Capacitance and PCA-HPMS Components

What is Capacitance?

All materials hold some form of capacitance—the ability to hold a charge and therefore slowly lose the charge. 

When it comes to electrical circuits, capacitance occurs when an electrical conductor—like a cable—interacts with an electrical charge. The cable generates a closed circuit and the electrical charge creates a load in the cable. This means that capacitance is created between the conductors carrying current. 

Capacitance is critical for electrical systems. It influences signal integrity, power efficiency, and overall performance. 

Why Does Capacitance Matter?

The real-world implications of capacitance are far-reaching. High capacitance can mean lost energy, delayed signals and interference (especially in high frequency uses).

However, if you’re careful, capacitance can actually help performance. It can lead to smooth signal transmission and power efficiency.

What is Stray Capacitance

How is Capacitance Handled in PCA High-Performance Components?

The PCA-HPMS team knows how important it is to make sure capacitance is working with you rather than against you. Our engineers work hard to design components that balance capacitance to create optimal performance. 

Capacitance is crucial for the precise functioning of devices like endoscopes and ultrasounds and PCA-HPMS can address these needs with our high-quality components delivering accuracy and reliability. 

PCA-HPMS excels at creating custom solutions for our customers for their specific application. Whether adjusting capacitance for a specific signal or enhancing insulation to relax its effects, our R&D capabilities help us stay innovative and effective. 

Capacitance Ranges with PCA-HPMS Components

HPMS has an unparalleled range of standard wire and cable sizes, and our attention to detail and precision is evident throughout specialized cables, which includes impedance and capacitance-controlled options.  

Some Capacitance controlled components: 

  • Low-Capacitance Micro-Coaxial Cable. PCA’s advanced foam PFA extrusion process delivers low-capacitance cable. Polyester tape skin over the foam is utilized to ensure the dielectric layer can reliably withstand reasonable voltage the medical industry requires. Wire sizes from 38-48 AWG with capacitance 50 – 60 pf/m with impedance range of 70 – 85 ohms are available. 
  • High-Capacitance Micro-Coaxial Cable. Copper alloy wire in precision wire gauges ranging from 36-50 AWG are available. These superfine, high-strength, highly conductive, 7-strand constructions are useful for small-diameter flexible cables. We also offer standard 50 and 60-ohm impedance products.
