Frequently Asked Questions
What is the inductance value and tolerance of the B78108S1475J000, and how does it affect filter performance?
The B78108S1475J000 has a nominal inductance of 4700 µH with ±5% tolerance. This high inductance value provides strong attenuation of high-frequency signals and noise, making it effective as an RF choke or low-pass filter in circuits operating below 0.7 MHz self-resonant frequency, where inductance remains stable.
What is the maximum DC current rating and DC resistance of the B78108S1475J000 inductor?
The B78108S1475J000 is rated for a maximum DC current of 55 mA with a DC resistance of 78 Ω. These parameters define the power dissipation limit; exceeding 55 mA risks saturation of the ferrite core and inductance roll-off, so this part targets low-power RF and signal filtering stages rather than power conversion.
For which RF or EMI suppression circuit designs is the B78108S1475J000 most appropriate?
This 4700 µH ferrite leaded inductor is best suited for EMI suppression filters, RF choke circuits, and signal line decoupling in consumer and industrial electronics operating below 0.7 MHz. Its tubular through-hole package with 0.8 mm leads is compatible with standard PCB drilling patterns and wave soldering processes used in volume production.
