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

The LCA G1717-902B is a tubular ceramic feedthrough capacitor rated at 300VDC with 2300pF nominal capacitance, manufactured by Fuzhou Lca Electronic Technology Co,ltd in Fujian Province, China. The Y5V ceramic dielectric provides a high dielectric constant in a compact cylindrical form factor, with axial lead terminations for through-hole mounting. Feedthrough capacitors integrate EMI suppression and power supply filtering functions, with the tubular geometry allowing direct passage of the conductor through the ceramic body to achieve low impedance at high frequencies. The 300VDC rating suits industrial power electronics, telecommunications equipment, and instrumentation where line-to-ground or line-to-line filtering is required against conducted electromagnetic interference.

The Y5V dielectric classification indicates a temperature characteristic of +22% to -82% capacitance variation across the operating temperature range of -30 degrees C to +85 degrees C, per EIA standard. This substantial temperature coefficient is acceptable for decoupling and general filtering applications where precise capacitance stability is not critical, but must be evaluated for circuits with tight tolerance requirements. The 2300pF value targets suppression of high-frequency noise in the 100kHz to 100MHz range, with the actual impedance curve dependent on lead inductance and mounting geometry. Standard industry practice for Y5V dielectrics includes verification of insulation resistance, typically specified at 1000 Mohm minimum at 25 degrees C, and dielectric withstanding voltage at 150% of rated voltage for 60 seconds.

Typical applications include switch-mode power supply input filters, DC-DC converter noise suppression, motor drive EMI attenuation, RF equipment power entry filtering, and test instrumentation shielding. The custom size capability noted in the source allows OEM adaptation to specific mechanical constraints, including modified lead spacing, body diameter, and axial length. Buyers should confirm with Fuzhou Lca Electronic Technology the exact dimensions for the G1717-902B part number, lead material and plating (typically tinned copper or copper-clad steel), and whether RoHS compliance documentation is available per the CE and ISO9000 certifications mentioned. The 0.00% response rate requires direct follow-up to validate current production capacity and minimum order quantities for standard and custom configurations.

Fuzhou Lca Electronic Technology Co,ltd is located at 10F, Building A01, Wanyang Entrepreneurial City, No.99 Tingjiang Road, Mawei District, Fuzhou, Fujian 350016, China. The Mawei District is a bonded port area and technology development zone in Fuzhou, providing logistics advantages for electronic component export. The company's trust tier is 'harbor', indicating baseline platform verification. The response rate is 0.00% with zero average response hours recorded, which may reflect a new listing, inactive account, or data collection gap that buyers should verify through direct enquiry before relying on communication responsiveness.

The supplier operates under the LCA brand for passive electronic components, with the G1717-902B representing their tubular ceramic feedthrough capacitor line. The source description indicates custom sizing capability for OEM integration, suggesting some degree of in-house or partnered manufacturing flexibility. No information is provided about factory size, production lines, R and D staff, export experience, or clientele. The ISO9000 certification mentioned is non-current terminology (ISO 9001:2000 was superseded; current is ISO 9001:2015), so buyers should request the current quality management certificate and verify its scope covers ceramic capacitor manufacturing. The supplier's address in a commercial building rather than industrial zone may indicate trading, design, or assembly operations rather than full manufacturing.
