Coilcraft, Inc. Surface Mount Wideband RF Transformers A9900-A

A9900-A is a surface mount wideband RF transformer with a 1:1 turns ratio, designed for impedance matching, balanced/unbalanced mixing, power splitting, coupling, and signal inversion. It operates from 0.525 MHz to 1000 MHz with a maximum insertion loss of 1.20 dB. The transformer has a primary and secondary inductance of 7.0 μH and a DC resistance max of 200 mΩ on each winding. It supports a maximum current of 250 mA, operates from -40°C to +85°C, and is rated for three reflows at 260°C. The component weighs 168 mg and is packaged in 16 mm wide plastic tape on a 13-inch reel with 12 mm pocket spacing. It meets MSL 1 moisture sensitivity and is suitable for aqueous PCB cleaning per MIL-STD-202 Method 215.
