UPHW6121MHD6

The UPHW6121MHD6 is a high‑voltage, miniature aluminum electrolytic capacitor in a radial‑lead can package designed for general purpose and ballast power applications. It provides 120 µF capacitance at a 420 V rating with a compact footprint and polarized radial lead termination.

Key value propositions include high ripple current capability, a load life rated for 2000 hours at 105°C, and RoHS compliance, making it suitable for power‑filtering and energy‑storage roles in high‑voltage power designs.

Key Features

• Electrical Performance — 120 µF nominal capacitance with a rated voltage of 420 V and capacitance tolerance of ±20% (at 120 Hz, 20°C); polarized construction for DC applications.
• High Ripple Current — Rated ripple current of 800 mA at 120 Hz and 1.2 A at 10 kHz, enabling effective smoothing and ripple handling in high‑voltage circuits.
• Endurance and Reliability — Load life of 2000 hours at 105°C under DC bias plus rated ripple current. Endurance specification requires capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after the test.
• Thermal Range — Operating temperature range from −40°C to +105°C, supporting elevated operating temperatures common in power electronics.
• Loss and Leakage Characteristics — For the 420 V rating, tan δ is specified up to 0.20 (max); leakage current specification: after 1 minute at 20°C the leakage current is ≤ 0.04CV + 100 µA.
• Mechanical & Package — Radial, can‑style package with 7.5 mm lead spacing, seated height up to 1.24 inch, and part dimensions L: 3.15 × D: 1.8 cm for compact through‑hole mounting.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Ballast and Lighting Power Supplies — Used for energy storage and ripple suppression in high‑voltage lamp ballast circuits where 420 V rating and long life at elevated temperature are required.
• High‑Voltage Power Supplies — Provides bulk capacitance and smoothing in DC link and high‑voltage filtering stages.
• Industrial Power Modules — Compact, high‑voltage DC filtering for equipment that requires reliable ripple handling and endurance at 105°C.

Unique Advantages

• High ripple capability: 800 mA at 120 Hz and 1.2 A at 10 kHz support demanding AC ripple environments without overspecifying component footprint.
• Long elevated‑temperature life: 2000 hours at 105°C under rated conditions gives predictable aging and replacement intervals for high‑temperature installations.
• Compact high‑voltage form factor: 120 µF at 420 V in a radial can with 3.15 × 1.8 cm footprint helps conserve PCB/assembly space while meeting high‑voltage needs.
• Clear electrical limits: Specified tan δ (0.20 max at 420 V) and a defined leakage current formula (≤ 0.04CV + 100 µA after 1 minute at 20°C) make performance predictable for design calculations.
• Through‑hole mounting simplicity: Radial lead and 7.5 mm lead spacing facilitate robust mechanical mounting and easy replacement in repairable equipment.
• RoHS compliant: Materials and construction meet the RoHS directive (2011/65/EU, (EU)2015/863) requirements for environmental compliance.
