Key Features

• Capacitance & Voltage — Rated at 220 µF with a 25 V working voltage, providing significant capacitance for compact SMD implementations.
• Tolerance & Polarization — Capacitance tolerance ±20% at 120 Hz, 20 °C; polarized design for correct circuit placement.
• Temperature Range & Endurance — Operating range −40 °C to +85 °C with endurance specified as 2000 hours at 85 °C under rated voltage (capacitance change within ±20% after test).
• Ripple Current — Rated ripple current of 250 mA at 120 Hz and 325 mA at 10 kHz to support smoothing and filtering duties in compact designs.
• Low-Temperature Stability — Impedance stability specified: Z(−25 °C)/Z(+20 °C) = 2 and Z(−40 °C)/Z(+20 °C) = 4 for the 25 V rating, measured at 120 Hz.
• Leakage Current — Leakage current specified as not more than 0.03 C·V (µA) after one minute at 20 °C, per datasheet formula.
• Package & Mounting — Radial can SMD package optimized for surface mounting on high-density PCBs and compatible with carrier-tape automated assembly.
• Standards & Marking — AEC-Q200 compliant and RoHS compliant; components are marked with black print on the case top for identification.

Typical Applications

• Automotive Electronics — AEC-Q200 compliance makes this capacitor suitable for electronic modules and control units within automotive systems.
• High-Density Surface-Mount Power Boards — Provides higher capacitance in a compact SMD can for power supply smoothing where board space is limited.
• Automated Assembly Lines — Designed for use with carrier-tape feed and pick-and-place equipment for efficient production runs.

Unique Advantages

• High volumetric capacitance — 220 µF delivered in a compact L:1 cm × D:1 cm package enables more capacitance per board area.
