Gowanda’s 28M472M 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 compact installations. Part of the 28M series, they feature a Through-Hole Technology (THT) mounting type and are classified as Commercial Off-The-Shelf (COTS) grade, ensuring versatility and ease of use. With an inductance of 47 µH and a minimum Q factor of 65, these coils operate efficiently at a test frequency of 2.5 MHz. They have a direct current resistance (DCR) of 1 Ω and a self-resonant frequency (SRF) of 16 MHz, supporting a current rating of 0.39 A DC. The dielectric withstand voltage (DWV) is rated at 1000, 200, with a tolerance of ±20%. The coils feature a lead-based termination type with a Sn63Pb37 finish and are constructed with a powdered iron core. They are not shielded but are designed to operate within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, these coils are also fungal inert, ensuring durability and reliability in various environments.
