Coupled Inductors 330µH 1.22A 0.482Ω - Model DRQ125-331-R
Manufactured by EATON ELECTRONICS, this high-performance coupled inductor is designed for advanced electronic applications. With a COO of CN and a UOM of each (EA), it complies with RoHS standards and features an ECCN of EAR99. The product is supplied in a reel package for efficient automated assembly.
Product Features:
Dual winding, shielded drum core power inductor suitable for use as a single inductor or in coupled inductor/transformer applications with a 1:1 turns ratio.
Offers four sizes of shielded drum core inductors with windings connectable in series or parallel, providing a broad range of inductance and current ratings.
Peak current ratings up to 56A and RMS current ratings up to 17.9A, supporting high-power applications.
Inductance ratings from 0.33µH to 4.02mH, with a typical inductance of 330µH for this model.
200 Vac isolation between windings ensures safety and reliability in high-voltage environments.
Constructed with ferrite core material for optimal magnetic performance.
Designed for use in DC-DC converters, VRM in CPU and DDR power supplies, input/output filter chokes, and various transformer applications such as SEPIC and flyback.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
