L滤波 inductors are primarily used in conjunction with capacitors and resistors to form filters, typically made of ferrite materials. In some high-performance filters, wound inductors are employed. Filters composed of inductors, capacitors, and resistors can effectively filter out specific frequency points or frequencies outside of those points from the power line, resulting in a power signal of a specific frequency or eliminating the power signal after a specific frequency.
The primary characteristics of inductive filters are their ability to pass direct current while blocking alternating current, and to pass low frequencies while blocking high frequencies. Depending on the frequency band of the signal passing through, they can also be referred to as low-pass filters or band-stop filters.
Based on data collection and market analysis from multiple institutions, the射频 frontend market where filters are located holds promising prospects, accounting for nearly half of the revenue share. As a type of filter, the inductor's market share is also believed to be substantial, which fully illustrates that the passive component industry's future remains optimistic. The key lies in whether we can seize the opportunities.
