UPW1V4R7MDD

The UPW1V4R7MDD is a miniature aluminum electrolytic capacitor in a radial‑lead can, offering 4.7 µF capacitance at a 35 V rating. Designed for low impedance and high reliability, it targets compact power designs such as switching power supplies and automotive electronics.

Key attributes include a small footprint (φ5 × 11 mm), a wide operating temperature range of −55 °C to 105 °C, and a rated endurance of 2000 hours at 105 °C, providing a balance of performance and durability for demanding power applications.

Key Features

• Capacitance & tolerance — 4.7 µF with tolerance of −20% to +20% for predictable bulk capacitance in compact circuits.
• Rated voltage — 35 V DC rating suitable for a wide range of low‑voltage power rails.
• Low loss (tan δ) — tanδ 0.12 measured at 20 °C, 120 Hz, supporting efficient energy handling in switching environments.
• Ripple current capability — 54 mA at 120 Hz and 180 mA at 10 kHz, enabling effective smoothing of low‑ and high‑frequency ripple components.
• Leakage current — Low leakage current measured at 4.935 µA, helping preserve efficiency in hold‑up and filter applications.
• Thermal and endurance rating — Operating range −55 °C to 105 °C with 2000 hours life at 105 °C for sustained performance under elevated temperature stress.
• Compact radial package — φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm) for through‑hole mounting in dense board layouts.
• Automotive grade — AEC‑Q200 rating listed in specifications for use in automotive applications where component qualification is required.

Typical Applications

• Switching power supplies — Low impedance and compact size make the capacitor suitable for output smoothing and decoupling in switching regulators.
• Automotive electronics — AEC‑Q200 qualification and wide temperature range support use in automotive control modules and power subsystems.
• DC‑DC converters — 35 V rating and defined ripple current performance enable filtering and energy storage on converter input/output stages.
• General power filtering — Small form factor and low leakage current are useful for space‑constrained power filter networks and board‑level decoupling.

Unique Advantages

• Miniature footprint: φ5 × 11 mm can saves board space in compact designs while still delivering electrolytic capacitance.
• Broad frequency ripple handling: Distinct low‑ and high‑frequency ripple current ratings (54 mA @120 Hz, 180 mA @10 kHz) allow designers to quantify performance across operating conditions.
• High temperature endurance: 2000 hours at 105 °C offers predictable lifetime behavior for thermally stressed applications.
• Automotive qualification: AEC‑Q200 listing supports use where automotive component qualification is required.
• Through‑hole mounting convenience: Radial lead configuration and standard lead spacing simplify prototyping and assembly for PCB designs that prefer through‑hole components.
