Description and Introduction

SMD/BLOCK Type EMI Suppression Filters The part **BLM03AG121SN1D** is a chip ferrite bead manufactured by **Murata**. Here are its specifications:

- **Type**: Chip Ferrite Bead (EMI Suppression Filter)
- **Impedance**: 120Ω at 100MHz
- **Rated Current**: 200mA
- **DC Resistance**: 0.4Ω (max)
- **Operating Temperature Range**: -55°C to +125°C
- **Package Size**: 0201 (0603 metric)
- **Material**: Nickel-Zinc (NiZn) ferrite
- **Applications**: Noise suppression in high-frequency circuits, EMI filtering in portable devices, and signal lines.  

This component is designed for surface-mount applications and is commonly used in mobile devices, RF circuits, and other compact electronics.

Application Scenarios & Design Considerations

SMD/BLOCK Type EMI Suppression Filters

Alternative Part Number

  • MPZ0603S121CT000 --: Same 0201 (0603 metric) ferrite bead with 120 ohm impedance at 100 MHz, directly interchangeable in most EMI suppression designs.
  • BLM18PG121SN1D --: Murata ferrite bead with the same 120 ohm impedance rating but in a larger 0603 (1608 metric) case; usable where board space allows and a drop-in electrical equivalent.
  • MMZ0603S121CT000 --: 0201 multilayer ferrite bead with 120 ohm impedance at 100 MHz, suitable as a functional substitute for general-purpose noise suppression.
  • GZ0603D121TF --: 0603 ferrite bead with 120 ohm impedance, close DC resistance and rated current, suitable drop-in substitute from a different manufacturer series.
