The BLM15KD200SN1D is a high-performance SMD ferrite bead manufactured by Murata Manufacturing Co., Ltd. Belonging to the BLM15KD series, this chip ferrite bead features an impedance of 20Ω at 100MHz, an impedance tolerance of ±25%, and a rated current of 3.8A, providing an effective solution for high-frequency noise suppression and electromagnetic interference (EMI) filtering in electronic circuits.
Designed in an ultra-compact 0402 (1005 Metric) package, the BLM15KD200SN1D supports high-density PCB layouts and automated surface-mount assembly. With a maximum DC resistance of only 11mΩ, it helps minimize voltage drops and power losses while suppressing unwanted high-frequency noise.
The device operates over a temperature range of -55°C to +125°C. Its rated current is 3.8A at an ambient temperature of 85°C and 2.35A at 125°C, making it suitable for electronic designs requiring compact size, high current capability, and effective EMI suppression.
The BLM series ferrite bead technology provides resistive characteristics at noise frequencies, helping reduce unwanted resonance and improve noise suppression performance.
