Coilcraft recommends a land pattern with a pad size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape to ensure proper soldering and to prevent solder from flowing onto the adjacent pads.
During reflow soldering, it's essential to ensure that the inductor is not exposed to excessive temperatures or thermal shock. Coilcraft recommends a peak reflow temperature of 260°C, with a dwell time of 20-30 seconds above 220°C.
The maximum current rating for the 1812FS-274JLC inductor is 2.4 A, based on a 40°C temperature rise. However, the actual current rating may vary depending on the operating frequency, temperature, and other environmental factors.
Yes, the 1812FS-274JLC inductor is designed for high-frequency applications, with a self-resonant frequency (SRF) of 150 MHz. However, the actual operating frequency range may vary depending on the specific application and circuit design.
The inductance value for the 1812FS-274JLC has a tolerance of ±5%, which means that the actual inductance value may vary by up to 5% from the nominal value of 27 μH.
