Applications
The IHLP4040DZER220M11 is designed for output filter inductors in synchronous buck converters, boost converters, and SEPIC topologies operating at switching frequencies from 100kHz to several hundred kHz. Its 22µH inductance and low 0.066Ω DCR enable high-efficiency power conversion with minimized I²R losses in server power modules, industrial motor drives, and portable computing power stages. The shielded composite structure limits EMI emissions, making it well-suited for power management circuits placed near sensitive analog or RF sections of a PCB.

Frequently Asked Questions
What switching frequency range is the IHLP4040DZER220M11 optimized for in DC-DC converter designs?
The IHLP4040DZER220M11 with 22µH inductance and composite core is well-suited for DC-DC converter switching frequencies ranging from approximately 100kHz to 500kHz. At 100kHz in a buck converter with 5V input and 3.3V output, the 22µH inductor produces typical peak-to-peak ripple current of around 1A to 3A depending on duty cycle, making it appropriate for medium-power point-of-load converters in server and industrial power supply designs.
How does the 0.066Ω DCR of the IHLP4040DZER220M11 impact efficiency in high-current applications?
The IHLP4040DZER220M11 has an exceptionally low DC resistance of 0.066Ω, which means at 5A continuous output current the resistive loss is only 1.65W — far lower than inductors with DCR above 0.1Ω. This low DCR translates directly into higher conversion efficiency in 5A to 10A output DC-DC regulators used in computing, telecommunications, and industrial motor control power stages.
Does the shielded package of the IHLP4040DZER220M11 matter for mixed-signal PCB layouts?
Yes, the IHLP4040DZER220M11 uses a shielded composite core construction in a 4040 package measuring approximately 10.4mm × 10.4mm, which significantly reduces magnetic flux leakage compared to unshielded inductors. In mixed-signal PCBs where a switching power rail operates within 5mm to 10mm of ADC or RF circuitry, the shielded design helps keep inductor-generated EMI below the sensitivity thresholds of 12-bit to 16-bit analog circuits.
