UPZ2G121MHD

The UPZ2G121MHD is a miniature-sized, high-voltage aluminum electrolytic capacitor with radial leads, designed for general-purpose use in high-voltage circuits. It offers 120 µF capacitance at a 400 V rating in a compact radial-can package with 7.5 mm lead spacing.

Engineered for elevated-temperature operation, the device supports an operating range of –40°C to +105°C and a rated lifetime of 2000 hours at 105°C under specified endurance conditions.

Key Features

• Capacitance & Voltage: 120 µF rated capacitance at 400 V, for energy storage and filtering in high-voltage circuits.
• Compact Radial Can Package: Radial lead mounting with 7.5 mm lead spacing and a physical size of L: 3.55 x D: 1.6 cm, enabling easy through-hole integration.
• Wide Temperature Range: Specified for operation from –40°C to +105°C, suitable for applications requiring elevated-temperature endurance.
• Endurance Verified: Meets endurance criteria after 2000 hours at 105°C with DC bias plus rated ripple current: capacitance change within ±20%, tan δ up to 200% of initial spec, and leakage current not exceeding initial value.
• Ripple Current Performance: Rated ripple currents include 670 mA at 120 Hz and 1.005 A at 10 kHz, with frequency coefficients provided in the UPZ series data for different frequency ranges.
• Leakage Current Specification: Leakage after 1 minute at 20°C is defined by the formula 0.04CV + 100 (µA), providing a clear expectation for insulation performance.
• Dielectric Loss (tan δ): For the 400 V rating the series specifies a maximum tan δ of 0.15 (measured at 120 Hz, 20°C), supporting predictable AC characteristics.

Typical Applications

• General-Purpose High-Voltage Circuits: Suitable where a polarized 120 µF / 400 V radial-lead capacitor is required for energy storage or smoothing.
• Power Supply Filtering: Use in power supply sections that require high-voltage capacitance and moderate ripple handling at frequencies including 120 Hz and higher.
• Industrial and Test Equipment: Compact radial-can format and elevated-temperature endurance make it appropriate for general-purpose industrial electronics and laboratory equipment.

Unique Advantages

• High Voltage in a Small Footprint: 400 V rating combined with a compact L: 3.55 x D: 1.6 cm package delivers high-voltage capacitance where board space is limited.
• Through-Hole Simplicity: Radial lead mounting and 7.5 mm lead spacing simplify assembly and replacement in through-hole designs.
• Temperature-Endurance Assurance: Rated for –40°C to +105°C with a documented 2000-hour endurance at 105°C, providing predictable life under elevated-temperature stress.
• Defined Ripple and Loss Characteristics: Published ripple current figures and tan δ limits for the 400 V rating enable accurate thermal and AC performance planning.
• Clear Leakage Current Metric: Leakage current defined by 0.04CV + 100 (µA) after 1 minute at 20°C simplifies acceptance criteria and quality checks.
