ST121C126MAJ05 Description

Short technical summary and product information.

The ST121C126MAJ05 is a multilayer ceramic capacitor (MLCC) from Kyocera AVX's TurboCap series. It offers 12µF capacitance with ±20% tolerance, rated at 100V DC. The X7R dielectric provides stable capacitance over a temperature range of -55°C to +125°C with a ±15% capacitance change. This stacked SMD capacitor features a low ESL design, making it ideal for high-frequency filtering in switch mode power supplies (SMPS). The package is a Stacked SMD, 10 J-Lead with dimensions 14.61mm x 6.35mm and a maximum thickness of 3.56mm. Mounting is surface mount. Applications include SMPS input/output filtering, bypass, and decoupling circuits. The component is not RoHS compliant as per the datasheet.
