How SMD Y Capacitors Help EMS Providers Reduce Costs

For EMS and PCBA manufacturers, reducing production costs is no longer just about sourcing lower-cost components. The real challenge is finding solutions that improve manufacturing efficiency, simplify assembly, and maintain product reliability.

One area that is often overlooked is the choice of Y safety capacitors.

In a recent evaluation for a customer project, JYH HSU (Dongguan Zhixu Electronics, JEC) compared traditional through-hole Y capacitors with our newly developed copper-electrode SMD Y capacitors.

The results highlighted several advantages that are highly relevant to EMS providers and electronics manufacturers:

Fully compatible with automated SMT assembly

Unlike through-hole capacitors that require additional insertion and wave soldering processes, SMD Y capacitors can be placed directly during SMT production, reducing labor requirements and improving manufacturing efficiency.

Lower overall production costs

By eliminating manual insertion, lead trimming, and secondary processing steps, manufacturers can reduce assembly costs and streamline production workflows.

Better suitability for compact PCB designs

As electronic products become smaller and more integrated, board space becomes increasingly valuable. The low-profile SMD package helps designers optimize PCB layouts while supporting high-density assemblies.

Excellent leakage current performance

Testing showed significantly lower leakage current compared with traditional through-hole designs, helping engineers maintain safety margins and support compliance with international safety standards.

Potential for quieter operation

The SMD structure is directly mounted to the PCB, which can help reduce mechanical vibration and board resonance, making it an attractive solution for applications where acoustic noise is a concern.

For EMS companies serving industries such as power supplies, smart appliances, industrial electronics, and consumer electronics, selecting the right passive components can improve both manufacturing efficiency and product competitiveness.

At JYH HSU (Dongguan Zhixu Electronics), we develop capacitor solutions designed to help customers reduce assembly costs, improve reliability, and support large-scale automated production.
