UCA2G100MPD

The UCA2G100MPD is a miniature aluminum electrolytic capacitor from Nichicon's UCA series, configured as a radial-lead, polarized can. It delivers 10 µF capacitance at a 400 V rating in a compact φ10×20 mm package with 5.0 mm lead spacing.

Designed for general-purpose high-voltage applications such as power supplies and ballasts, this part offers high ripple-current capability and long life: specified for 10,000 hours at 105°C. It is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a 400 V rated voltage, suitable for high-voltage filter and smoothing applications.
• High Ripple-Current Capability — Rated ripple currents of 140 mA at 120 Hz and 280 mA at 100 kHz, supporting power supply ripple handling across frequency ranges.
• Long Endurance — Load-life endurance specified at 10,000 hours at 105°C for the φ10 case size, providing predictable performance over extended operating periods.
• Low-Frequency Loss (tan δ) — tan δ of 0.20 measured at 20°C, 120 Hz (at 400 V), enabling assessment of dissipation and heating in design calculations.
• Leakage Current — Leakage current specified at 260 µA, useful for standby and leakage budgeting in high-voltage circuits.
• Compact Radial Package — φ10×20 mm can with 5.0 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies; packaged in bulk (no terminal forming) or bag packing.
• Operating Temperature Range — Rated from −25°C to +105°C to cover typical industrial temperature envelopes.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in high-voltage DC power supplies where 400 V rating and 10 µF capacitance are required.
• Ballasts — Energy storage and ripple suppression in ballast circuits, leveraging the part’s high ripple-current capability and long life at elevated temperature.
• High‑Voltage Electronics — General-purpose decoupling and filtering in high-voltage assemblies that require a compact radial electrolytic solution.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage rails without cascading multiple lower-voltage caps.
• Frequency-spanning ripple support: Defined ripple-current values at 120 Hz and 100 kHz permit accurate thermal and reliability budgeting across common ripple spectra.
• Predictable long-term performance: 10,000-hour endurance at 105°C for the φ10 case provides a clear specification for MTBF and maintenance planning.
• Compact radial form factor: φ10×20 mm can with standard 5 mm lead spacing simplifies PCB layout for through-hole designs while conserving board area.
• Application-ready packaging: Available in bulk or bag packing (no terminal forming) to support standard assembly and handling processes.
