15M221M

Gowanda’s 15M221M Molded Unshielded RF Coils are a part of the Series 15M, designed for high-quality, reliable performance in electronic applications. These coils weigh 0.65 grams and have dimensions of 9.525 × 3.962 × 3.962 mm, making them suitable for through-hole technology (THT) mounting. They are classified under the Commercial Off-The-Shelf (COTS) application grade, with an inductance of 2.2 µH and a minimum Q factor of 33 at a test frequency of 7.9 MHz. The coils feature a direct current resistance (DCR) of 0.95 Ω, a self-resonant frequency (SRF) of 135 MHz, and a current rating of 0.435 A DC. They are designed to withstand a dielectric withstanding voltage (DWV) of 1000 volts and have a tolerance of ±20%. The termination type is lead-based (Pb) with a finish of Sn63Pb37, and the core material is phenolic. These coils are not shielded but are fungal inert and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level (MSL) of 1 and are available in tape and reel (T&R) packaging.
