In modern power electronic design, effective EMI suppression is a critical challenge. With higher switching frequencies and complex topologies, demand for reliable AC filter capacitors continues to grow. Selecting the right capacitor directly impacts system reliability, thermal performance, and compliance with EMI standards.

The jb® JFQF AC Filter Capacitor series is built with metallized polypropylene film, optimized for AC output filtering in solar inverters, UPS systems, and LCL filters. These capacitors deliver low ESR, high ripple current endurance, and proven long-term stability.

Key Advantages of JFQF Capacitors

• Low ESR and ESL for precise EMI suppression
• High ripple current handling in demanding environments
• Self-healing metallized film ensures long capacitor life
• UL 94V-0 epoxy sealing enhances safety and durability
• Wide voltage ratings — ideal for 250VAC to 480VAC filtering

JFQF capacitors are the preferred choice for engineers seeking stable AC filtering, compact form factor, and EMI reduction in industrial and renewable energy systems.

After updated the ISO certificate, jb capacitors company updated the RoHS compliant also, all jb
products are RoHS Compliant and meet RoHS 2015/863. 

Please check with our sales for the latest SGS report. 

Wish you all have a nice dragon boat festival in advance

Polypropylene Film capacitor CBB65, also know as AC Motor Running Capacitor, which specially designed for air conditioning.
jb JFS 22~26 series CBB65 Motor Running Capacitor is equipped inside with reliable explosion-proof equipment and it is highly safe. 
With its good self-healing characteristic and long life-span, it is widely used for air-conditioners, refrigerators, generators, illuminating lamps, etc. 

The standard voltage for our JFS 22~26 series CBB65 Motor Running Capacitor is 450VAC and 370VAC.
The most common capacitance are 30uF, 35uF, 40uF, 45uF, 50uF, 55uF, 60uF, 65uF 
Usually, under the condition of all the raw material ready, our production line is capable of producing 20000pcs of these capacitors per day.
From May to October is our peak production season for CBB65 Motor Running Capacitors, we suggest you to send your order plan in advance to get a fast lead time.
