UPS1H331MPD

The UPS1H331MPD is a 330 µF, 50 V aluminum electrolytic capacitor from Nichicon's UPS series, designed as a miniature, low-impedance radial-lead capacitor for switching power supplies and general-purpose power applications. It delivers compact energy storage and ripple handling in a radial can package while meeting RoHS requirements.

Key characteristics include a wide operating temperature range from –55°C to 105°C, polarization for DC applications, and rated endurance of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 50 V rated voltage for mid-voltage DC power applications.
• Low Impedance — Specified impedance of 150 mΩ, supporting lower ripple voltage in power rails.
• High Ripple Current Capability — Rated ripple current of 575.1 mA at 120 Hz and 810 mA at 10 kHz to handle switching supply ripple.
• Wide Temperature Range — Operation from –55°C to 105°C for use across demanding thermal environments.
• Compact Radial Can Package — Radial lead mounting with 5 mm lead spacing and a compact 2 cm maximum seated height (L: 2 × D: 1 cm size) for space-constrained boards.
• Durability at Elevated Temperature — Rated lifetime of 2000 hours at 105°C under specified conditions.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Provides bulk capacitance and ripple smoothing for DC output stages in switching regulators.
• General-Purpose Power Filtering — Suitable for decoupling and filtering in general-purpose electronic power circuits where polarized electrolytic capacitance is required.
• Embedded and Industrial Electronics — Compact radial package and wide temperature range make it applicable to space-limited power rails in embedded and industrial designs.

Unique Advantages

• Compact footprint with substantial capacitance — 330 µF in a miniature radial can supports board space optimization without sacrificing energy storage.
• Low-impedance performance — 150 mΩ impedance helps reduce ripple voltage and improves transient response on power rails.
• High-frequency ripple handling — Rated ripple current up to 810 mA at 10 kHz supports modern switching regulator frequencies.
• Wide operating temperature — –55°C to 105°C rating enables use across a broad range of environmental conditions.
• Durability at elevated temperature — 2000-hour rating at 105°C provides predictable life in thermal-stressed applications.
• Regulatory compliance — RoHS compliance simplifies integration into assemblies requiring restricted-substance conformity.
