UPJ1V122MHD6

The UPJ1V122MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series, delivered in a radial-lead can (φ16 × 25L) with 7.5 mm lead spacing. It is designed for general-purpose power applications and is specifically suited for switching power supplies where low impedance and sustained ripple handling are required.

Key value propositions include a 35 V rated voltage, 1,200 µF capacitance with ±20% tolerance, designed endurance at elevated temperature (5,000 hours at +105°C), and RoHS compliance for environmental compatibility.

Key Features

• Electrical performance — 1,200 µF capacitance at 35 V rated voltage with ±20% tolerance, offering bulk energy storage for power filtering and decoupling.
• Low impedance for switching supplies — Part of the UPJ series specified as “Low Impedance,” making it appropriate for switching power supply output and bulk filter stages.
• High ripple current capability — Rated low-frequency ripple current of 1,426.8 mA at 120 Hz and high-frequency ripple current of 1,740 mA at 200 kHz, supporting both line-frequency and high-frequency switching environments.
• Long endurance at elevated temperature — Rated life of 5,000 hours at +105°C (series specification), enabling reliable operation in thermally demanding installations.
• Leakage and loss characteristics — Specified leakage current of 1,260 µA (per product data) and tan δ of 0.12 measured at 20°C, 120 Hz, 35 V, supporting predictable performance in bias conditions.
• Robust operating range — Wide operating temperature range from −55°C to +105°C for use across varied ambient conditions.
• Radial can package — φ16 × 25 mm can with 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm) supplied in bulk/bag packing for through-hole assembly and prototyping.
• Regulatory compliance — RoHS compliant per product data.

Typical Applications

• Switching Power Supplies — Bulk output filtering and decoupling where low impedance and sustained ripple current handling improve voltage stability.
• Power Conversion Modules — Energy storage and smoothing in DC–DC converters and regulator modules that require high-temperature endurance.
• Industrial Controls — Bulk filtering and supply smoothing in industrial electronics subject to wide ambient temperature swings and continuous operation.
• Telecom and Infrastructure Power — Input/output filtering in communication power systems where high ripple current capacity and long life at elevated temperature are important.

Unique Advantages

• Designed for high-temperature endurance — 5,000 hours at +105°C supports long-term reliability in hot environments and continuous-duty applications.
• Measured ripple performance — Separate low-frequency and high-frequency ripple current ratings (1.427 A at 120 Hz and 1.74 A at 200 kHz) let designers size capacitors against real ripple conditions.
• Predictable leakage and dissipation — Specified leakage current (1,260 µA) and tan δ (0.12 at 35 V, 20°C, 120 Hz) provide verifiable electrical behavior for margin calculations.
• Compact radial form factor — φ16 × 25 mm can with radial leads and 7.5 mm pitch simplifies through-hole placement while delivering high capacitance in a small footprint.
• RoHS compliance — Conforms to environmental requirements for lead-free production and deployment.
