HA66 Shielded Surface Mount Inductors BI Technologies / TT Electronics HA66 Shielded Surface Mount Inductors are low profile, low-loss, ferrite-based inductors designed with a wide range of inductances and package sizes. The compact magnetically shielded inductors offer low DC resistance and high-saturation current. These HA66 inductors feature a low-pass DC filter and operate at a frequency range of up to 3MHz. The inductors operate from -40°C to +125°C temperature range. BI Technologies / TT Electronics HA66 inductors are ideal for a radar system, engine control, transmission control, DC-DC converters, automation system, and other high-power density applications where size is critical.
