The BU9S and BU9HS families are ideal for signal line applications; the others can be used in switching power supplies and power supply circuits. All provide significant attenuation of common mode noise across a broad range of frequencies. For height-restricted applications, the BU9 and BU9S filters are available in a horizontal configuration, which reduces their height to under half an inch (12.5 mm). For free evaluation samples, contact Coilcraft or request them on-line at **www.coilcraft.com.** ## **Core material** Ferrite **Terminations** RoHS compliant tin-silver over copper. Other terminations available at additional cost. **Weight** BU9: 3.1 – 4.1 g BU9H: 3.1 – 4.1 g BU9HS: 3.1 – 3.8 g BU9S: 3.1 – 3.8 g BU10: 6.3 – 6.9 g BU15: 14.6 – 16.1 g BU16: 15.1 – 18.0 g ## **Ambient temperature** –40°C to +125°C **Storage temperature** Component: –40°C to +125°C. Tray packaging: –40°C to +80°C **Moisture Sensitivity Level (MSL)** 1 (unlimited floor life at <30°C / 85% relative humidity) **Failures in Time (FIT) / Mean Time Between Failures (MTBF)** 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 **Packaging** BU9: 100 per tray BU9H: 100 per tray BU9HS: 100 per tray BU9S: 100 per tray BU10: 100 per tray BU15: 80 per tray BU16: 80 per tray **PCB washing** Tested with pure water or alcohol only. For other solvents, see Doc787_PCB_Washing.pdf.
