21M681M

Gowanda’s 21M681M Molded Unshielded RF Coils are a testament to the company’s commitment to high-quality, reliable electronic components. These coils, weighing 1.7 grams, feature dimensions of 14.224 × 5.588 × 5.588 mm and belong to the Series 21M. Designed for through-hole technology (THT) mounting, they are suitable for commercial off-the-shelf (COTS) applications. With an inductance of 6.8 µH and a minimum Q factor of 35, these coils operate at a test frequency of 7.9 MHz. They have a direct current resistance (DCR) of 0.2 Ω and a self-resonant frequency (SRF) of 50 MHz, supporting a current rating of 0.71 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, with a tolerance of ±20%. The coils feature a powdered iron core and are not shielded, with a termination type of Pb and a termination finish of Sn63Pb37. They operate efficiently within a temperature range of -55°C to +105°C, have a moisture sensitivity level (MSL) of 1, and are packaged in tape and reel (T&R) format. Additionally, they are fungal inert, ensuring durability and reliability in various environments.
