NFZ5BBW520LZ10L Filters

Ferrite Beads and Chips

Ferrite beads and chips are one of the most commonly used electronic components for filter and impedance matching applications. NFZ5BBW520LZ10L is a particular type of ferrite bead in a low pass filter. It is very useful for noise suppression, signal filtering, and emission control.

Application Field

NFZ5BBW520LZ10L ferrite bead has many applications and is mainly used for impedances matching, signal filtering and basic noise suppression applications. It is widely used in consumer electronics, telecommunications, computer systems, automotive electronics, and much more. It can reduce the RF emissions from electronic appliances to comply with emission standards, such as CISPR 11, FCC Part 15B, or VCCI requirements. It is also used in medical equipment, such as ultrasound, to reduce electromagnetic interference in the vicinity of the equipment.

Working Principle

Noise suppression ferrite beads are basically absorptive low pass filters that use ferrite cores to dissipate high frequency energy into heat. The NFZ5BBW520LZ10L has a compact size and is made from a special material with a high Curie temperature. It can dissipate more power than conventional ferrite beads and maintain its performance at higher frequencies. The internal construction consists of a number of loops and windings. Diodes are placed across the windings in order to create a one-way circuit and direct the current in the desired direction. As current passes through the beads, it induces a voltage in the windings that create a self-inductance effect. This counteracts the current and creates an impedance which dissipates high frequency energy. The energy is effectively blocked from reaching the rest of the circuit or device.

The NFZ5BBW520LZ10L has a high impedance in the high frequency range and a low impedance in the low frequency range. The frequency response is very steep and maximizes the noise suppression effect, allowing it to effectively block and dissipate high frequency noise. This makes the NFZ5BBW520LZ10L the ideal choice for application fields requiring high performance noise suppression.
