IHLP1616BZER2R2M11

The IHLP1616BZER2R2M11 is a Vishay IHLP family shielded, surface-mount power inductor. The 1616 denotes the 16×16 mm footprint. The “B” is the series variant. The “2R2” indicates an inductance of 2.2 µH, with tolerance “M” meaning ±20%. It is designed for high-current DC-DC converter applications and offers low DC resistance in a compact, shielded package to help with EMI. Typical uses include step-down/up regulators in automotive, industrial, and consumer power supplies. Exact specs such as DCR, saturation current, and thermal limits depend on the specific device revision; consult the datasheet for precise values and packaging details (tape, reel, etc.).

Equivalents are any 2.2 µH, 1.6×1.6 mm low-profile power inductors with comparable saturation/Irms and DCR. Common cross-vendor families to check: Murata LQW/LQH series, TDK MLG/MLZ series, Würth Elektronik WE-MPS/WE-MPC, Bourns SRR series and Coilcraft’s other IHLP variants. Always verify inductance, Isat/Irms, DCR, DC bias curve and footprint before substituting.
