Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• Conductive Polymer Construction — Solid conductive polymer electrolyte provides low ESR and stable performance as indicated by a tanδ of 0.12 (20°C, 120 Hz).
• Low ESR — ESR specified at 22 mΩ measured at 20°C/100 kHz to support efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current of 310 mA at 120 Hz and high-frequency ripple current of 3.1 A at 300 kHz for demanding ripple conditions.
• Endurance & Temperature Range — Rated for 2000 hours at 105°C and specified to operate from -55°C to 105°C.
• Leakage Current — Specified leakage current up to 500 µA (measured after 2 minutes’ application of rated voltage at 20°C as per datasheet guidance).
• Compact SMD Can — Case size φ6.3 × 7.7 mm (L × D) with surface-mount land recommendation of 6.5 × 6.5 mm, suitable for space-constrained board designs.
• Production Packaging — Supplied in embossed carrier taping with moisture-proof packing for automated SMT assembly and handling.
• Regulatory Status — RoHS compliant.

Typical Applications

• General-purpose electronics — Applicable where a low-ESR, high-capacitance SMD capacitor is required for general-purpose power conditioning and decoupling in assemblies.
• Surface-mount assemblies — Designed for reflow-compatible SMD mounting and supplied in tape-and-reel style embossed carrier packaging for automated placement.
• High-temperature operation — Useful in designs that must tolerate environments up to 105°C and require verified endurance (2000 hours at 105°C).
• Compact board designs — Compact φ6.3 × 7.7 mm package supports dense PCB layouts while providing significant capacitance and ripple handling.

Unique Advantages

• Low ESR for improved power performance: 22 mΩ ESR at 100 kHz helps reduce losses and supports stable high-frequency operation.
• High ripple-current handling: Rated for 3.1 A at 300 kHz and 310 mA at 120 Hz, enabling reliable smoothing under varying ripple conditions.
• Robust thermal endurance: 2000-hour life at 105°C and a -55°C to 105°C operating range deliver predictable performance across wide temperature swings.
• Solid polymer reliability: Conductive polymer solid electrolyte with a specified tanδ of 0.12 (20°C, 120 Hz) for consistent loss characteristics.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing supports automated SMT lines and inventory handling.
• Regulatory compliance: RoHS compliant for use in compliant manufacturing environments.
