UHE1H121MPD

The UHE1H121MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UHE series, rated at 120 µF and 50 V with polarized construction. It targets general-purpose electronic designs that require compact, low-impedance energy storage with extended operating life.

Key value comes from its low impedance, long endurance (7,000 hours at 105°C), and compact φ8 × 15 mm can with 3.5 mm lead spacing—making it suitable for space-constrained board-level power applications that demand reliable ripple handling and temperature range coverage from −40°C to 105°C.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for polarized, DC-focused circuitry.
• Low Impedance — Specified impedance of 480 mΩ supports effective smoothing and decoupling in power circuits where low ESR is important.
• High Ripple Handling — Rated ripple current of 511 mA at 120 Hz and 730 mA at 10 kHz provides measurable RMS ripple capability for power-supply filtering and decoupling tasks.
• Long Endurance — 7,000 hours at 105°C (per product listing) supports long-term reliability under elevated operating temperature and bias.
• Loss Angle (tan δ) — tan δ of 0.10 at 120 Hz (50 V rating) for predictable dissipation characteristics under AC ripple conditions.
• Compact Radial Package — φ8 × 15 mm can with 3.5 mm lead spacing (radial lead mounting) and 0.5 mm lead diameter option, enabling easy through-hole assembly in compact layouts.
• Operating Range & Leakage — Operates from −40°C to 105°C with a specified leakage current around 60 µA (after rated voltage application), consistent with general-purpose electrolytic performance.
• Compliance — RoHS-compliant construction to meet environmental directive requirements.

Typical Applications

• General-purpose power filtering — Board-level smoothing and bulk energy storage in DC power supplies and converters where a polarized aluminum electrolytic is appropriate.
• Decoupling in embedded systems — Local bulk decoupling for microcontroller and peripheral power rails requiring compact, high-ripple capability components.
• Consumer and industrial electronics — General-purpose use across consumer and industrial circuits that need reliable electrolytic capacitance over a wide temperature range.

Unique Advantages

• Measurable ripple capacity: Rated ripple currents at 120 Hz and 10 kHz give designers clear limits for thermal and ripple budgeting in power circuits.
• Low impedance for effective smoothing: 480 mΩ impedance supports reduced voltage ripple and improved transient response compared to higher-impedance alternatives.
• Long rated life at elevated temperature: 7,000 hours at 105°C delivers predictable lifetime behavior for designs exposed to sustained thermal stress.
• Compact radial form factor: φ8 × 15 mm can and 3.5 mm lead spacing save board space while maintaining through-hole assembly simplicity.
• Consistent dissipation characteristics: tan δ of 0.10 at the rated condition provides a reliable reference for power-loss calculations.
• Regulatory compliance: RoHS conformity supports eco-conscious product requirements and supply-chain compliance.
