Gowanda’s 28M123M 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) applications. With an inductance of 120 µH and a minimum Q factor of 95, these coils operate at a test frequency of 0.79 MHz. They have a Direct Current Resistance (DCR) of 4.1 Ω and a Self-Resonant Frequency (SRF) of 10 MHz, with a current rating of 0.195 A DC. The dielectric withstand voltage (DWV) is rated 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 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.
