UHW1A821MPD

The UHW1A821MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. This radial-lead, polarized capacitor delivers 820 µF capacitance at a 10 V rating in a compact φ8 × 15 mm can.

Designed for general-purpose applications, the UHW1A821MPD pairs low impedance and high ripple-current capability with a long endurance of 10,000 hours at 105°C, making it suitable for compact power filtering and decoupling needs in electronic designs.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20%.
• High ripple-current capability — Rated low-frequency ripple current of 960 mA at 120 Hz and high-frequency ripple current of 1.6 A at 10 kHz, enabling effective smoothing at both low and high frequencies.
• Low loss and impedance — Specified tanδ of 0.18 (20°C, 120 Hz) and impedance of 170 mΩ for improved performance across frequency ranges.
• Long endurance — Endurance rated at 10,000 hours at 105°C under rated DC bias plus ripple current, with controlled limits on capacitance change, tanδ and leakage current after the endurance test.
• Compact radial package — φ8 × 15 mm can with radial leads (lead spacing 3.5 mm, lead spacing tolerance ±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Leakage current — Specified leakage current of 82 µA (product data), supporting stable long-term operation.
• Regulatory — RoHS-compliant construction.
• Packaging options — Available in bulk (no terminal forming) or bag packing for flexible handling and assembly workflows.

Typical Applications

• General Purpose Electronics — Provides 820 µF at 10 V for general-purpose power storage and decoupling in compact electronic assemblies.
• Power Filtering — Supports up to 960 mA ripple at 120 Hz and 1.6 A at 10 kHz for smoothing and ripple suppression in power supply rails.
• Embedded and Industrial Systems — Compact can size and long 10,000-hour endurance at 105°C suit designs requiring robust, long-life bulk capacitance.
• Through-Hole PCB Designs — Radial-lead package with 3.5 mm lead spacing simplifies placement and solder-through-hole mounting.

Unique Advantages

• High ripple capability in a small footprint: Delivers 1.6 A at high frequency (10 kHz) and 960 mA at 120 Hz from a φ8 × 15 mm can, enabling greater ripple handling without increasing board area.
• Long-term thermal endurance: Rated for 10,000 hours at 105°C, supporting reliable operation in elevated-temperature environments.
• Low impedance and controlled loss: 170 mΩ impedance and tanδ 0.18 (20°C, 120 Hz) provide stable AC performance for decoupling and filtering tasks.
• Clear, manufacturer-backed specification: Nichicon UHW-series design and documented endurance/leakage limits make performance verifiable against datasheet parameters.
• RoHS compliance: Meets RoHS requirements for environmentally restricted substances.
• Flexible packaging for production: Offered in bulk or bag packing to match assembly and inventory workflows.
