UPZW6101MHD

The UPZW6101MHD is a miniature, high‑voltage aluminum electrolytic capacitor in Nichicon’s UPZ series designed for general‑purpose power electronics. It delivers 100 µF capacitance at a 420 V rating in a compact radial can package tailored for applications that require high working voltage in a small footprint.

Built for reliability under elevated temperatures, this polarized radial‑lead capacitor combines high ripple capability with a wide operating temperature range to support demanding smoothing and filtering tasks in compact power assemblies.

Key Features

• Rated Capacitance & Voltage — 100 µF capacitance with a 420 V rated voltage for high‑voltage, compact energy storage and smoothing.
• Electrical Characteristics — Capacitance tolerance ±20% (at 120 Hz, 20°C); tan δ ≤ 0.20 at 120 Hz for 420 V parts; leakage current specified as ≤ 0.04CV + 100 μA after 1 minute at 20°C (series specification).
• Ripple Performance — Rated ripple current 610 mA at 120 Hz and 915 mA at 10 kHz, supporting effective AC ripple handling across low and high frequencies.
• Temperature & Endurance — Operating temperature range −40°C to +105°C with endurance specified as 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Package & Mounting — Radial lead, can‑style package with 7.5 mm lead spacing; compact dimensions: L: 4 × D: 1.6 cm.
• Polarized Design — Polarized aluminum electrolytic suitable for conventional DC smoothing and energy storage in polarity‑defined circuits.

Typical Applications

• High‑Voltage Power Supplies — Provides bulk smoothing and energy storage where compact, high‑voltage capacitance is required.
• Switching Regulators and Converters — Handles ripple currents at both low and high frequencies to support DC‑DC conversion stages.
• Industrial Power Electronics — Suited for general‑purpose filtering and decoupling in compact assemblies operating up to 105°C.

Unique Advantages

• High Working Voltage: 420 V rating enables use in higher‑voltage circuits without increasing capacitor footprint.
• Compact Miniature Size: L: 4 × D: 1.6 cm radial can provides significant capacitance in a small package for space‑constrained designs.
• Robust Ripple Handling: Specified ripple currents of 610 mA at 120 Hz and 915 mA at 10 kHz support effective smoothing across frequencies.
• Wide Temperature Range and Endurance: −40°C to +105°C operation and 2000 h endurance at 105°C for sustained performance in elevated‑temperature environments.
• Predictable Leakage Behavior: Leakage current bounded by the series formula (≤ 0.04CV + 100 μA at 20°C after 1 minute), aiding margin calculations in design.
• Through‑Hole Mounting Simplicity: Radial lead configuration simplifies prototyping and assembly for through‑hole PCB applications.
