Key Features

• Capacitance & Tolerance — 22 µF nominal capacitance with tolerance of -20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage — 80 V continuous rated voltage for higher-voltage SMD applications.
• Low Loss & Dielectric — Tangent of loss angle (tan δ) 0.12 at 20°C, 120 Hz, enabling low dissipation in application.
• Low ESR & High Ripple Handling — ESR 40 mΩ at 100 kHz; low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) for demanding ripple environments.
• Leakage Current — Rated leakage current up to 100 µA.
• Temperature Range & Endurance — Operating temperature range −55°C to +125°C with a rated life of 3000 hours at 125°C.
• Package & Mounting — Surface-mount radial can (SMD) with dimensions φ8 × 7.7 mm; supplied in embossed carrier taping with moisture-proof packing for production assembly.
• Assembly Compatibility — SMD type compatible with lead-free reflow soldering conditions (peak temperature correspondence documented in series datasheet).
• Polarized — Polarized electrolytic capacitor suitable for DC applications.
• Regulatory — Series documentation indicates compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling and smoothing — Low ESR and high ripple current capability make this capacitor suitable for bulk filtering and output smoothing in power rails.
• Switching regulators and DC–DC converters — High-frequency ripple handling and low tan δ support stable performance in switching power circuits.
• Embedded and industrial electronics — Long life at elevated temperature (3000 h at 125°C) fits compact boards operating in harsher thermal environments.

Unique Advantages

• High thermal endurance: Rated for 3000 hours at 125°C, providing predictable lifetime performance in elevated-temperature applications.
• Efficient high-frequency performance: ESR of 40 mΩ at 100 kHz and 1.1 A high-frequency ripple current support reduced losses in switching circuits.
• Compact SMD can: φ8 × 7.7 mm radial SMD package delivers high capacitance in a small board footprint for space-constrained designs.
• Low dissipation: tan δ of 0.12 at 20°C, 120 Hz helps minimize heat generation under AC stress.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated pick-and-place and reflow assembly.
• RoHS-compliant series: Documented compliance with applicable RoHS directives supports regulatory needs in many markets.
