Gowanda’s 21M152M 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. They belong to the 21M series and are mounted using Through-Hole Technology (THT), suitable for Commercial Off-The-Shelf (COTS) applications. With an inductance of 15 µH and a minimum Q factor of 45, these coils operate at a test frequency of 2.5 MHz. They feature a Direct Current Resistance (DCR) of 0.52 Ω and a Self-Resonant Frequency (SRF) of 32 MHz, with a current rating of 0.442 A DC. The coils are designed to withstand Dielectric Withstanding Voltages (DWV) of 1000 and 200, with a tolerance of ±20%. They have a lead-based termination type with a Sn63Pb37 finish and are constructed with a powdered iron core. Operating efficiently in temperatures ranging from -55°C to +105°C, these coils are rated at Moisture Sensitivity Level (MSL) 1 and are packaged in Tape and Reel (T&R) format. Additionally, they are fungal inert, ensuring durability and reliability in various environments.
