The Panasonic FR series capacitors are radial leaded, polarized aluminum electrolytic capacitors designed for high-performance applications. They have a capacitance of 1500µF and operate at a voltage of 6.3V. These capacitors are ideal for circuits requiring ultra-low equivalent series resistance (ESR), high ripple current capability, and long lifespan in a compact form factor. Compared to the Panasonic FM series, the FR series offers up to 100% improved endurance and up to 30% higher capacitance due to advanced material technology.
