Key Features

• Capacitance & Voltage — 68 µF rated at 50 V with a capacitance tolerance of -20% to 20% appropriate for bulk decoupling and energy storage.
• Low ESR / High-Frequency Performance — ESR of 25 mΩ measured at 20°C/100 kHz and tanδ 0.12 (20°C, 120 Hz) to support high-frequency ripple handling and low loss operation.
• Ripple Current Capability — Low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz) for robust performance in switching power supplies and converter outputs.
• High Temperature Endurance — Rated for 3000 hours at 125°C, enabling extended life in elevated-temperature environments.
• Wide Operating Temperature Range — Specified for -55°C to 125°C to cover a broad range of operating conditions.
• SMD Can Package & Packaging — Radial can SMD package (φ10 × 12.4 mm) supplied in embossed carrier tape with moisture-proof packing for automated assembly and storage.
• Leakage Current — Specified leakage current of 170 µA after rated voltage application, suitable for general-purpose power applications.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supply decoupling — Low ESR and 1.6 A high-frequency ripple capability make it suitable for smoothing and decoupling on DC-DC converter outputs and intermediate rails.
• Switching power supplies — High allowable ripple current and solid electrolyte construction support reliable ripple handling in switching regulator outputs and bulk capacitance roles.
• Industrial electronics — Long life at elevated temperature (3000 h at 125°C) and wide operating range (-55°C to 125°C) suit control and instrumentation electronics operating in harsh environments.
• Telecommunications and networking — Compact SMD can package with low ESR supports high-frequency filtering and energy buffering in communication equipment power systems.

Unique Advantages

• Low ESR for efficient filtering: 25 mΩ ESR at 100 kHz reduces power loss and improves high-frequency stability in power rails.
• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz accommodate both switching and mains-frequency ripple demands.
• Robust high-temperature life: 3000 hours rated life at 125°C provides predictable aging and endurance for elevated-temperature installations.
• Compact SMD can form factor: φ10 × 12.4 mm size with embossed carrier taping supports automated placement while saving PCB area compared with larger through-hole alternatives.
• Controlled leakage and loss characteristics: 170 µA leakage and tanδ 0.12 at 120 Hz help maintain efficient, low-noise operation in sensitive power circuits.
• RoHS compliant supply chain: Meets RoHS directive requirements for lead-free assemblies and environmental compliance.
