UHW1J122MHD

The UHW1J122MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized capacitor specified at 1200 µF and 63 V for general-purpose electronic designs.

Designed for applications that require high ripple current, low impedance at higher frequencies, and long operating life, this part delivers compact energy storage and filtration performance across a wide temperature range (−40 °C to 105 °C).

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 1.758 A at 120 Hz and high-frequency ripple capability of 2.93 A at 10 kHz, enabling robust handling of AC components on DC rails.
• Low Impedance and Low Loss — Impedance specified at 72 mΩ and tan δ (DF) of 0.09 (measured at 20 °C, 120 Hz), supporting efficient high-frequency performance.
• Long Endurance — Rated for 12,000 hours of operation at 105 °C under the series’ endurance conditions, providing extended service life in demanding thermal environments.
• Wide Temperature Range — Operates from −40 °C to 105 °C for versatile deployment across industrial and commercial designs.
• Compact Radial Can — Cylindrical can size φ16 × 30.5 mm length with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly.
• Controlled Leakage — Specified leakage current of 756 µA, measured per product conditions.
• RoHS Compliant — Conforms to RoHS requirements as noted in the product series documentation.

Typical Applications

• General-purpose electronic power circuits — Provides bulk energy storage and smoothing where high ripple current and compact size are required.
• Power supply filtering — Suited for DC rail decoupling and ripple suppression benefitting from low impedance and high-frequency ripple capability.
• Industrial and commercial equipment — Applicable in systems operating across −40 °C to 105 °C that need reliable, long-life electrolytic capacitors.

Unique Advantages

• High ripple current capability — Rated ripple currents of 1.758 A (120 Hz) and 2.93 A (10 kHz) reduce temperature rise and improve reliability under AC stress.
• Low high-frequency impedance — 72 mΩ impedance and a low tan δ (0.09) support better filtering and transient response at higher frequencies.
• Extended operational life — 12,000-hour endurance at 105 °C aligns with long-term deployment in thermally demanding environments.
• Small footprint, through-hole convenience — φ16 × 30.5 mm can with radial leads and 7.5 mm spacing enables compact PCB layouts and straightforward assembly in through-hole designs.
• predictable electrical characteristics — Specified capacitance tolerance (−20% to +20%), leakage current, and dissipation factor make design margining and thermal modeling more reliable.
• Regulatory compliance — RoHS status supports use in products that require restricted-substance compliance.
