Product Details:
Overview
The Murata BLM21AG121SN1D is a high-performance ferrite bead engineered for effective EMI suppression in modern electronic circuits. Its primary function is to attenuate unwanted high-frequency noise by presenting a significant impedance at specific frequencies, thereby safeguarding sensitive signal paths. A critical design consideration when employing ferrite beads is the trade-off between impedance at the target frequency and DC resistance; while the BLM21AG121SN1D offers a robust 120 Ohms at 100 MHz, its 100mOhm DC resistance ensures minimal voltage drop and power dissipation under load, crucial for power integrity in high-current applications.
Key Features
- Impedance: 120 Ohms @ 100 MHz
- Current Rating (Max): 800mA
- DC Resistance (DCR) (Max): 100mOhm
- Operating Temperature: -55°C to 125°C
- Package / Case: 0805 (2012 Metric)
- Dimensions: 2.00mm x 1.25mm x 1.05mm
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- High-frequency signal line filtering in mobile device RF front-ends.
- Power supply decoupling for sensitive analog circuitry.
- EMI mitigation for high-speed digital interfaces (e.g., USB, HDMI).
- Noise suppression in automotive electronic control units (ECUs).
