UPZW6680MHD

The UPZW6680MHD is a high-voltage, miniature aluminum electrolytic capacitor from Nichicon’s UPZ series designed for general-purpose applications requiring compact high-voltage capacitance. It features a 68 µF capacitance at a 420 V rating in a radial, can-style package optimized for designs that need reliable DC filtering and energy storage in a small footprint.

Key value comes from its high-voltage capability, broad operating temperature range (−40 °C to +105 °C), and specified endurance at elevated temperature, making it suitable for applications where long-term stability and ripple performance matter.

Key Features

• Rated Capacitance & Voltage — 68 µF capacitance rated for 420 V, providing substantial stored energy for high-voltage DC applications.
• Miniature Radial Can Package — Radial lead mounting with a 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for through-hole PCB layouts and tight spaces.
• Wide Operating Temperature — Specified for −40 °C to +105 °C to support outdoor, industrial, and general-purpose electronic environments.
• High-Temperature Endurance — Rated for 2000 hours at 105 °C under DC bias plus rated ripple current; capacitance change is specified to remain within ±20% after endurance testing.
• Ripple Current Performance — Rated ripple: 510 mA at 120 Hz (low frequency) and 765 mA at 10 kHz (high frequency), with frequency coefficients provided in the series datasheet for other frequencies.
• Leakage Current Specification — Leakage is guaranteed after 1 minute at 20 °C to be not more than 0.04CV + 100 μA (where C is µF and V is rated voltage), supporting predictable standby losses.
• Dissipation Factor (tan δ) — Maximum tan δ of 0.20 at the 420 V rating (measured at 120 Hz, 20 °C), enabling evaluation of AC losses for thermal and stability assessments.

Typical Applications

• High-voltage DC filtering — Smoothing and decoupling on high-voltage rails where a 420 V, 68 µF capacitor delivers bulk capacitance in a compact form.
• Power supply energy storage — Local energy reservoir for general-purpose power supplies and DC-DC stages requiring high-voltage capacitance.
• General-purpose electronic systems — Use where compact high-voltage capacitors with defined ripple and lifetime specifications are needed for reliable operation.

Unique Advantages

• Compact high-voltage solution — 420 V rating combined with a small radial can footprint gives designers high capacitance without a large board area.
• Defined high-temperature life — 2000 hours at 105 °C under rated conditions provides an explicit endurance expectation for thermal-stressed designs.
• Predictable ripple capability — Specified ripple currents at key frequencies (120 Hz and 10 kHz) and frequency coefficients in the series datasheet help size thermal management and placement.
• Measurable leakage behavior — Leakage current defined by the 0.04CV + 100 μA rule ensures designers can calculate standby losses precisely.
• Through-hole mounting simplicity — Radial lead configuration with 7.5 mm spacing supports robust mechanical mounting and easy prototyping or repair.
• Known dissipation characteristics — Maximum tan δ at rated voltage (0.20) aids in assessing AC losses and selecting complementary components.
