Gowanda’s 21M182JLF is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil weighs 1.7 grams and measures 14.224 × 5.588 × 5.588 mm, making it compact yet efficient. It belongs to the 21M series and is mounted using through-hole technology (THT). The component is suitable for commercial off-the-shelf (COTS) applications, offering an inductance of 18 µH with a minimum Q factor of 50 at a test frequency of 2.5 MHz. It features a direct current resistance (DCR) of 0.7 Ω and a self-resonant frequency (SRF) of 28 MHz, with a current rating of 0.38 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it has a tolerance of ±5%. The termination type is RoHS compliant with a Sn/Cu finish, and it uses a powdered iron core. Although it is not shielded, it operates effectively within a temperature range of -55°C to +105°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the component is also fungal inert, ensuring durability and reliability in various environments.
