UPW1H2R2MDD

The UPW1H2R2MDD is a miniature, radial-lead aluminum electrolytic capacitor designed for low‑impedance, high‑reliability power applications. It provides 2.2 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can and is optimized for switching power supply environments.

Targeted use cases include automotive and compact power electronics where defined endurance, frequency performance and a small footprint are required. The part carries an AEC‑Q200 rating and is specified for operation from −55°C to 105°C.

Key Features

• Capacitance & Voltage — 2.2 µF nominal capacitance rated at 50 V for decoupling and power‑supply stabilization in compact circuits.
• Low‑impedance construction — Series description notes miniature size with low impedance suitable for switching power supplies, improving transient response in power rails.
• Loss characteristics (tan δ) — tanδ of 0.10 measured at 20°C, 120 Hz (50 V rating), supporting predictable AC loss behavior.
• Ripple current capability — Low‑frequency ripple current 16.5 mA at 120 Hz and high‑frequency ripple current 55 mA at 10 kHz, enabling use where AC ripple is present.
• Low leakage — Leakage current of 4 µA after rated voltage application at 20°C for stable bias performance.
• Temperature & endurance — Rated for −55°C to 105°C with a life/endurance specification of 2000 hours at 105°C.
• Form factor & mounting — Radial lead, can package in φ5 × 11 mm dimensions with 2.0 mm lead spacing (±0.5 mm), suited to through‑hole PCB mounting.
• Packaging options — Available in Bulk (No Terminal Forming) or Bag Packing to fit different assembly workflows.
• Lifecycle status — Current product status: End Of Life.

Typical Applications

• Switching Power Supplies — Miniature, low‑impedance design helps stabilize switching rails and improve transient response in compact converters.
• Automotive Electronics — AEC‑Q200 rating and −55°C to 105°C operation make it suitable for automotive electronic modules that require qualification to automotive stress profiles.
• Compact, space‑constrained power circuits — φ5 × 11 mm can and radial lead format accommodate small power modules and tight PCB layouts requiring reliable capacitance and ripple handling.

Unique Advantages

• Miniature footprint: φ5 × 11 mm can size provides effective capacitance in minimal board area for compact designs.
• Validated high‑temperature endurance: 2000 hours at 105°C gives designers a quantified life target for thermal stress planning.
• AEC‑Q200 rating: Explicit AEC qualification supports usage in environments requiring automotive‑grade component reliability.
• Measurable ripple performance: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies allow predictable thermal and AC behavior in power applications.
• Low leakage and controlled dissipation: 4 µA leakage and tanδ = 0.10 at 120 Hz provide stable bias characteristics and predictable loss under normal operating conditions.
• Through‑hole radial mounting: Robust leaded can package eases handling and mechanical attachment in through‑hole assemblies.
