Frequently Asked Questions

What is the inductance and current rating of the ELL8TP680MB, and what switching applications does it target?

The ELL8TP680MB provides 68 µH inductance with ±20% tolerance and supports a rated DC current of 1300 mA. These specifications make it well suited for output chokes in DC-DC buck converters operating at switching frequencies between 50 kHz and 500 kHz, as well as energy storage inductors in boost regulators for LED drivers and portable consumer electronics.

How does the 0.14 Ω DCR of ELL8TP680MB affect efficiency in a 5V DC-DC converter design?

With a DC resistance of 0.14 Ω at 1300 mA rated current, the ELL8TP680MB dissipates approximately 0.24 mW of conduction loss at full load, keeping inductor I2R losses minimal in a 5V converter. This low DCR is achievable because of the wire-wound construction on a ferrite core, which maintains high inductance density without sacrificing efficiency compared to higher-resistance alternatives.

Does the shielded construction of ELL8TP680MB reduce radiated EMI in sensitive analog circuits nearby?

Yes, the ELL8TP680MB uses a shielded ferrite-core construction that contains the magnetic flux within the core body, significantly reducing stray magnetic field radiation compared to an unshielded inductor of the same 68 µH value. This is especially important in mixed-signal PCB layouts where a power inductor operating at 100 kHz to 300 kHz would otherwise induce noise into adjacent ADC or audio signal paths.

What SMD case size does ELL8TP680MB use, and how does that compare to a through-hole 68 µH inductor in board space?

The ELL8TP680MB uses a 3131 SMD case (approximately 3.1 mm x 3.1 mm footprint), enabling reflow soldering and occupying a fraction of the PCB area required by an equivalent through-hole 68 µH inductor. In designs targeting miniaturized power modules or multi-layer PCBs with components on both sides, this compact footprint allows placement closer to the switching regulator IC, reducing parasitic inductance in the power loop.
