UHW1H101MPD

The UHW1H101MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UHW series, optimized for high ripple current and high reliability in compact assemblies. Its 100 µF capacitance at 50 V, low impedance characteristics and long endurance make it suitable for general-purpose power filtering and decoupling in industrial, telecom and consumer electronics applications.

Designed for through-hole radial mounting, this part delivers measurable performance benefits—high-frequency ripple handling, low leakage and wide operating temperature—while occupying a φ8×11.5 mm can footprint with 3.5 mm lead spacing.

Key Features

• Capacitance and tolerance: 100 µF with ±20% tolerance at 120 Hz, 20°C, offering predictable bulk storage for power rails and smoothing applications.
• Rated voltage: 50 V DC rating suitable for medium-voltage power supplies and regulator stages.
• High ripple capability: Low-frequency ripple current 480 mA (120 Hz) and high-frequency ripple current 1.2 A (10 kHz), enabling reliable operation under dynamic load conditions.
• Low impedance and dissipation: Impedance of 360 mΩ and tanδ of 0.1 (20°C, 120 Hz), supporting stable decoupling at higher frequencies.
• Low leakage: Leakage current specified at 50 µA, minimizing quiescent loss and improving circuit stability.
• Wide temperature range and endurance: Rated for −40°C to +105°C with a life/endurance of 9,000 hours at 105°C for the 10–50 V range, supporting long-term reliability in elevated-temperature environments.
• Compact radial package: φ8×11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial-lead mounting for straightforward through-hole assembly and prototyping.
• RoHS compliant and production-ready: Lead-free, RoHS-compliant material set and listed as mass production status for supply continuity.

Typical Applications

• Power supply smoothing: Bulk smoothing and hold-up on medium-voltage rails where 100 µF capacitance and 50 V rating are required.
• DC-DC converter output filtering: High-frequency ripple capability and low impedance support stable output filtering for switching regulators and point-of-load stages.
• Embedded and industrial electronics: Decoupling and energy buffering in control modules and industrial boards operating across −40°C to +105°C.
• Telecom and consumer modules: Local energy storage and transient suppression in compact assemblies where radial-lead mounting is preferred.

Unique Advantages

• High ripple current handling: 1.2 A at 10 kHz enables robust performance in high-frequency converter outputs and pulsed-load conditions.
• Miniature footprint: φ8×11.5 mm can and 3.5 mm lead spacing reduce board area while keeping through-hole mounting simplicity.
• Long endurance at elevated temperature: 9,000 hours at 105°C (for 10–50 V ratings) supports extended service life in warm operating environments.
• Low leakage and low dissipation: 50 µA leakage and tanδ 0.1 at 120 Hz help minimize standby losses and thermal stress on the circuit.
• Predictable AC behavior: Specified impedance and frequency-rated ripple response aid in accurate power-stage design and simulation.
• Regulatory compliance: RoHS-compliant materials simplify regulatory handling and product acceptance for global markets.
