bkp1608hs601-t: FAQs
Q1: What does 600 Ω @ 100 MHz mean?
It represents the impedance of the ferrite bead when tested at 100 MHz. A higher impedance indicates stronger filtering for high-frequency noise.
Q2: Can I use it for power lines?
Yes, but only for lines drawing under 0.35 A. For heavier currents, select a ferrite bead with a higher current rating.
Q3: How does it compare to capacitors?
Capacitors filter low-frequency noise, while ferrite beads are effective against high-frequency EMI. They complement each other in a filter design.
Q4: What happens if the current exceeds its rating?
Exceeding 0.35 A can cause the bead to heat up, lose efficiency, and possibly degrade over time.
Q5: Is it still available?
Some sources mark it as discontinued, but replacement options exist with similar specifications and performance.
