UPS2W101MRD

The UPS2W101MRD is a miniature, low‑impedance aluminum electrolytic capacitor in a radial‑lead can intended for switching power supplies and general‑purpose power applications. Manufactured by Nichicon, this polarized capacitor pairs a high 450 V rating with a 100 µF capacitance for high‑voltage DC filtering and energy‑storage tasks.

Designed for compact assemblies, the UPS2W101MRD delivers specified ripple handling and long‑term endurance at elevated temperatures while meeting RoHS requirements.

Key Features

• Electrical Performance — 100 µF nominal capacitance with ±20% tolerance and a 450 V rated voltage suitable for high‑voltage DC applications.
• Low Impedance & Ripple Handling — Rated ripple currents of 350 mA at 120 Hz and 560 mA at 10 kHz provide reliable AC ripple absorption for switching environments.
• Thermal and Endurance Characteristics — Operational from −25°C to 105°C with a rated lifetime of 3000 hours at 105°C, supporting sustained use under elevated temperature and bias conditions.
• Radial Can Package — Radial lead, can‑style package with a lead spacing of 1.25 cm and physical dimensions L: 5 × D: 2.5 cm; polarized construction for through‑hole mounting.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple suppression in high‑voltage switching regulators and power conversion stages.
• High‑Voltage DC Filtering — Energy storage and DC‑link filtering where a 450 V rated capacitor is required to stabilize DC rails.
• General‑Purpose Power Electronics — Through‑hole radial mounting for power assemblies that require compact, high‑voltage electrolytic capacitance.

Unique Advantages

• High Voltage Capability: 450 V rating enables use in higher DC‑bus and high‑voltage filter applications without series stacking.
• Compact, Radial Footprint: Miniature can package with 1.25 cm lead spacing and L: 5 × D: 2.5 cm dimension supports space‑constrained through‑hole designs.
• Designed for Switching Environments: Low‑impedance construction and specified ripple currents at 120 Hz and 10 kHz improve stability and reduce thermal stress under switching ripple.
• Elevated Temperature Endurance: Rated for operation to 105°C with a 3000‑hour endurance at that temperature, supporting long‑term reliability in warm operating environments.
• RoHS Compliance: Meets RoHS directive (2011/65/EU,(EU)2015/863) for regulated substance limits.
