UHW1J182MHD

The UHW1J182MHD is a miniature aluminum electrolytic capacitor in a radial‑lead can, engineered for high reliability and elevated ripple handling in compact assemblies. It delivers 1.8 mF capacitance at a 63 V rating with low impedance characteristics and is offered in a φ16 × 40 mm case with 7.5 mm lead spacing.

Designed for general‑purpose electronic equipment, this part combines long endurance at elevated temperature with measurable high‑frequency performance, making it suitable where sustained ripple current, low loss (tan δ), and compact packaging are required.

Key Features

• Electrical Performance 1.8 mF capacitance with ±20% tolerance and rated voltage of 63 V; impedance specified at 60 mΩ.
• High Ripple Current Low‑frequency ripple current of 2.106 A at 120 Hz and high‑frequency ripple current of 3.51 A at 10 kHz, enabling robust AC current handling in compact form.
• Low Loss (tan δ) tan δ = 0.09 measured at 20°C, 120 Hz, 63 V, supporting efficient operation in AC and switching environments.
• Reliability & Endurance Rated endurance of 12,000 hours at 105°C under rated voltage and applied ripple, reflecting long service life in elevated‑temperature applications.
• Temperature Range Operates from −40°C to +105°C to cover a wide range of environmental conditions.
• Mechanical & Packaging Miniature radial can: φ16 × 40 mm (L: 4.0 cm × D: 1.6 cm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Leakage Current Specified leakage current of 1134 µA (measurement conditions per product specifications).
• RoHS Compliant Conforms to RoHS directive requirements.

Typical Applications

• General‑purpose electronic equipment Provides bulk capacitance and energy buffering where a compact, high‑reliability aluminum electrolytic capacitor is required.
• Circuits with significant ripple current Suited to assemblies that require sustained ripple handling and low impedance at both low and high frequencies.
• Compact power or control modules Small case size and radial‑lead packaging allow integration into space‑constrained modules while maintaining specified endurance at 105°C.

Unique Advantages

• High ripple capability: 2.106 A (120 Hz) and 3.51 A (10 kHz) ratings support demanding AC current conditions without oversized packaging.
• Low impedance and controlled loss: 60 mΩ impedance and tan δ = 0.09 (63 V, 120 Hz, 20°C) help minimize voltage drop and heating in high‑frequency environments.
• Extended high‑temperature life: 12,000 hours endurance at 105°C preserves performance over long duty cycles at elevated temperature.
• Compact radial can format: φ16 × 40 mm footprint with 7.5 mm lead spacing simplifies PCB layout in constrained designs.
• Clear specification set: Measured leakage current, ripple current, impedance, and tan δ values allow straightforward thermal and reliability planning.
• RoHS compliance: Meets environmental directive requirements for restricted substances.
