Durable & Versatile: jb JFG Axial Film Capacitors for High Voltage Use
When designing for high-voltage conditions, reliability and flexibility are everything. That’s why many engineers today turn to axial film capacitors — and among them, jb’s JFG Series has quietly gained attention for its practical balance of durability, size efficiency, and performance consistency.
These capacitors are available in cycloidal and flat oval structures, supporting voltage ratings up to 1250VDC. Their self-healing film construction — in either polyester (PET) or polypropylene (PP) — ensures long-term stability even under pulse load or elevated temperature.
What Makes the JFG Series a Solid Choice?
While there’s no “one-size-fits-all” in capacitor selection, the JFG series offers a versatile option across a wide range of designs. It’s used in everything from audio crossover systems to switching power supplies — a reminder that robustness doesn’t have to come at the cost of footprint.
Its axial lead form factor also makes it a favorite for engineers who value clean signal paths and mechanical stability in long traces.
Curious About the Differences Between PET and PP?
We cover that in more detail on our Film Materials Comparison page.
If your project involves frequent switching, PP might offer the thermal advantage you’re looking for.
PET, meanwhile, is a cost-efficient performer for many standard circuits.
