UPZW6151MHD

The UPZW6151MHD is a high-voltage, miniature-sized aluminum electrolytic capacitor from Nichicon's UPZ series. It is a radial-lead, polarized capacitor specified at 150 µF and 420 V, designed for general-purpose applications that require compact high-voltage capacitance with reliable ripple handling.

Key value propositions include a small ϕ18×40 mm can, rated performance across –40 °C to 105 °C, and 2,000 hours of endurance at 105 °C—offering a balance of voltage capability, temperature tolerance, and long-term stability for through-hole designs.

Key Features

• Capacitance & Tolerance — 150 µF nominal with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• High Rated Voltage — 420 V DC rating suitable for high-voltage circuits.
• Loss Tangent (tan δ) — tan δ = 0.20 measured at 20 °C, 120 Hz for predictable AC loss characteristics.
• Ripple Current Handling — Low-frequency ripple: 710 mA at 120 Hz; high-frequency ripple: 1.065 A at 10 kHz, enabling effective smoothing under AC or switching stress.
• Leakage Current — Specified leakage current of 2,620 µA (measurement condition referenced in product data).
• Operating Temperature & Endurance — Rated for −40 °C to 105 °C with a guaranteed endurance of 2,000 hours at 105 °C under rated conditions.
• Package & Mounting — Radial lead, polarized can package with lead spacing of 7.5 mm (±0.5 mm) for straightforward through-hole assembly.
• Compact Dimensions — Size φ18 × 40 mm (L: 4.0 cm × D: 1.8 cm) for space-efficient high-voltage designs.
• Packaging Options & Availability — Available in bulk (no terminal forming) and bag packing; status: mass production.

Typical Applications

• Power-supply filtering — Smoothing and bulk energy storage in high-voltage DC power supplies where a 420 V rated capacitor with strong ripple capability is required.
• Switch-mode power circuits — DC bus and snubber applications that benefit from the part’s specified high-frequency ripple current rating and tan δ behavior at 120 Hz.
• General-purpose high-voltage circuits — Through-hole designs requiring compact, polarized capacitors rated for elevated temperature and long endurance.

Unique Advantages

• Compact high-voltage footprint — φ18×40 mm can delivers 150 µF at 420 V in a space-efficient through-hole package.
• Designed for elevated temperatures — 2,000-hour endurance at 105 °C supports prolonged operation in thermally demanding environments.
• Clear ripple specifications — Separate low- and high-frequency ripple current ratings (710 mA at 120 Hz, 1.065 A at 10 kHz) make performance behavior easier to predict across switching frequencies.
• Predictable AC loss — tan δ specified (0.20 at 20 °C, 120 Hz) aids in thermal and loss calculations for system reliability planning.
• Through-hole convenience — Radial lead format and standardized 7.5 mm lead spacing simplify prototyping and PCB assembly for traditional designs.
• Production-ready supply — Mass-production status and multiple packing options support volume procurement and manufacturing flexibility.
