DRQ125-220-R Details

Coiltronics recommends a PCB layout with a solid ground plane underneath the inductor, and a land pattern with a minimum of 1.5 mm clearance around the component to minimize parasitic capacitance and ensure proper heat dissipation.
The DRQ125-220-R is rated for operation up to 125°C, but derating may be necessary for temperatures above 85°C. Coiltronics recommends consulting their application notes for temperature derating guidelines.
The maximum allowable DC current for the DRQ125-220-R is 22 A, but this value may be affected by the operating temperature and other environmental factors. Coiltronics recommends consulting their application notes for DC current derating guidelines.
Yes, the DRQ125-220-R is suitable for high-frequency switching applications up to 1 MHz. However, Coiltronics recommends consulting their application notes for guidelines on core loss and EMI considerations.
The SRF of the DRQ125-220-R is approximately 10 MHz, but this value may vary depending on the specific application and PCB layout. Coiltronics recommends consulting their application notes for SRF considerations.
