Gowanda’s 8M222M Molded Unshielded RF Coils are high-quality electronic components designed for reliable performance in various applications. These coils weigh 0.25 grams and have compact dimensions of 5.08 × 1.98 × 1.98 mm, making them suitable for space-constrained environments. Part of the 8M 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 integration. With an inductance of 22 µH and a minimum Q factor of 45, these coils operate efficiently at a test frequency of 2.5 MHz. They have a direct current resistance (DCR) of 4.3 ohms and a self-resonant frequency (SRF) of 20 MHz, supporting a current rating of 0.105 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, with a tolerance of ±20%. The coils feature lead-based terminations with a Sn63Pb37 finish and are constructed with a powdered iron core. They are not shielded and can operate in temperatures ranging from -55°C to +105°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.
