UVK2E101MHD

The UVK2E101MHD is a Nichicon UVK series aluminum electrolytic capacitor in a radial-lead can, offering 100 µF capacitance at a 250 V rating. It is a miniature-sized, general-purpose electrolytic designed for electronic equipment that requires bulk capacitance in a compact radial package.

With a rated temperature range of −40°C to 85°C, 2000-hour endurance at 85°C, and RoHS compliance, this part is suited for designs where compact size, voltage handling and sustained performance under elevated temperature are required.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 250 V rated voltage, suitable for higher-voltage bulk and smoothing applications.
• Size & Package — Miniature radial can package with dimensions φ16 × 25 mm and 7.5 mm lead spacing; supplied in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Temperature & Endurance — Operating range −40°C to 85°C and rated for 2000 hours at 85°C, with specified end-of-life limits for capacitance, dissipation factor and leakage current after endurance testing.
• Ripple Current Performance — Low-frequency ripple current 440 mA (120 Hz) and high-frequency ripple current 704 mA (10 kHz), supporting AC ripple handling across common power frequencies.
• Losses & Leakage — Tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz; specified leakage current of 1100 µA for the part as produced.
• Polarized, General-Purpose Design — Polarized electrolytic intended for general-purpose power and smoothing applications in electronic equipment.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in higher-voltage power supply stages where 100 µF at 250 V is required.
• Industrial control electronics — Energy storage and ripple suppression in compact control modules operating within −40°C to 85°C.
• General-purpose electronic equipment — Smoothing, decoupling and bulk capacitance functions in consumer and commercial devices that use radial-lead components.

Unique Advantages

• Compact, miniature case — φ16 × 25 mm footprint conserves PCB space while delivering 100 µF at 250 V.
• High voltage capability — 250 V rating enables use in circuits with elevated DC bus voltages without series stacking.
• Robust endurance — Qualified for 2000 hours at 85°C, providing predictable performance over extended elevated-temperature operation.
• Measurable ripple handling — Specified ripple currents at 120 Hz and 10 kHz (440 mA and 704 mA) let designers account for both low- and high-frequency stress.
• Known electrical characteristics — Specified tan δ (0.2 at 20°C, 120 Hz) and documented leakage current allow accurate circuit modeling and margining.
• RoHS compliant — Meets RoHS requirements for use in regulated regions and product lines.
