UPW1H3R3MDD

The UPW1H3R3MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series designed for compact power-electronic use. It delivers 3.3 µF capacitance at a 50 V rating in a miniature φ5 × 11 mm can, providing targeted decoupling and filtering for switching power supplies and related power rails.

Engineered for reliability across a wide operating range, this polarized capacitor supports -55 °C to 105 °C operation and meets AEC‑Q200 qualification, addressing demanding environments where size, stable performance, and lifecycle endurance matter.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a 50 V rated voltage and tolerance of -20% to +20%, suitable for localized energy storage and decoupling on 50 V rails.
• Low Loss — tanδ of 0.10 measured at 20 °C, 120 Hz, supporting efficient AC performance in ripple-prone circuits.
• Ripple Current Capability — Low-frequency ripple current of 19.5 mA at 120 Hz and high-frequency ripple current of 65 mA at 10 kHz for effective smoothing in switching applications.
• Low Leakage — Rated leakage current of 4.95 µA (measured condition per datasheet), minimizing standby losses and preserving bias integrity.
• High Temperature Endurance — Endurance rating of 2000 hours at 105 °C under rated conditions, supporting long-term operation in elevated-temperature environments.
• Compact Radial Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), provided in bulk or bag packing for through-hole placement and manual or automated assembly.
• Automotive-Grade Qualification — AEC‑Q200 rated, enabling use in automotive electronic modules and systems that require component-level qualification.

Typical Applications

• Switching Power Supplies — Local decoupling and output smoothing for compact switch-mode power supplies where low impedance and small footprint are required.
• DC-DC Converters — Bulk and output filtering on converters operating up to 50 V, benefiting from the part’s ripple-current characteristics.
• Automotive Electronic Modules — Use in control modules and subsystem boards where AEC‑Q200 qualification and wide temperature range are necessary.

Unique Advantages

• Miniature footprint: The φ5 × 11 mm radial can provides necessary capacitance while minimizing board space for dense power layouts.
• Series-level low-impedance design: UPW series heritage emphasizes low impedance for improved transient response in switching applications.
• Temperature and endurance performance: Rated for -55 °C to 105 °C with a 2000-hour life at 105 °C, enabling sustained operation in thermally demanding environments.
• Measurable ripple handling: Specified ripple-current values at both low and high frequencies support designers in thermal and reliability budgeting.
• Automotive qualification: AEC‑Q200 rating supports adoption in automotive electronics and other applications that require qualified components.
• Low leakage: Low leakage current helps preserve supply integrity in standby and low-current conditions.
