Bourns SRP1770TA-100M Ultra High-Current Shielded Power Inductor (10µH, 16.5A, 11.8mΩ max, SMD)

Power up heavy-duty switching supplies and high-density VRMs with the genuine SRP1770TA-100M ultra high-current shielded power inductor from Bourns. Delivering 10 µH inductance in a massive 17 x 17 mm footprint with a 7.0 mm height profile, this AEC-Q200 qualified component handles continuous operating currents up to 16.5 A (and saturation peaks up to 22 A) with an ultra-low DC resistance of just 11.8 mΩ.

Constructed with a metal alloy powder core, the SRP1770TA series provides excellent soft saturation performance to handle high transient current surges without collapsing. Its fully shielded design prevents magnetic flux leakage, ensuring low EMI and whisper-quiet operation in automotive power distribution networks, server motherboards, high-power DC-DC buck/boost converters, and industrial automation equipment.

Key Features:

• AEC-Q200 Qualified: High-reliability automotive grade component built for extreme temperatures and heavy duty cycles.

• Ultra High Current Handling (16.5A Irms / 22A Isat): Engineered for power-hungry multi-phase power stages and VRMs.

• Ultra-Low DCR (<= 11.8 mΩ): Dramatically reduces I²R copper losses to maintain maximum system efficiency and minimal thermal buildup.

• Shielded Metal Alloy Core: Excellent EMI suppression and soft saturation characteristics under heavy electrical loads.
