Frequently Asked Questions
What inductance value and tolerance does the DFE201612P-R33M=P2 provide for DC-DC converter designs?
The DFE201612P-R33M=P2 provides 0.33 µH nominal inductance with ±20% tolerance. This low inductance value is ideal for high-frequency DC-DC switching regulators typically operating from 1 MHz to 10 MHz, where smaller inductance reduces physical size while maintaining sufficient energy storage for efficient power conversion in portable devices.
How does the metal alloy core construction affect performance at high switching frequencies?
The metal alloy core of the DFE201612P-R33M=P2 provides lower core losses compared to ferrite at high switching frequencies, typically above 1 MHz. This results in higher efficiency DC-DC converters with reduced heat generation, and the core exhibits a gradual saturation curve that improves current handling in power management applications where peak currents may momentarily exceed rated values.
What footprint dimensions does the 0806 package occupy on a PCB, and how does this compare to larger inductors?
The 0806 (2016) package measures 2.0 mm × 1.6 mm, occupying only 3.2 mm² of PCB area. This is significantly smaller than common 1210 inductors at 12.5 mm², making the DFE201612P-R33M=P2 an excellent choice for space-constrained wearables, smartphones, and IoT modules where board real estate is at a premium.
When would a designer choose the DFE201612P-R33M=P2 over an inductor with higher DCR in a battery-powered product?
In battery-powered designs, minimizing DC resistance is critical to extending battery life. The DFE201612P-R33M=P2's 0.028 Ω DCR produces very low I²R conduction losses; for example, at 1 A load current the resistive power loss is only 28 mW. Competing inductors with DCR above 0.1 Ω would dissipate over 100 mW at the same current, directly reducing battery run time by increasing thermal load in the power stage.
