UPTW6680MHD

The UPTW6680MHD is a miniature aluminum electrolytic capacitor from Nichicon's UPT series, designed for high-voltage, high-ripple applications. It is a polarized, radial-lead can capacitor rated at 68 µF and 420 V, intended for general-purpose use including ballast applications where elevated ripple performance and extended service life are required.

Key value propositions include high ripple-current capability across a range of frequencies, a long endurance rating at elevated temperature, and RoHS compliance for restricted-substance requirements.

Key Features

• Capacitance & Rated Voltage — 68 µF nominal capacitance with a 420 V rated voltage, supplied with ±20% capacitance tolerance at 120 Hz, 20 °C.
• High Ripple Current — Rated ripple current of 510 mA at 120 Hz (105 °C) and 816 mA at 10 kHz; frequency coefficient data are provided for scaling ripple with frequency (1.00 at 120 Hz, 1.60 at 10 kHz).
• Long Life / Endurance — Endurance specified as 5000 hours at 105 °C with D.C. bias plus rated ripple current; after test the capacitor meets limits for capacitance change (within ±20%), tan δ, and leakage current.
• Temperature Range — Rated for operation from −40 °C to +105 °C.
• Package & Mounting — Radial lead, can-style package for through-hole mounting; lead spacing 7.5 mm and physical dimensions approximately L: 3.55 × D: 1.6 cm.
• Leakage & Dissipation — Leakage current specification: after 2 minutes at 20 °C, I ≤ 0.06 C V + 10 (µA). Maximum tan δ for 420 V units is 0.20 (measured at 120 Hz, 20 °C).
• Compliance — RoHS compliant (meets 2011/65/EU and (EU)2015/863 requirements as applicable to the UPT series).

Typical Applications

• Ballasts & Lighting — Suited for ballast applications where 420 V rating and high ripple handling are required.
• Power Supply Filtering — General-purpose smoothing and filtering in high-voltage DC supplies that require sustained ripple current and long operating life.
• Industrial Electronics — Replacement or design-in for industrial equipment needing durable, high-voltage electrolytic capacitors with defined endurance at elevated temperature.

Unique Advantages

• Compact high-voltage form factor: Delivers 68 µF at 420 V in a small radial-can package to save board area in through-hole designs.
• Measured ripple capability: Published ripple ratings at 120 Hz and 10 kHz, plus frequency coefficients, allow predictable thermal and ripple performance across application frequencies.
• Qualified endurance data: 5000-hour rating at 105 °C under rated conditions provides a clear baseline for expected long-term behavior in demanding environments.
• Controlled leakage and dissipation: Defined leakage-current formula and tan δ limits support predictable electrical performance during design and qualification.
• Regulatory readiness: RoHS compliance supports use in designs constrained by restricted-substance regulations.
