Operating temperature: -40ºC to +85ºC. Electrical specifications at +25ºC. Inductance measured on the HP4284A LCR meter. DCR measured on the 502BC milli-ohm meter. Inductance drops no more than 10% at rated I sat. Temperature rises Δ t < 15ºC (typical) at rated I rms. Inductance and Current Range: From 1.0 uH (1000 mA) to 560 uH (60 mA) SRF: From 3.4 MHz to 96 MHz Suitable for IR re-flows soldering. Tape and reel packing. MSL: Level 1. D. Applications: 1. 2. 3. 4. 5. Power supply line chokes. DC-DC Converters. Notebooks. Filters. Telecommunication devices. Frontier Electronics Corp.® http://www.frontierusa.com Page 1 of 1 667 E.
