Bulk decoupling for low-voltage rails
The TPSE158M002R0050: The 50 mOhm ESR limits self-heating under ripple current and keeps the voltage ripple within tight margins for digital loads. At 2.5 V rated, the part should be derated per standard tantalum practice — typically 50% of rated voltage for reliable operation, meaning a maximum applied DC voltage around 1.25 V for long-life applications.
Temperature range and deployment context
Rated for -55 °C to 125 °C, this capacitor covers the full industrial and automotive-adjacent temperature envelope. The molded case construction (type: Molded) provides mechanical stability and moisture resistance suitable for conformal-coated assemblies or environments with thermal cycling. This is a common PCB layout shared across multiple tantalum suppliers — a second-source qualification can reuse the same board without layout changes.
Lifecycle and sourcing posture
The TPS series is a standard product line with broad distribution coverage, so lead times and availability are typically stable for this form factor. Sourced to order against BOM quantities.
