Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 63 V rated voltage; capacitance tolerance ±20%.
• Loss Angle (tan δ) — tanδ = 0.25 (measured at 20°C, 120 Hz), providing a defined dissipation characteristic for design margin calculations.
• High Ripple Current Capability — Low-frequency ripple current 2.11 A at 120 Hz and high-frequency ripple current 2.4265 A at 50 kHz, enabling effective AC ripple handling in power circuits.
• Leakage Current — Specified leakage current 1230 µA after rated voltage application, useful for standby and leakage budgeting.
• Long Endurance — Rated for 3000 hours at 105°C with specifications restored after endurance testing, supporting designs requiring extended high-temperature operation.
• Operating Temperature Range — −40°C to 105°C, suitable for a wide range of industrial and commercial environments.
• Mechanical & Mounting — Snap-in terminal, radial can (φ25 × 35L) for secure PCB mounting and reliable mechanical retention.
• Packaging & Availability — Tray packing; status: mass production. RoHS compliant.

Typical Applications

• Power Supplies — Bulk filtering and smoothing where 2.7 mF at 63 V supports stable DC rails and energy buffering.
• DC/DC Converters and Power Modules — DC link and output filtering in converters that require high ripple current handling and thermal endurance.
• Industrial and Commercial Equipment — General-purpose energy storage in control systems and power electronics operating up to 105°C.

Unique Advantages

• Designed for High Ripple Environments: Specified low- and high-frequency ripple currents (2.11 A at 120 Hz, 2.4265 A at 50 kHz) reduce voltage ripple and thermal stress in power circuits.
• Long High-Temperature Endurance: 3000-hour rating at 105°C ensures consistent capacitance and dissipation behavior over extended operating periods.
• Clear Electrical Characterization: Defined tanδ (0.25 at 20°C, 120 Hz) and leakage current (1230 µA) simplify loss and leakage budgeting during design.
• Robust Mechanical Mounting: Snap-in radial can (φ25 × 35L) provides reliable PCB retention for automated assembly and vibration resistance.
• Production-Ready Packaging: Tray packing and mass-production status support scalable procurement and line-level assembly workflows.
• RoHS Compliant: Conforms to RoHS requirements for regulatory and environmental considerations.
