ELECTRO CAP - 386-1059-000 - F500B305K- 3uF 100V Polypropylene Radial Capacitor

Polypropylene capacitors are designed for general purpose filtering applications. Their stability and low
loss characteristics make them an excelllent choice for blocking, filtering, bypassing, coupling and decoupling applications.

A crossover serves as a filter that blocks out unwanted frequencies to a speaker or group of speakers. This is extremely useful because it allows us to specifically send each speaker the group of frequencies that it will play most efficiently and effectively.
