UPS0J331MED

The UPS0J331MED from Nichicon is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a radial‑lead, polarized can type that combines a compact footprint with-rated capacitance and ripple handling tailored for space‑constrained power designs.

Key value propositions include a wide operating temperature range (−55°C to +105°C), RoHS compliance, and a 2000‑hour endurance rating at 105°C—providing reliable decoupling and smoothing in demanding thermal environments.

Key Features

• Rated Capacitance & Voltage — 330 µF capacitance at a 6.3 V rating, suitable for decoupling and bulk energy storage in low-voltage power rails.
• Miniature Radial Package — Compact dimensions (L: 1.1 × D: 0.63 cm) with 2.5 mm lead spacing in a radial, can-style package for robust through-hole mounting.
• Low Impedance & Ripple Capability — Engineered for low impedance; rated ripple current of 177.5 mA at 120 Hz and 250 mA at 10 kHz supports switching supply ripple demands.
• Wide Temperature Range — Specified for operation from −55°C to +105°C to maintain performance across broad thermal conditions.
• Endurance — 2000 hours at 105°C specified lifetime for sustained high-temperature operation.
• Loss & Leakage Characteristics — Low-loss behavior with tan δ (max.) of 0.24 at 6.3 V (measured at 120 Hz, 20°C) and leakage current specified as ≤ 0.03CV (µA) after 1 minute at 20°C.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Switching Power Supplies — Local bulk and output smoothing in compact switching regulators where low impedance and rated ripple current are required.
• Power Supply Decoupling — Bulk decoupling on low-voltage rails in space-limited assemblies to stabilize voltage during transient loads.
• General Purpose Electronics — Through-hole mounting for robust connections in consumer and industrial PCBs requiring durable electrolytic capacitance.

Unique Advantages

• Compact footprint: Small can size (1.1 × 0.63 cm) and 2.5 mm lead spacing reduce board area without sacrificing capacitance.
• Wide thermal tolerance: −55°C to +105°C rating enables consistent performance across harsh temperature profiles.
• Designed for switching environments: Low impedance and defined ripple current ratings at both 120 Hz and 10 kHz make the part a fit for switched-mode power stages.
• Measured electrical stability: Specified tan δ and leakage current limits provide predictable loss and leakage behavior for design validation.
• Manufacturing and regulatory readiness: Radial-lead can package for reliable through-hole assembly and RoHS compliance for regulatory conformity.
• Rated endurance: 2000 hours at 105°C supports longevity in thermally stressed installations.
