UHW1J121MPD6

The UHW1J121MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series in a radial lead can. It provides 120 µF capacitance at a 63 V rated voltage with a compact φ10 × 12.5 mm case and 5 mm lead spacing.

Designed for general-purpose electronic applications, this part emphasizes low impedance, high ripple-current capability, extended endurance at elevated temperature, and RoHS compliance.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low impedance — Specified impedance of 660 mΩ to support lower voltage drop and improved performance in filtering and decoupling roles.
• High ripple-current capability — Low-frequency ripple current 512 mA at 120 Hz and high-frequency ripple current 1.28 A at 10 kHz, with frequency coefficients defined by the UHW series.
• Long endurance — Life rating of 12,000 hours at 105°C under the specified endurance conditions for the series.
• Leakage and dissipation — Leakage current 75.6 µA (per part data) and tan δ of 0.09 at 120 Hz, 20°C for the 63 V rating.
• Compact radial package — φ10 × 12.5 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm) for through-hole designs.
• Polarized, can-style construction — Polarized aluminum electrolytic in a radial can package suitable for common PCB mounting patterns.
• Packaging & availability — Available in bulk (no terminal forming) and bag packing; part status: mass production.
• Environmental compliance — RoHS compliant per the product information.

Typical Applications

• General Purpose Electronics — Provides bulk decoupling and energy storage where a compact, polarized aluminum electrolytic is required.
• Power Supply Filtering — Suited to smoothing and ripple suppression tasks supported by the specified ripple-current ratings and low impedance.
• High-Density Assemblies — Small φ10 × 12.5 mm case fits space-constrained PCBs while delivering extended endurance at elevated temperatures.

Unique Advantages

• High ripple-current handling: 512 mA at 120 Hz and 1.28 A at 10 kHz reduce thermal stress in filtering and regulator outputs.
• Compact footprint: φ10 × 12.5 mm radial can and 5 mm lead spacing enable space-efficient through-hole placement.
• Long operational life: 12,000 hours at 105°C supports extended service intervals in continuous-duty environments.
• Low loss and leakage: tan δ of 0.09 and leakage current of 75.6 µA help maintain efficiency and predictable behavior in circuits.
• Manufacturing-ready packaging: Bulk or bag packing options simplify procurement for production runs.
• Regulatory compliance: RoHS conformity provides compliance for restricted substances requirements.
