UPW2W101MRD

The UPW2W101MRD is a radial‑lead aluminum electrolytic capacitor designed for miniature, low‑impedance energy storage in high‑voltage power systems. It delivers 100 µF at a 450 V rating in a compact can package, targeting switching power supplies and automotive power electronics.

Built for elevated operating conditions, the part offers high reliability with AEC‑Q200 qualification and an 8,000‑hour lifetime at 105°C, making it suitable for applications that demand sustained performance under thermal and electrical stress.

Key Features

• Electrical specification — 100 µF capacitance with a 450 V rated voltage and ±20% tolerance for bulk energy storage and DC link filtering.
• Low impedance and ripple capability — Specified ripple handling of 350 mA at 120 Hz and 560 mA at 10 kHz to support high‑frequency switching environments.
• Thermal endurance — Rated operating temperature range of −25°C to 105°C with a lifetime rating of 8,000 hours at 105°C.
• Automotive qualification — AEC‑Q200 rating and explicit application for automotive use cases where industry reliability standards are required.
• Mechanical and mounting — Radial, can package with radial lead mounting and 1.25 cm lead spacing for through‑hole assembly; physical dimensions L: 5 × D: 2.5 cm.
• Polarized design — Polarized aluminum electrolytic construction for DC applications requiring axial/radial bulk capacitance.

Typical Applications

• Switching power supplies — Bulk and DC link filtering where low impedance and high voltage handling reduce ripple and improve regulator stability.
• Automotive power electronics — Energy storage and smoothing in automotive modules; AEC‑Q200 qualification addresses automotive reliability requirements.
• High‑voltage power modules — Capacitor banks and power conversion assemblies that require compact high‑voltage capacitors with defined ripple performance.

Unique Advantages

• High voltage capacity: 450 V rating enables use in higher DC bus and power conversion applications without series stacking.
• Long‑term thermal reliability: 8,000 hours at 105°C rated lifetime supports sustained operation in thermally demanding environments.
• Automotive‑grade qualification: AEC‑Q200 rating aligns the component with automotive design and qualification workflows.
• Compact footprint: 5 × 2.5 cm size and radial lead mounting provide a space‑efficient form factor for through‑hole assemblies.
• Specified ripple performance: Rated ripple currents at 120 Hz and 10 kHz give clear guidance for thermal and ripple budgeting in power designs.
• Simple integration: Standard radial lead spacing (1.25 cm) and can package simplify mechanical mounting and PCB layout.
