Polypropylene Film Capacitors 560NF/400V (L564J)

Product Description

The Polypropylene Film Capacitor 560NF/400V, marked with the code 564J, is a metallized polypropylene film capacitor built for applications that demand stability, low loss, and reliable performance at moderate voltage levels. With a capacitance of 560nF (0.56µF) and a voltage rating of 400V, it belongs to the widely used CBB21/CL21 family of film capacitors commonly found in power electronics, filtering circuits, and general analog design work.

Unlike electrolytic capacitors, which are polarized and tend to degrade over time due to their liquid or gel dielectric, this capacitor uses a metallized polypropylene film as its dielectric material, giving it a non-polar design that can be installed in either orientation without risk of reverse-voltage damage. This construction also gives polypropylene film capacitors a reputation for low dielectric absorption, low equivalent series resistance, and good long-term capacitance stability, qualities that matter in circuits where precise, consistent filtering or timing behavior is required over the capacitor's lifetime.

The 564J marking follows the standard three-digit capacitor coding system, where the first two digits represent the significant figures and the third indicates the multiplier, working out to 560,000pF, or 560nF. The "J" suffix denotes a tolerance of ±5%, meaning the actual capacitance will fall within a tight band of the rated 560nF value, an important consideration for circuits sensitive to component variance, such as oscillators, timing networks, or precision filters.

With a 400V rating, this capacitor is well suited for use in circuits operating at higher voltages than typical low-voltage ceramic or electrolytic capacitors can safely handle, making it a practical choice for AC line filtering, snubber circuits, motor start/run applications, and power supply designs where voltage spikes or ripple need to be managed without risking component breakdown. Its through-hole, two-pin design with a 15mm lead pitch makes it straightforward to mount on standard perfboard, breadboard-adjacent prototyping setups, or custom PCB layouts using a matching footprint.

Because film capacitors like this one handle AC signals and voltage transients more gracefully than many other capacitor types, they're a common choice in power supply units, audio crossover networks, EMI suppression circuits, and general-purpose analog filtering where signal integrity and long-term reliability matter more than achieving the highest possible capacitance in a small footprint.

For hobbyists, engineers, and repair technicians working on power electronics, audio equipment, or general circuit design, this 560nF/400V polypropylene film capacitor offers a dependable, non-polarized component suited to moderate-voltage filtering and coupling applications where stability and low loss are priorities.
