UPS2W3R3MHD

The UPS2W3R3MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power filtering. It is a polarized, radial‑lead can type that delivers 3.3 µF capacitance at a 450 V rating in a compact package.

Built for applications that require high voltage capability in a small footprint, this RoHS‑compliant capacitor supports a wide operating temperature range and long life under elevated temperature conditions.

Key Features

• Electrical Performance — 3.3 µF nominal capacitance with a rated voltage of 450 V and polarization appropriate for DC power circuits; capacitance tolerance is ±20%.
• Low Ripple Capability — Rated ripple currents of 41 mA at 120 Hz and 65.6 mA at 10 kHz support smoothing and decoupling in switching supply outputs.
• Compact Radial Package — Radial lead, can‑style package with 5 mm lead spacing and overall dimensions approximately 20 mm × 12.5 mm (L × D), enabling space‑efficient board layouts.
• Wide Operating Temperature — Specified to operate from −25 °C to +105 °C to accommodate demanding thermal environments.
• Durability at Elevated Temperature — Rated lifetime of 3000 hours at 105 °C under specified conditions, supporting reliability in sustained high‑temperature operation.
• Standards Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), suitable for designs requiring restricted‑substance compliance.

Typical Applications

• Switching power supplies — Low impedance and rated ripple current make it suitable for input/output smoothing and decoupling in compact SMPS designs.
• General‑purpose power filtering — Polarized capacitor for DC bus smoothing and transient suppression in a variety of electronic power circuits.
• Compact power modules — Small can package and short lead spacing allow integration into space‑constrained power modules and assemblies.

Unique Advantages

• High voltage capability: 450 V rating lets designers use a single compact capacitor where higher DC voltage tolerance is required.
• Small footprint: Approximate dimensions of 20 mm × 12.5 mm and 5 mm lead spacing minimize PCB area compared with larger can‑type capacitors.
• Engineered for switching environments: Low impedance and specified ripple currents at 120 Hz and 10 kHz address common switching supply frequency ranges.
• Thermal endurance: 3000 hours at 105 °C provides a defined reliability metric for elevated‑temperature applications.
• RoHS compliant: Meets regulatory restricted‑substance requirements for modern electronic assemblies.
