The SRP4020T Series features an advanced carbonyl iron powder core and shielded construction, providing high saturation current, exceptional heating current, and low magnetic field radiation—key attributes that help minimize electromagnetic interference (EMI) in space-constrained applications.

With an impressive maximum operating temperature of +150°C, excellent current handling capabilities, and a low-profile footprint of just 4.4 x 4.0 x 1.8 mm, these inductors are ideally suited for power supply applications and compact consumer electronics. They also serve as an effective replacement for the now-obsolete SRP0420 Series, ensuring continued high-quality performance.

Features:

  • Series Size: 4.45 x 4.06 x 1.8 mm
  • Inductance Range: 0.47 – 10 µH
  • Heating Current (Irms): 2.6 – 11 A
  • Saturation Current (Isat): 3 – 16 A
  • Operating Temperature Range: -40°C to +150°C
  • Shielded construction for low radiation
  • Carbonyl iron powder core for high performance
  • High saturation current with low buzz noise
  • RoHS compliant* and halogen-free**

Applications:

  • Power supplies
  • Consumer electronics
