Busbar for Busbar Film Capacitor
Products Description
The Busbar for Busbar Film Capacitor is a precision engineered busbar system specifically developed for interfacing film capacitor modules in high-performance power-electronic systems. It provides a reliable and efficient interconnection between film capacitors and DC or high-frequency bus networks in application scenarios such as inverters, converter racks, energy storage systems, and traction drives. The assembly includes a conductor layout (copper or plated-copper), multiple insulation layers, termination end-fixtures (bolts, welds, press-fits), and the option for tailor-made dimensions and shapes to match specific film-capacitor modules. By incorporating this Automotive Power Connectors into your design, you gain a dedicated interconnect solution optimized for low inductance, low impedance, high reliability and ease of integration into your power-electronic architecture.
Product Feature
Conductor Low-Impedance Design
The Busbar Automotive employs high conductivity copper (or tin/silver-plated variants) with large cross-section geometry, optimized path length and tight layout to minimize resistance and power loss in high-current and high-switching environments.
01
Ultra Low Parasite Inductance
The busbar system is engineered for minimal stray inductance (ESL) and minimal parasitic impedance, thereby enhancing dynamic performance, reducing overshoot and oscillation risk in pulse and high-frequency operations.
02
Multi-layer Composite Insulation
Designed for high-voltage DC or pulsed applications, the Tin-plate Busbar Automotive integrates multi-layer insulation films (for example Mylar, Kapton, Tedlar) plus edge-sealing and encapsulation to ensure dielectric integrity and minimise partial-discharge risk.
03
Tailored Interface for Film Capacitors
The termination design is matched to film capacitor modules: bolted or welded lugs, press-fit connections, mounting alignment and module-specific layouts-ensuring rapid connection, reliable contact and simplified assembly.

Manufacturing Advantage
| Precision Fabrication | The Tin Plated Copper BusBar for EV is manufactured using advanced stamping, bending, welding or bolting, plating (tin, silver) and finishing processes. These ensure conductor uniformity, flat contact surfaces and consistent assembly quality. |
| Stringent Quality Control | From raw material intake through insulation lamination, plating inspection, assembly, finishing and final electrical/thermal testing-each production batch is subject to rigorous inspection (e.g., dielectric withstand, partial discharge, thermal cycle, contact resistance) to ensure repeatable performance and reliability. |
| Materials and Inventory Readiness | High-quality copper stock, advanced insulation films, plated terminal hardware and modular assembly lines allow fast turnaround from prototype to volume production, reducing lead-times for engineering customers. |
| Modular Assembly Capability | We support pre-assembled Automotive Power Connectors modules integrated with film capacitor banks, offering "plug-and-play" capability for system integrators and reducing on-site integration effort. |
| Flexible Production Scale | Whether an initial pilot run of a few units or a full commercial launch of thousands per annum, the manufacturing line scales accordingly, supporting both custom projects and high-volume supply. |
