UPT2P121MHD

The UPT2P121MHD is a polarized aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic equipment. It combines a compact φ12.5 × 35.5 mm package with high ripple-current capability and long-life endurance for demanding power applications.

Engineered for applications such as ballast circuits and other designs that require sustained ripple handling, the part offers a 220 V rated voltage, 120 µF capacitance, and wide operating temperature range from −40 °C to 105 °C.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a 220 V rated voltage and a tolerance of −20% to +20%, suitable for mid-voltage power circuits.
• High ripple-current capability: Rated ripple current of 490 mA at 120 Hz and 784 mA at 10 kHz, enabling effective AC ripple handling in ballast and power applications.
• Long endurance: 5000 hours rated life at 105 °C under DC bias plus rated ripple current, supporting extended service in elevated-temperature environments.
• Low-loss characteristics: tan δ (DF) up to 0.12 measured at 20 °C, 120 Hz, for predictable loss behavior in filter and smoothing applications.
• Leakage current: Specified leakage current of 1594 μA (measured after 2 minutes at 20 °C with rated voltage), enabling designers to budget for standby and leakage conditions.
• Form factor and mounting: Radial lead, polarized aluminum can with φ12.5 × 35.5 mm dimensions and 5.0 mm lead spacing (±0.5 mm), suited to through-hole PCB layouts.
• Operating range and compliance: Rated for −40 °C to 105 °C and RoHS-compliant for regulatory compatibility.
• Packaging options: Available in Bulk (No terminal forming) or Bag packing to support different assembly workflows.

Typical Applications

• Ballast circuits: Suited for ballast applications where high ripple current handling and long life are required.
• General-purpose power electronics: Used in equipment requiring 220 V electrolytic capacitance for smoothing, energy storage, or decoupling in through-hole designs.
• High-temperature environments: Components that must operate at up to 105 °C for extended periods, supported by the 5000 h endurance rating at 105 °C.

Unique Advantages

• High ripple-current capability: Measured ripple ratings at 120 Hz and 10 kHz allow designers to address both low- and high-frequency ripple in power circuits.
• Long-term reliability: 5000 hours endurance at 105 °C with defined limits on capacitance change, tan δ, and leakage current provides predictable aging behavior.
• Compact radial package: φ12.5 × 35.5 mm can and 5.0 mm lead spacing deliver a small footprint for through-hole layouts without sacrificing performance.
• Wide operating temperature: −40 °C to 105 °C rating supports use across a broad range of ambient conditions.
• Regulatory compliance: RoHS-compliant construction helps meet environmental and materials requirements.
• Flexible ordering: Bulk and bag packing options accommodate different inventory and assembly processes.
