UPT2W101MHD

The UPT2W101MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPT series. It is a radial-lead, polarized can-type capacitor specified at 100 µF and 450 V, designed for applications requiring high ripple tolerance and extended operational life.

Typical uses include ballast and general-purpose power applications where high-voltage handling, elevated-temperature endurance and compact radial packaging are required. The device is RoHS compliant and is available in bulk or bag packing for production use.

Key Features

• Capacitance and Voltage — 100 µF rated capacitance at 450 V, providing high-voltage energy storage in a compact form factor.
• High ripple current capability — Low-frequency ripple current 650 mA (120 Hz) and high-frequency ripple current 1.04 A (10 kHz), suitable for AC ballast and power conditioning applications.
• Long life at elevated temperature — Endurance rated 5000 hours at 105°C with specified limits for capacitance change, tan δ and leakage current after the endurance test.
• Loss characteristics — Tangent of loss angle (tan δ) 0.20 (measured at 20°C, 120 Hz, at 450 V rating) for predictable dissipation behavior.
• Leakage current specification — Leakage current listed as 2710 µA (measurement conditions per datasheet: after 2 minutes’ application of rated voltage at 20°C).
• Robust operating range — Operating temperature range from −40°C to +105°C for use in demanding environments.
• Compact radial package — Case size φ18 × 40 mm with radial lead spacing 7.5 mm (±0.5 mm), leaded can package for through-hole assemblies.
• Compliance and production status — RoHS compliant and in mass production to support volume manufacturing.

Typical Applications

• Ballasts and lighting power supplies — Handles the high-voltage and ripple requirements common in ballast circuits.
• Industrial power supplies — Provides bulk energy storage and ripple smoothing in medium- to high-voltage power modules.
• AC-to-DC conversion stages — Used for filtering and energy buffering where 450 V ratings and high ripple currents are required.

Unique Advantages

• High-voltage capability: 450 V rating enables direct use in higher-voltage circuits without series stacking or additional components.
• Elevated ripple tolerance: Specified ripple currents at both low and high frequencies reduce thermal stress and extend service life in ripple-heavy applications.
• Proven endurance: 5000 hours at 105°C provides predictable long-term behavior for designs that operate at elevated temperatures.
• Compact radial form: φ18 × 40 mm can with 7.5 mm lead spacing simplifies through-hole assembly while conserving board area.
• Measured electrical characteristics: Specified tan δ and leakage current values (measured at 20°C, 120 Hz) enable straightforward thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS compliance supports use in products targeting regulated markets.
