MS91189 inductor leaded Series

The MS91189 inductor from API Delevan Inc. is a phenolic-based, unshielded RF inductor designed for high-frequency applications. If you're working on projects involving RF circuits, these inductors can be quite useful. They operate well in the range of 1 MHz to several GHz, making them suitable for various RF amplifiers, filters, and oscillators.

One thing worth noting is their stability over temperature and frequency. Phenolic materials provide a good balance between thermal stability and electrical performance, which is crucial in RF designs where temperature variations can significantly impact circuit behavior. Engineers tend to reach for this type of inductor when they need reliable performance across a broad frequency spectrum without the added complexity of shielding.

These inductors show up frequently in systems like wireless communication devices, radar systems, and medical equipment that require precise RF tuning and filtering. Their unshielded design keeps the footprint compact, which is beneficial in space-constrained applications. However, if your application requires shielding against electromagnetic interference, you might want to consider shielded alternatives.
