21M272M

Gowanda’s 21M272M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 1.7 grams and have dimensions of 14.224 × 5.588 × 5.588 mm, making them compact yet efficient. Part of the 21M series, they are mounted using Through-Hole Technology (THT) and are suitable for Commercial Off-The-Shelf (COTS) applications. With an inductance of 27 µH and a minimum Q factor of 60, these coils operate at a test frequency of 2.5 MHz. They feature a direct current resistance (DCR) of 1.3 Ω and a self-resonant frequency (SRF) of 22 MHz, with a current rating of 0.275 A DC. The dielectric withstand voltage (DWV) is specified at 1000, 200, and they have a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core is made from powdered iron. These coils are not shielded but are designed to operate within a temperature range of -55°C to +105°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, they are also fungal inert, ensuring durability and reliability in various environments.
