Gowanda’s 28M123J is a high-quality, reliable electronic component designed for demanding applications. This molded unshielded RF coil is part of the 28M series and features a compact design with dimensions of 22.86 × 7.137 × 7.137 mm and a weight of 2.65 g. It is suitable for through-hole technology (THT) mounting and is classified as a Commercial Off-The-Shelf (COTS) application grade. The coil offers an inductance of 120 µH with a Q minimum of 95, tested at a frequency of 0.79 MHz. It has a direct current resistance (DCR) of 4.1 Ω and a self-resonant frequency (SRF) of 10 MHz, with a current rating of 0.195 A DC. The dielectric withstanding voltage (DWV) is rated at 1000, 200, and it maintains a tolerance of ±5%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a powdered iron core. The component is not shielded but is designed to operate within a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) format and is fungal inert, ensuring durability and reliability in various environments.
