Rated at 2.5A saturation current with low 55mOhm DCR, AEC-Q200 qualified. The multilayer ceramic construction provides a compact and reliable inductor solution for DC-DC converters and power management applications in automotive systems.","working_principle":"The VCHA105D-2R2MS6 operates as a passive multilayer chip inductor:\n\n1. Multilayer Construction: Multiple layers of ferrite ceramic and internal silver-palladium coil windings are co-fired to create a monolithic inductor structure. This provides a compact, magnetically shielded design with no external magnetic field leakage.\n\n2. Energy Storage: In DC-DC converter applications, the inductor stores energy during the switch-on period and releases it during the switch-off period, smoothing the output current. The 2.2uH value with 2.5A saturation current is suitable for buck converters switching at 500kHz-2MHz.\n\n3. Saturation Current: At 2.5A, the inductance drops by 30% from its nominal value. Below this current, the inductor maintains its specified inductance for proper DC-DC converter operation.\n\n4. Low DCR: The 55mOhm DC resistance minimizes I2R power loss. At 2A, the conduction loss is only 0.22W, contributing to high converter efficiency.\n\n5. AEC-Q200: Automotive qualification ensures the ferrite material and internal coil structure remain stable under thermal cycling and vibration.","pin_description":"\n
