- Iron-alloy core provides graceful saturation behavior, preventing abrupt inductance collapse under transient overcurrent conditions
- General-purpose power inductor compatible with standard reflow soldering in DC-DC buck/boost converter output stages
Applications
The 74438323022 is suitable for DC-DC buck converter output filter inductors and boost converter energy-storage elements where a 2.2 µH, 0.176 Ω SMD chip inductor is required in a space-constrained 1008 footprint. Its 1 mm low profile supports flat designs in wearable electronics, mobile device power management ICs, and IoT sensor nodes. The iron-alloy core tolerates current spikes in load-transient-heavy applications such as microcontroller reset sequences and wireless radio burst transmissions.

Frequently Asked Questions
What inductance and DCR does the Würth 74438323022 offer in the 1008 SMD package?
The 74438323022 provides 2.2 µH nominal inductance with a DC resistance of 0.176 Ω, housed in a 1008 SMD case with a 1 mm maximum height. This combination makes it appropriate for moderate-current DC-DC converters in IoT devices and portable electronics where both board area and component height are tightly constrained.
How does the iron-alloy core of the 74438323022 behave under load transients in a buck converter?
Iron-alloy cores exhibit a gradual, soft saturation characteristic rather than the abrupt inductance collapse seen in some ferrite materials. When load transients push instantaneous current beyond the rated value, the 74438323022 maintains partial inductance, limiting peak switch current and protecting MOSFET switches in 5 V to 12 V buck converters. This soft saturation is particularly valuable in microcontroller power rails where 100 mA to 500 mA load steps are common during active and sleep mode transitions.
Which portable or wearable device power stages can use the 74438323022's 1 mm profile to save vertical space?
Smartwatch and fitness tracker power management modules, hearing aid power converters, and thin-profile IoT sensor nodes all benefit from the 1 mm height of the 74438323022. At 2.2 µH and 0.176 Ω DCR, it covers the inductor requirements for 500 kHz to 2 MHz switching converters delivering 100 mA to 400 mA, matching the power budgets of BLE SoCs, MEMS sensors, and low-power microcontrollers in sub-4 mm total-height PCB assemblies.
