UCPW6151MHD

The UCPW6151MHD is a high-voltage, miniature-sized aluminum electrolytic capacitor in a radial-lead can designed for general-purpose high-voltage applications. It delivers 150 µF capacitance at a 420 V rating with long-life assurance specified to 10,000 hours at 105 °C.

This polarized radial-lead part combines high rated voltage, robust ripple handling and compact packaging (φ18 × 35.5 mm) for applications that require compact energy storage and smoothing in high-voltage circuits.

Key Features

• High voltage capability — Rated at 420 V to support high-voltage circuits within the UCP series range (400–450 V).
• Compact radial can package — φ18 × 35.5 mm case with 7.5 mm lead spacing provides a small footprint for a 150 µF, 420 V capacitor.
• Long endurance — Specified endurance of 10,000 hours at 105 °C under DC bias plus rated ripple current; capacitance change expected within ±20% after endurance test.
• Ripple current performance — 920 mA at 120 Hz (105 °C) and 1.38 A at 10 kHz, with the series’ published frequency coefficients (120 Hz = 1.00, ≥10 kHz = 1.50) for ripple scaling.
• Leakage and loss characteristics — Measured leakage current 2,620 µA (after 1 minute at 20 °C per product listing) and tan δ max 0.24 at the 420 V rating for predictable loss behavior.
• Wide operating temperature — Rated for operation from −40 °C to +105 °C for thermal robustness in elevated-temperature environments.
• Polarized radial-lead mounting — Through-hole radial leads (lead diameter 0.8 mm) for conventional PCB insertion and reliable mechanical retention.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to suit production handling preferences.

Typical Applications

• High-voltage power electronics — Bulk energy storage and smoothing in high-voltage stages where 420 V rated capacitance is required.
• Industrial equipment — Long-life filtering and decoupling in industrial power modules operating up to 105 °C.
• Power conversion — Support for high-voltage DC link or intermediate bus circuits that require compact high-voltage capacitors.

Unique Advantages

• High-voltage, compact form factor: 150 µF at 420 V in a φ18 × 35.5 mm package enables space-efficient placement of high-voltage capacitance.
• Designed for elevated-temperature duty: 10,000-hour rated endurance at 105 °C provides predictable ageing behavior in hot operating environments.
• Robust ripple capability: Specified ripple currents at both 120 Hz and 10 kHz, plus clear frequency coefficients, make ripple planning straightforward across frequency ranges.
• Measured electrical parameters: Published leakage current and tan δ at the rated voltage allow engineering-level verification during design and qualification.
• Through-hole mounting simplicity: Radial leads with standard 7.5 mm spacing simplify insertion and mechanical fixing for legacy and industrial PCBs.
