Parametric fit for filter and bias-T applications
The LQH32MN221J23L is a 220 µH drum-core wirewound inductor in Murata's LQH32 series, rated for 65 mA continuous current with a maximum DC resistance of 11.8 Ohm.
Frequency response and Q factor
The self-resonant frequency is 5.5 MHz, and the Q factor measures 40 at 796 kHz — this inductor is tuned for use in the low-MHz band where the Q peak aligns with the test frequency. Inductance is tested at 1 MHz, confirming the core material and winding geometry are optimized for switching frequencies and filter poles in that range.
Package and board-level integration
The unshielded drum-core construction means the magnetic field radiates; adjacent traces carrying sensitive analog signals should be kept at least one package width away to avoid coupling.
Sourcing and lifecycle posture
Available in Tape & Reel and Cut Tape options; sourcing is confirmed per RFQ with full lot traceability from the authorized channel.
