UHW1J180MDD

The UHW1J180MDD is a miniature, radial-lead aluminum electrolytic capacitor designed for high-reliability, high-ripple applications. It combines a compact φ5 × 11 mm can with engineering-focused performance characteristics for general-purpose electronic designs.

With a rated voltage of 63 V, 18 µF capacitance and low impedance at higher frequencies, this capacitor is targeted at circuits that require compact filtering and ripple-handling capability while operating across a wide temperature range.

Key Features

• Capacitance & Tolerance — 18 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 63 V working voltage suitable for mid-voltage power rails.
• Low Loss Factor — tanδ = 0.09 (max) at 20°C, 120 Hz, enabling predictable AC performance in filtering and decoupling applications.
• High Ripple Current Capability — Low-frequency ripple current 124 mA at 120 Hz and high-frequency ripple current 310 mA at 10 kHz, supporting designs with significant AC ripple content.
• Low Leakage — Specified leakage current of 11.34 µA, helping maintain low standby and bias currents in sensitive circuits.
• Compact Radial Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), ideal for dense PCB layouts using radial-leaded components.
• Wide Operating Temperature — Rated −40°C to +105°C to cover a broad range of environmental conditions.
• Long Endurance — Specified life/endurance of 8000 hours, providing durability in continuous-use applications.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Power Supplies — Compact smoothing and ripple suppression on mid-voltage rails where high ripple current capability and small footprint are required.
• DC-DC Converter Output Filtering — Provides low-impedance performance at higher frequencies to stabilize converter outputs and reduce voltage ripple.
• Industrial and Consumer Electronics — General-purpose decoupling and energy storage in compact modules that operate across −40°C to +105°C.
• PWM and High-Frequency Switching Circuits — Suitable where moderate high-frequency ripple handling is needed thanks to reduced impedance at higher frequencies.

Unique Advantages

• Compact, high-ripple design: φ5 × 11 mm package delivers significant ripple-handling (310 mA at 10 kHz) in a small footprint for space-constrained boards.
• Predictable AC performance: Low tanδ (0.09 at 20°C, 120 Hz) and datasheet frequency characteristics help designers size capacitance and ripple margins reliably.
• Low leakage current: 11.34 µA leakage supports applications that require low bias or standby currents.
• Wide operating temperature: −40°C to +105°C rating ensures consistent behavior across common industrial and consumer temperature ranges.
• Flexible procurement packaging: Bulk or bag packing accommodates different assembly and inventory workflows.
