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

Higher DCR leads to more heat loss and decreased efficiency. Smaller physical inductors often have higher DCR because they use thinner wire. Core Material: buy inductor

Smaller inductors save board space but heat up faster. For high-current designs, larger inductors are necessary to prevent heat-related failures. ): The point where the core material can

): 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: Core Material: Smaller inductors save board space but

The environment and board layout significantly influence which package you should buy:

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

Select SMD (Surface Mount) for standard pick-and-place manufacturing, or Through-hole for applications requiring higher mechanical strength.
