road, Mawei District, Fujian, China, postal code 350016. The Mawei District of Fuzhou is an established industrial zone in China's southeastern coastal province, with access to the port of Fuzhou for export logistics. The supplier holds harbour-tier trust status, which represents a baseline verification level on the platform. Neither response rate data nor average response time is available for this supplier, so direct communication to assess technical support capability is advisable before placing orders.

The company markets capacitors under the LCA brand name, with the G1717-902B part number indicating an internal catalogue system. ISO9000 certification is claimed, though the specific scope and accreditation body are not detailed in the source materials. No production capacity figures, employee count, year of establishment, or major client references are provided. Buyers should request a current quality management system certificate, supplier capability audit report, and sample evaluation batch to validate consistency with the stated Y5V dielectric and 300VDC voltage rating.
