Key Features

• Capacitance & Voltage: 56 µF capacitance rated at 25 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Conductive Polymer Electrolyte: Solid electrolytic construction for stable electrical characteristics, including a tan δ of 0.12 (20 °C, 120 Hz).
• Low ESR for High-Frequency Performance: ESR of 50 mΩ measured at 20 °C/100 kHz, supporting high-frequency decoupling and filtering.
• High Ripple Current Capability: Low-frequency ripple current 90 mA at 120 Hz and high-frequency ripple current 900 mA at 300 kHz for robust handling of transient and switching currents.
• Wide Temperature & Long Life: Operating temperature range –55 °C to 125 °C with a rated endurance of 3000 hours at 125 °C.
• Compact SMD Package: Radial can SMD package with dimensions φ6.3 × 5.8 mm and a recommended land size of 6.6 × 6.6 mm, supplied in embossed carrier tape with moisture-proof packing.
• Leakage Current: Specified leakage current up to 100 µA after standard conditioning.
• RoHS Compliant & Reflow Compatible: Conforms to RoHS; compatible with lead-free reflow soldering profiles (peak solder temperature up to 260 °C as specified for the series).

Typical Applications

• Power supply decoupling: Low ESR and high ripple capability make it suitable for smoothing and decoupling on DC power rails in switching regulators and point-of-load circuits.
• Switching power supplies and DC-DC converters: Handles high-frequency ripple currents common in converter outputs and bulk decoupling for regulator stages.
• Industrial and control electronics: Extended temperature range and long endurance support reliable operation in elevated-temperature environments.

Unique Advantages

• High-temperature endurance: 3000-hour life rating at 125 °C provides predictable aging and longer service life in thermally stressed designs.
• Superior HF performance: 50 mΩ ESR at 100 kHz and a defined tan δ support stable impedance at switching frequencies.
• Robust ripple handling: 900 mA high-frequency ripple rating enables reliable performance with modern, high-speed power converters.
• Space-efficient SMD can: φ6.3 × 5.8 mm footprint balances capacitance and board-space constraints for compact assemblies.
• Manufacturing-friendly packaging: Embossed carrier tape with moisture-proof packing and reflow compatibility simplify automated assembly and handling.
• Regulatory compliance: RoHS compliance supports deployment in regulated markets and designs.
