รายละเอียดสินค้า

BLM21PG221SN1D is a high-performance, miniaturized ferrite bead widely used in various electronic devices, and plays an important role in improving the stability and signal-to-noise ratio of the circuit.
Package and size
1. Package form: 0805 (2.0mm×1.25mm), which is a miniaturized package that is very suitable for high-density circuit board applications.
2. Height: 0.85mm, the low design makes it easy to layout in space-constrained electronic products.

คุณสมบัติ
Electrical performance
1. Rated current: 2000mA at 85℃ and 1250mA at 125℃, the high rated current makes it suitable for high-current circuits.
2. Maximum DC resistance: 45mΩ (also expressed as 0.045Ω), low DC resistance helps reduce energy loss.
3. Impedance: 220Ω at 100MHz, the impedance value is high, which has a significant effect on filtering high-frequency noise and suppressing interference signals.
4. Operating temperature range: -55℃ to 125℃, the wide operating temperature range makes it suitable for various working environments with large temperature changes.

Other features
The external electrode adopts a nickel grid structure, which provides excellent welding heat resistance.
No grounding is required, suitable for circuits without stable grounding.
BLM21PG series beads can be used in high current circuits because of their low DC resistance value, which can match the power line to a maximum of 6A DC.
