UHW0J122MPD

The UHW0J122MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, delivering 1200 µF capacitance at a 6.3 V rating in a compact φ10 × 12.5 mm can. It is designed for applications that require high ripple current capability and reliable long-term operation across a wide temperature range.

Part of the UHW series, this unit emphasizes lower impedance at high frequency, a small case size, and high ripple current handling for general-purpose electronic designs.

Key Features

• Electrical Performance — 1.2 mF (1200 µF) capacitance with tolerance -20% to +20%, rated voltage 6.3 V, and polarization specified as polar.
• Low-loss Characteristics — tan δ = 0.21 measured at 20°C and 120 Hz for the 6.3 V rating, supporting low dissipation in AC conditions.
• High Ripple Current — Low-frequency ripple current of 1.02 A at 120 Hz and high-frequency ripple current of 1.7 A at 10 kHz, enabling robust ripple handling in power circuits.
• Impedance — Specified impedance of 150 mOhm, helping reduce voltage drop under load at relevant frequencies.
• Reliability and Lifetime — Endurance rating of 10,000 hours at 105°C (rating and test conditions per series specifications), with operating temperature range from -40°C to +105°C.
• Compact Radial Package — Radial lead can sized φ10 × 12.5 mm with 5 mm lead spacing (±0.5 mm), available in bulk/bag packing for through-hole assembly.
• Regulatory Compliance — RoHS compliant and in mass production.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in through-hole power circuitry where compact size and elevated ripple handling are required.
• DC supply stabilization — Energy storage and ripple attenuation in low-voltage DC supplies and regulator output stages that operate within the 6.3 V rating.
• High-frequency decoupling — Use in circuits benefiting from the UHW series’ lower impedance at higher frequencies and the specified high-frequency ripple current performance.

Unique Advantages

• Compact footprint with high capability: The φ10 × 12.5 mm radial can packs 1200 µF and rated ripple currents into a small through-hole package to save board space.
• Designed for elevated ripple: Specified 1.02 A (120 Hz) and 1.7 A (10 kHz) ripple currents reduce thermal stress and support continuous operation under ripple load.
• Wide operating temperature range: Rated from -40°C to +105°C to accommodate designs exposed to broad ambient conditions.
• Long endurance at high temperature: 10,000 hours life rating at 105°C provides predictable longevity for thermal stress-prone applications.
• Low dissipation factor and impedance: tan δ = 0.21 (6.3 V, 120 Hz) and 150 mOhm impedance help minimize losses and voltage excursions under AC conditions.
• Production-ready packaging: Available in bulk/bag packing and listed as mass production for streamlined procurement and assembly.
