UPW1C181MED

The UPW1C181MED is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for low impedance and high reliability in compact power designs. It provides 180 µF capacitance at a 16 V rating with performance characteristics targeted for switching power supplies and automotive electronics.

Its compact φ6.3 × 15 mm body, AEC-Q200 rating, and broad operating temperature range make the UPW1C181MED suitable for designs that require durable decoupling and ripple handling in space-constrained assemblies.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of −20% to +20%.
• Low Loss & Stability — tanδ of 0.16 (measured at 20°C, 120 Hz) for predictable AC characteristics and low dissipation in power circuits.
• Ripple Current Capability — 279.5 mA at 120 Hz (low frequency) and 430 mA at 10 kHz (high frequency), supporting switching regulators and power rail filtering.
• Leakage Current — 86.4 µA specified leakage after voltage application, suitable for power-supply and hold-up applications where controlled leakage is required.
• Temperature & Endurance — Operating range −55°C to +105°C with a rated endurance of 2000 hours at 105°C.
• Package & Mounting — Radial lead, polarized aluminum can construction; physical size φ6.3 × 15 mm (L: 1.5 × D: 0.63 cm), lead spacing 2.5 mm (±0.5 mm), packaged in bulk or bag packing (no terminal forming).
• Automotive-Grade Screening — AEC-Q200 rated, aligning the component with automotive electronics requirements where that rating is required.

Typical Applications

• Switching Power Supplies — Low impedance and high-frequency ripple handling make this capacitor suitable for input/output smoothing and decoupling in compact switch-mode power supplies.
• Automotive Electronics — AEC-Q200 rating and wide temperature range support use in vehicle control modules and auxiliary power circuits that demand reliability.
• Compact Power Modules — Small φ6.3 × 15 mm package and radial-lead mounting help minimize board space in compact DC/DC converters and power management modules.

Unique Advantages

• Compact, space-saving form factor: φ6.3 × 15 mm can reduce board area for high-density designs while still delivering 180 µF capacitance.
• Balanced ripple performance: Specified low- and high-frequency ripple current ratings (279.5 mA at 120 Hz; 430 mA at 10 kHz) enable reliable filtering across switching and ripple frequency ranges.
• Wide temperature margin for harsh environments: −55°C to +105°C operation and 2000 h endurance at 105°C provide predictable behavior in elevated-temperature applications.
• Predictable loss characteristics: tanδ = 0.16 at the rated voltage/frequency offering consistent dissipation behavior for power circuit design and thermal budgeting.
• Automotive-grade screening: AEC-Q200 rating provides a qualification baseline for automotive electronics projects requiring that screening.
• Flexible packaging: Available in bulk (no terminal forming) or bag packing to accommodate production and prototyping workflows.

Why Choose UPW1C181MED?

The UPW1C181MED combines Nichicon’s UPW series focus on low impedance and miniature sizing with concrete, verifiable specifications—180 µF at 16 V, defined ripple ratings, controlled leakage, and a wide −55°C to +105°C operating range. This makes it a practical choice for engineers specifying capacitors for compact switching supplies, automotive electronics, and space-constrained power modules where predictable electrical and thermal behavior matters.

Its radial-lead can package, AEC-Q200 screening, and documented endurance at elevated temperature support designs that need long-term robustness and repeatable performance across manufacturing and field conditions.
