Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance.
• Snap‑in Terminal Package — Radial, can-style snap‑in mounting type for panel or PCB insertion in power assemblies.
• High Temperature Long Life — Rated endurance of 5000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Operating Temperature — Specified operating range from −25°C to +105°C.
• Ripple Current Ratings — Rated ripple current of 1.23 A at 120 Hz and 1.759 A at 50 kHz to support rectification and smoothing under load.
• Leakage Current Specification — Leakage current conforms to I ≤ 3√(C·V) µA after 5 minutes at 20°C (C: µF, V: V) as specified in the series datasheet.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Size — Physical dimensions: approximately L: 5.0 cm × D: 2.2 cm for space‑constrained power designs.

Typical Applications

• General Inverter Rectifier Circuits — Provides filtering and smoothing of rectified DC in inverter front ends.
• Switching Power Supplies — Used for bulk capacitance and ripple handling in switching regulator outputs and input filters.
• General-Purpose Power Filtering — Suitable for power conversion and smoothing in industrial and commercial power modules where long life at elevated temperature is required.

Unique Advantages

• Endurance at Elevated Temperature: Endurance rating of 5000 hours at 105°C under rated ripple current provides predictable life behavior for thermal-stressed power designs.
• High Voltage Capability: 400 V rating supports high-voltage rectifier and power conversion topologies common in inverter and PSU designs.
• Measured Ripple Performance: Specified ripple currents of 1.23 A (120 Hz) and 1.759 A (50 kHz) allow engineers to account for AC stress in design calculations.
• Leakage Current Defined: Leakage current bounded by I ≤ 3√(C·V) µA after stabilization, enabling predictable standby and no-load characteristics.
• Wide Operating Range: −25°C to +105°C operational range aligns with requirements for many power-electronics environments.
• Regulatory Compliance: RoHS conformity supports restricted‑substance requirements for commercial and industrial products.
