1812 CHIP INDUCTORS High-Reliability Chip Inductors MS450RAA ■ Higher SRF values than 1812 size parts with ferrite cores ■ 2% and 1% tolerances for all values ■ 9 inductance values from 1.0 to 4.7 µH Part number1 This robust version of Coilcraft’s standard 1812CS series features high temperature materials that allow operation in ambient temperatures up to 155°C. The leach-resistant base metalization with tin-lead (Sn-Pb) terminations ensures the best possible board adhesion.
