UPJ0J103MHD6

The UPJ0J103MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized electrolytic designed for bulk energy storage and smoothing in compact power designs.

Engineered for switching power supplies and general-purpose power applications, this part combines high capacitance (10,000 µF) at a low rated voltage (6.3 V) with a robust endurance profile to support continuous operation at elevated temperatures.

Key Features

• High Capacitance / Low Voltage — 10,000 µF nominal capacitance at a 6.3 V rating provides substantial bulk energy storage for low-voltage power rails.
• Low-impedance design for power — UPJ series is specified for low impedance and is suitable for switching power supplies, helping reduce ripple and maintain rail stability.
• Thermal endurance — Rated for operation from −55 °C to +105 °C with a specified life/endurance of 5,000 hours at 105 °C, enabling long-term reliability in continuous-duty environments.
• Ripple current capability — Supports 2.016 A at 120 Hz (low frequency) and 2.24 A at 200 kHz (high frequency), suitable for PSU ripple and decoupling across switching frequencies.
• Electrical characteristics — Capacitance tolerance ±20%, measured tanδ (DF) 0.4 at 20 °C / 120 Hz, and a measured leakage current of 1,890 µA as specified for this part.
• Compact radial-can package — Case diameter φ18 mm with length 30.5 mm and 7.5 mm lead spacing (±0.5 mm) in a radial lead form factor for through-hole mounting and reliable mechanical retention.
• Packaging and compliance — Supplied in bulk/bag packing and RoHS compliant for restrictive-substances requirements.

Typical Applications

• Switching power supplies — Bulk smoothing and output filtering to reduce ripple and support load transients in compact SMPS designs.
• DC-DC converters — Energy storage for low-voltage converters where high capacitance and ripple handling are required.
• Industrial and communications power modules — Bulk reservoir and decoupling in control modules and telecom equipment operating across a wide temperature range.

Unique Advantages

• High bulk capacitance at low voltage — 10,000 µF at 6.3 V allows designers to reduce component count for bulk storage on low-voltage rails.
• Designed for continuous high-temperature operation — 5,000 hours endurance at 105 °C supports long-term stability in thermally demanding systems.
• Wide operating temperature range — −55 °C to +105 °C provides design margin for industrial and outdoor equipment subject to temperature extremes.
• Strong ripple handling across frequencies — Specified ripple current at both 120 Hz and 200 kHz addresses performance across transformer- and switching-based supplies.
• Through-hole radial form factor — φ18 × 30.5 mm can and 7.5 mm lead spacing simplify assembly and mechanical mounting for robust PCB retention.
• RoHS compliant — Meets regulatory requirements for lead-free manufacturing and restricted substances.
