Ferrite Beads and Chips

Ferrite beads and chips are common components used in many electronic devices. They are small components that filter or shield electrical currents from interference. The MPZ1005S300CT000 is a chip-like, surface-mount, ferrite bead for use in power supplies and general circuits. It works by providing a high impedance barrier to high frequency noise coming from other circuits. It also provides attenuation for common-mode signals.

What is the MPZ1005S300CT000?

The MPZ1005S300CT000 is a ferrite bead chip manufactured by Murata. It is a low cost surface mount chip designed for power supplies, EMI control and signal conditioning in general circuit applications. The chip has a resonance frequency of about 500MHz and an impedance of in the range of 100-300 ohms. It also has a low insertion loss of up to 0.2dB. The bead is sized to fit in relatively small spaces due to its small size measurements of 3.45x 2.00mm.

Application Field

The MPZ1005S300CT000 ferrite bead is commonly used in automotive, power supply, and communication applications. Automotive use includes airbag systems, EFI systems, ABS brake systems, LCD displays, and power and signal circuits. In the power supply market, the chip is used in low noise power supplies and EMI filter circuits. In the communication sector, it is used in cable-based networks, mobile base stations, and cellular phones.

Working Principle

The MPZ1005S300CT000 ferrite bead works by providing a high impedance barrier to high frequency electrical signals. The outside surface of the chip is typically covered in a metal coating, such as platinum, which maintains the impedance of the chip. The bead is also designed to provide attenuation of common mode signals, which can reduce cross-talk and interference between devices.The chip is also designed to be capable of operating at a wide temperature range and a wide frequency range. It is also designed to have a low insertion loss, meaning that it will not affect the signal passing through it. The chip has a small size and is designed to fit into tight spaces, making it perfect for use in many applications.

Conclusion

The MPZ1005S300CT000 ferrite bead chip is a low cost, small size chip designed for applications in automotive, power supply, and communication markets. It has a resonance frequency of 500MHz and an impedance range between 100-300 ohms, making it perfect for EMI filtering and signal conditioning. The chip has a small size and is designed to fit in small spaces, making it perfect for use in many application.
