Small and lightweight surface mounting type. High Q at high frequency & High self-resonance frequency. For 15ºC Temperature Rise at 25ºC ambient. Inductance & Q measured with HP4291B Impedance Analyzer. SRF measured using the HP8720D or HP8753E Network Analyzer. DCR measured using the 16502 milliohm meter. Operating temperature: -40°C to +125ºC. This series has no color code due to the size is small. Inductance and Current Range: From 82 nH (1500mA) to 1200 nH (480 mA) SRF: From 230 MHz to 860 MHz MSL: Level 1. E. Applications: 1. 2. 3. 4. 5. 6.
