Gowanda’s 21M152K is a high-quality, reliable molded unshielded RF coil designed for various applications. With a weight of 1.7 grams and dimensions of 14.224 × 5.588 × 5.588 mm, this component is part of the 21M series and features a through-hole technology (THT) mounting type. It is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 15 µH and a minimum Q factor of 45 at a test frequency of 2.5 MHz. The coil has a direct current resistance (DCR) of 0.52 ohms and a self-resonant frequency (SRF) of 32 MHz, with a current rating of 0.442 A DC. It is designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200, with a tolerance of ±10%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it utilizes a powdered iron core. The component is not shielded and operates within a temperature range of -55°C to +105°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) and is fungal inert, ensuring durability and reliability in various environments.
