Active production, 27 µH at 125 mA
The LQH32MN270K23L is a Murata LQH32 series drum core wirewound inductor rated 27 µH at 1 MHz test frequency with ±10% tolerance. Current rating is 125 mA — the DC resistance of 3.1 Ohm max sets the I²R loss at full rated current to about 48 mW, which is within the 85°C ambient ceiling for this ferrite-core part. Self-resonant frequency is 13 MHz, so this inductor stays inductive well above the switching frequencies typical of DC-DC converters in the 1–5 MHz range.
Footprint and temperature envelope
Operating temperature range is -40°C to +85°C, covering industrial and most commercial environments without requiring derating below 85°C. The unshielded drum core construction means magnetic flux radiates — keep sensitive traces or other inductors at least one package width away to avoid coupling.
