Gowanda’s ER17S273KR is a high-quality, reliable molded shielded inductor from the M39010 Level-R series, designed for demanding applications requiring QPL grade components. This inductor features a compact design with dimensions of 9.91 × 3.86 × 3.86 mm and a weight of 1.13 g, making it suitable for through-hole technology (THT) mounting. It offers an inductance of 270 µH, a direct current resistance (DCR) of 5.8 Ω, and a current rating of 115 A DC. The inductor operates efficiently across a frequency range with a self-resonant frequency (SRF) of 7 MHz and a test frequency of 0.79 MHz, maintaining a minimum Q factor of 55. It is built with a ferrite core and shielded for enhanced performance, with a dielectric withstanding voltage (DWV) of 1000, 200. The product is rated for operation in temperatures ranging from -55°C to +105°C, ensuring reliability in various environments. It features a Pb termination type with a Sn63Pb37 finish, and it is packaged in tape and reel (T&R) format for ease of handling. The inductor is classified as MSL 1, indicating its robustness against moisture sensitivity.
