Inductor: Buy

): Measured in Henrys (H), usually ranging from nanohenries (nH) to millihenrys (mH). It determines how much magnetic energy is stored and is typically chosen based on your "ripple budget". You must account for two distinct values:

The "workhorse" for power supplies and EV chargers due to high flux and low loss at several MHz. buy inductor

Smaller inductors save board space but heat up faster. For high-current designs, larger inductors are necessary to prevent heat-related failures. ): Measured in Henrys (H), usually ranging from

Select SMD (Surface Mount) for standard pick-and-place manufacturing, or Through-hole for applications requiring higher mechanical strength. Smaller inductors save board space but heat up faster

When sourcing an inductor, these "sticky note" parameters are essential to match your design requirements: Inductance Value (

): The point where the core material can no longer support additional magnetic flux, causing a sharp drop in inductance.

A cheaper alternative often used for lower frequency applications but prone to higher losses at high frequencies.
