FEATURES ? Wide Frequency Characteristics R-series chip beads are able to generate impedances over a wide range of frequencies, which mainly consists of a resistance. ? Higher Low-frequency Impedances R-series chip beads are able to generate higher impedances at low frequencies. ? Prevents Signal Ringing R-series chip beads contain resistive elements that effectively prevent signal ringing of CMOS IC. ? Multiple Size Availability R-series chip beads are available in three compact sizes: 160808, 201209, and 321609.
