◆ FEATURES ◆ APPLICATIONS
● Effective EMI Protection
P-Series chip beads have a monolithic
inorganic material construction that
minimizes the effect of electromagnetic
interference.
● Low DC Resistance
P-series chip beads have extremely low DC
resistance. Low DC resistance
characteristics are ideal for noise filtering of
power line.
● High Current Handling
P-series chip beads are designed for high
current handling. P-series chip beads are
able to withstand currents to a maximum of
6A DC.
● Multiple Size Availability
P-series chip beads are available in five
compact sizes: 160808, 201209, 321611,
322513, and 453215.
P-series chip beads can be used in a
variety of electronics including:
• CD-ROMs
• Hard Drives
• Modems
• Monitors
• Motherboards
• Printers
