28M221M

Gowanda’s 28M221M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 2.65 grams and have dimensions of 22.86 × 7.137 × 7.137 mm. Part of the 28M series, they feature a through-hole technology (THT) mounting type and are suitable for commercial off-the-shelf (COTS) application grades. With an inductance of 2.2 µH and a minimum Q factor of 60, these coils operate at a test frequency of 7.9 MHz. They have a direct current resistance (DCR) of 0.16 Ω and a self-resonant frequency (SRF) of 125 MHz, with a current rating of 1.6 A DC. The dielectric withstanding voltage (DWV) is 1000, 200, and they offer a tolerance of ±20%. The termination type is lead-based with a Sn63Pb37 finish, and the core material is phenolic. These coils are not shielded and can operate in temperatures ranging from -55°C to +105°C. They have a moisture sensitivity level (MSL) of 1, are packaged in tape and reel (T&R), and are fungal inert.
