UCS2G150MHD

The UCS2G150MHD from Nichicon is a radial‑lead aluminum electrolytic capacitor designed for high‑voltage, high‑ripple applications. As a miniature, polarized radial can, it targets power supply and ballast uses as well as general‑purpose filtering in compact high‑voltage circuits.

Key value propositions include a 15 µF capacitance at 400 V rating, elevated ripple handling across a wide frequency range, and long‑life performance up to 10,000 hours at 105°C—providing reliable energy smoothing and decoupling in demanding environments.

Key Features

• Capacitance & Voltage — 15 µF rated capacitance at 400 V provides high‑voltage energy storage suitable for DC link, filtering and decoupling in power circuits.
• High Ripple Current Performance — Specified ripple current of 275 mA at 120 Hz and 550 mA at 100 kHz, with frequency coefficients available for scaling ripple across 50 Hz to ≥100 kHz operation.
• Long Life & High‑Temperature Endurance — Designed for 10,000 hours of load life at +105°C, supporting extended operation in elevated thermal environments.
• Loss and Leakage Characteristics — Series specifications include a tan δ limit of 0.24 at 400 V and a leakage current limit of 0.04CV + 100 µA after 1 minute at 20°C, enabling predictable loss and leakage behavior.
• Compact Radial Can Package — Miniature size (approx. 2.0 × 1.25 cm) with 5 mm lead spacing and radial lead mounting for through‑hole board designs where board space is constrained.
• Wide Operating Temperature Range — Rated for −40°C to +105°C to accommodate a broad set of ambient conditions.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product documentation.

Typical Applications

• Power Supplies and Converters — Bulk filtering and decoupling in high‑voltage DC link and switching supply stages where compact, high‑voltage capacitors are required.
• Ballasts and Lighting Circuits — Energy storage and ripple damping for electronic ballast and lamp drive applications, a use highlighted in the series documentation.
• Industrial Control Electronics — Filtering and transient suppression in industrial power control modules operating across a wide temperature range.
• General‑Purpose High‑Voltage Filtering — Polarized radial mount capacitor for smoothing and noise reduction in compact high‑voltage assemblies.

Unique Advantages

• High ripple capacity across frequency — Explicit ripple current ratings at both low and high frequencies plus frequency coefficients let designers size capacitors accurately for intended operating bandwidths.
• Documented long life at elevated temperature — 10,000‑hour endurance at 105°C supports reliability planning for products expected to operate hot for extended periods.
• Predictable electrical behavior — Published tan δ limits and a leakage current formula enable engineering calculations for loss, heating, and standby current.
• Space‑efficient radial-can form factor — Small footprint (2.0 × 1.25 cm) and 5 mm lead spacing make it suitable for through‑hole assemblies where board area is limited.
• Regulatory compliance — RoHS compliance supports use in regions and products requiring lead‑free materials.
