28M332M

Gowanda’s 28M332M 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, making them suitable for through-hole technology (THT) mounting. Part of the 28M series, they are classified as Commercial Off-The-Shelf (COTS) grade, offering an inductance of 33 µH with a minimum Q factor of 60 at a test frequency of 2.5 MHz. The coils feature a direct current resistance (DCR) of 0.55 ohms, a self-resonant frequency (SRF) of 19 MHz, and a current rating of 0.525 A DC. They are designed to withstand dielectric withstanding voltages (DWV) of 1000 and 200 volts, with a tolerance of ±20%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and the core is made of powdered iron. These coils are not shielded and can operate in temperatures ranging from -55°C to +125°C. They have a moisture sensitivity level (MSL) of 1, are packaged in tape and reel (T&R), and are fungal inert.
