Gowanda’s 17S270K is a high-quality, reliable molded shielded RF coil designed for various applications, particularly in the COTS grade. This component weighs 0.7 grams and measures 10.414 × 4.115 × 4.115 mm, making it suitable for through-hole technology (THT) mounting. It features an inductance of 0.27 µH with a minimum Q factor of 47, tested at a frequency of 25 MHz. The coil has a direct current resistance (DCR) of 0.11 Ω and a self-resonant frequency (SRF) of 250 MHz, supporting a current rating of 0.855 A DC. It is designed to withstand a dielectric withstanding voltage (DWV) of 1000 volts and operates within a temperature range of -55°C to +105°C. The component has a tolerance of ±10% and uses a Pb termination type with a Sn63Pb37 finish. The core material is phenolic, and it is shielded to enhance performance. It is packaged in tape and reel (T&R) format and is rated with a moisture sensitivity level (MSL) of 1, although it is not fungal inert.
