KTA5050 Series

Ultra-Low Loss Shielded Power Inductors

The KTA5050 Series molded power inductors offer ultra-low inductance values starting from 65 nH, making them ideal for today’s low-voltage, high-current DC-DC converters. Designed for single-phase and multiphase VRMs and PoL regulators, the KTA5050 delivers fast transient response, high current handling, and low DC as well as AC losses in a compact package. The series is ideal for modern CPUs, GPUs, ASICs, and SoCs in servers, data centers, as well as automotive power applications.

Small and compact package size – only 5.6 x 5.2 x 5.2 mm
Low inductance for fast transient response and high power in multi-phase solution
Soft saturation with high current rating
Exceptionally low power losses
AEC-Q200 qualified

Notes

When ordering, please specify packaging code: e.g. KTA5050-601MEC
Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4395A or equivalent.
Isat: DC current at 25°C that causes an inductance drop of 30% (typ) from its value without current.
Temperature derating curves.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, air flow, and proximity to other components. Therefore temperature rise should be verified in application conditions. Temperature derating curves.

**Voltage capability varies by part number and in many cases may be higher than the listed voltage.
