UPTW6121MHD

The UPTW6121MHD is a polarized aluminum electrolytic capacitor from Nichicon's UPT series. It provides 120 µF capacitance at a 420 V rating in a compact radial-can package, designed for general-purpose and ballast applications where high ripple capability and long operational life are required.

Engineered as a radial-lead through-hole component, the UPTW6121MHD combines high ripple-current performance with a wide operating temperature range (−40°C to +105°C) and RoHS compliance for easy integration into industrial and power-electronic designs.

Key Features

• Electrical performance — 120 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance; polarized device suitable for DC high-voltage applications.
• High ripple-current capability — Rated ripple current of 660 mA at 120 Hz and 1.056 A at 10 kHz, supporting demanding AC/rectified current environments.
• Long life at elevated temperature — Specified endurance of 5000 hours at 105°C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current after test.
• Wide operating temperature — Specified from −40°C to +105°C to cover many industrial environments.
• Package and mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 4 × D: 1.8 cm) for through-hole assemblies and retrofit designs.
• Leakage and dissipation characteristics — Leakage current specified by 0.06CV+10 (μA) after 2 minutes at 20°C; series tan δ limits apply (for 420 V, tan δ max. 0.20) for predictable dissipation behavior.
• Regulatory — RoHS compliant.

Typical Applications

• Ballast and lighting electronics — Suited for ballast applications where high ripple current handling is required.
• High-voltage power supplies — 420 V rating and strong ripple capability make it suitable for filtering and energy storage in high-voltage DC circuits.
• Industrial power electronics — Useful in general-purpose industrial equipment that requires long life at elevated ambient temperatures and reliable through-hole mounting.
• General-purpose electronic designs — A compact radial electrolytic solution for designs needing polarized high-voltage capacitance with defined endurance characteristics.

Unique Advantages

• Compact high-voltage solution — 120 µF at 420 V in a small radial-can footprint (L: 4 × D: 1.8 cm) saves board space in through-hole assemblies.
• High ripple tolerance — Measured ripple ratings at 120 Hz and 10 kHz support a range of rectified and high-frequency ripple environments.
• Proven long-term performance — Endurance specified to 5000 hours at 105°C under rated conditions provides predictable lifecycle behavior for maintenance planning.
• Predictable leakage and dissipation — Clear leakage current formula and tan δ limits enable reliable thermal and leakage budgeting in design.
• Through-hole, easy-to-fit package — Radial leads with 7.5 mm spacing simplify assembly and retrofit into existing PCB layouts.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
