This document describes the features and characteristics of MITSUMI Adjustable Type Coils K Series products produced by Dinghao Company, including inductance, operating frequency, variable range of F and L, internal capacitance and unloaded Q value. The specifications and features of each model are also provided.
This handbook provides the technical specifications for Mitsumi's adjustable type coils in the K series, including models such as K5‑S, K5‑N, K7‑P and K7‑T. Each model's inductance range, operational frequency, variable tolerance, internal capacitance and unloaded Q are listed.
Key parameters such as inductance (e.g., 1~300 µH for K5‑S), frequency (0.1~20 MHz for most models), tolerance (F:±2%, L:±4‑5%), and Q factor (40~140) are presented together with packaging details like SMD 1000 pcs/reel or 500 pcs/reel and mounting‑hole recommendations.
| Operational frequency (K5‑S) | 0.1~20 MHz |
|---|---|
| Inductance range (K7‑P) | 1~1600 µH |
The K7‑P series operates from 0.1 to 20 MHz.
