UPJ1H331MHD6

The UPJ1H331MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series. It delivers 330 µF at 50 V in a compact φ16 × 15 mm can with 7.5 mm lead spacing, designed for general-purpose power applications.

Built for switching power supplies and other power-electronics designs, this part combines low impedance, high ripple-current capability, and long-duration reliability with a rated endurance of 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 50 V with ±20% tolerance (at 120 Hz, 20°C).
• Low Loss — Tangent of loss angle (tanδ) specified at 0.10 under 20°C, 120 Hz test conditions for stable AC performance.
• High Ripple-Current Handling — Specified ripple current of 536.5 mA at 120 Hz and 925 mA at 200 kHz to support smoothing and decoupling in switched-mode power stages.
• Leakage Current — Leakage current specified at 495 µA, supporting predictable bias behavior after voltage application.
• Long Endurance — Rated for 5000 hours at 105°C under rated ripple and DC bias conditions to support extended field life.
• Wide Temperature Range — Operating range from −55°C to +105°C for use across varied environments.
• Radial Lead Mechanical Package — φ16 × 15 mm can with 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm), available in bulk or bag packing for easy through-hole assembly.
• RoHS Compliant — Conforms to RoHS directive as indicated in the product documentation.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple handling reduce voltage ripple and improve regulation stability.
• DC/DC Converters — Input and output decoupling for converters requiring compact capacitance at 50 V ratings.
• Industrial Power Electronics — Smoothing and energy storage in control and power modules operating across −55°C to +105°C.

Unique Advantages

• Low-Impedance Performance: UPJ series design emphasizes low impedance to improve transient response and reduce ESR-related losses in power circuits.
• High Ripple Capability: Defined ripple-current ratings at both low (120 Hz) and high (200 kHz) frequencies let designers size capacitors confidently for switching environments.
• Extended High-Temperature Life: 5000-hour endurance at 105°C supports long-term reliability in elevated-temperature applications.
• Compact Radial Can: φ16 × 15 mm package with standard 7.5 mm lead spacing fits common through-hole layouts while providing substantial capacitance.
• predictable leakage and loss characteristics: Specified leakage current and tanδ help ensure consistent behavior during biasing and in circuit simulations.
