When sourcing an inductor, these "sticky note" parameters are essential to match your design requirements: Inductance Value (
The "workhorse" for power supplies and EV chargers due to high flux and low loss at several MHz.
Best for very high-frequency RF applications because they have no core losses. Physical and Application Factors buy inductor
): 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:
Consider shielded inductors if your circuit is sensitive to electromagnetic interference (EMI) or if the inductor must sit near other high-frequency components. Where to Buy Inductor Market Size, Share, Trends & Growth Report, 2030 When sourcing an inductor, these "sticky note" parameters
The continuous current the part can handle without overheating. Saturation Current ( Isatcap I sub s a t end-sub
A cheaper alternative often used for lower frequency applications but prone to higher losses at high frequencies. It determines how much magnetic energy is stored
The environment and board layout significantly influence which package you should buy:
