The Taiyo Yuden CBC3225T102KR is a wirewound chip power inductor from the CB series, designed for telecommunications infrastructure, industrial equipment, and medical devices. It provides 1000uH inductance with +-10% tolerance in a compact 1210 (3225 metric) surface-mount package. The ferrite core construction ensures stable inductance characteristics, while the semi-shielded design minimizes electromagnetic interference with adjacent components. With a saturation current rating of 100mA and temperature rise current of 75mA, this inductor is suitable for DC-DC converter filtering and power line noise suppression. The device is halogen-free and fully RoHS compliant, meeting modern environmental requirements.

The CBC3225T102KR operates as a passive inductive component with three key characteristics: 1) Energy Storage: When current flows through the wirewound coil, energy is stored in the magnetic field of the ferrite core. The 1000uH inductance value determines the rate of current change for a given applied voltage (V = L x di/dt). 2) Filtering: The inductor impedance increases with frequency (Z = 2 x pi x f x L), allowing it to present high impedance to AC ripple while passing DC current. This makes it effective for filtering switching noise from DC-DC converters and power supply lines. 3) Self-Resonance: At frequencies above 1.6MHz, the parasitic capacitance between windings resonates with the inductance, creating a self-resonant frequency beyond which the component behaves capacitively.
