The LCA® Miniature Feedthrough Capacitor Series focuses on high performance and miniaturization, specially designed for the RF front-end of wireless communications. This product features a capacitance of 25pF, a capacitance tolerance of -0%+100%, a rated voltage of 60VDC, a withstanding voltage of 150VDC, a rated current of 7A, and a dielectric of X7R. It serves as a core guarantee for high-end wireless devices to achieve efficient signal links.
Miniature RF Filters are compact, high-performance EMI/RFI suppression components specifically developed for electronic systems where limited installation space, reliable electromagnetic compatibility, and stable high-frequency performance are essential. Compared with conventional solder-in feedthrough filters, this product family incorporates a precision gold-plated metal housing with an epoxy sealing structure, providing improved electrical conductivity, enhanced corrosion resistance, and long-term operational reliability in demanding electronic environments.
Model HA3630-019 features a 25 pF capacitance, 60 VDC rated voltage, and C-type circuit configuration. It provides an excellent balance between compact dimensions, filtering effectiveness, and long-term operational stability.
Selected models are additionally available with gold wire bondable terminals, allowing direct integration into hybrid circuits, microwave assemblies, and advanced electronic packaging. Customized bonding structures can also be developed to satisfy specific application requirements.
✔ Compact miniature design for space-constrained electronic assemblies
✔ Gold-plated metal housing for excellent electrical conductivity
✔ Epoxy sealing construction for reliable mechanical protection
✔ Outstanding EMI/RFI suppression across a wide frequency range
✔ Stable high-frequency electrical performance
✔ High corrosion resistance for long-term reliability
✔ Solder-in mounting for secure electrical grounding
✔ Gold wire bondable terminals
The gold-plated housing is one of the key design features that distinguishes LCA Miniature RF Filters from conventional solder-in feedthrough filters. Gold provides outstanding electrical conductivity while maintaining a stable, oxidation-resistant surface over extended service periods. This helps reduce contact resistance, improve grounding efficiency, and maintain consistent filtering performance throughout the product’s operating life.
Compared with standard surface finishes, gold plating also offers superior corrosion resistance in demanding environments, making these filters particularly suitable for precision RF systems, medical devices, and long-life industrial equipment where electrical reliability cannot be compromised.
