Select SMD (Surface Mount) for standard pick-and-place manufacturing, or Through-hole for applications requiring higher mechanical strength.
When sourcing an inductor, these "sticky note" parameters are essential to match your design requirements: Inductance Value ( 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: You must account for two distinct values: Smaller
Smaller inductors save board space but heat up faster. For high-current designs, larger inductors are necessary to prevent heat-related failures. Saturation Current ( Isatcap I sub s a
The continuous current the part can handle without overheating. Saturation Current ( Isatcap I sub s a t end-sub
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
