The Murata BLM18EG series are EMIFIL chip ferrite beads for suppressing high frequency noise in GHz band general signal line applications. These chip ferrite beads are designed for reducing the possibility of resonance to provide undistorted signal waveform. EMIFIL chip ferrite beads do not require connection to ground so they are effectively used in circuits without stable ground lines. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. BLM18EG series has modified internal electrode structure that minimizes stray capacitance and increases the effective frequency range.
* Up to 10 Amps (IMAX) Continuous Operating Capability
The MPZ1608S221ATA00 is a SMD Chip Bead with 0603 case. Noise reduction solution for power line. Compared to the MMZ series, it has low direct current resistance for compatibility with large currents, optimal for low power consumption. Various frequency characteristics for countermeasures against everything from general signals to high-speed signals. Performs well even in signal lines where low direct current resistance is required. Standard type that features impedance characteristics similar to those of a typical ferrite core. For signal line applications in which the blocking region is near 100MHz. Impedance values selected for effectiveness at 40 to 300MHz.
