The K Type Series adjustable coils from Mitsumi are offered in a variety of part numbers (K5‑S, K5‑S2, K5‑N, K7‑P, K7‑D, etc.). Each coil is supplied as an SMD component on a 1000 pcs/reel tape and is designed for use in high‑frequency filter and resonant applications.
For each model the handbook lists key electrical parameters such as inductance range, operating frequency, tolerance (F), internal capacitance, and unloaded Q factor. The data enables designers to select the appropriate coil based on the required inductance, frequency band, and quality factor.
| Inductance range | 1~300 µH (K5‑S) / 1~1600 µH (K7‑P) |
|---|---|
| Operating frequency range | 0.1~20 MHz (K5‑S, K7‑P) |
The K5‑S coil provides an inductance from 1 µH up to 300 µH.
The K7‑P coil operates over a frequency range of 0.1 MHz to 20 MHz.
