Features
1.Frequency specified filters are designed to reduce noise greatly at specified frequency. which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. BLF series is effective in circuits without stable ground lines because BLF series does not need a connection to ground. 2.The nickel barrier structure of the external electrodes provides excellent solder heat resistance. 3.BLF03JD series is designed to have high impedance at 700MHz to 1GHz. Suitable for immunity noise suppression for GSM band. 1 of 3
