UHW1C122MPD6

The UHW1C122MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized capacitor with 1200 µF capacitance and a 16 V rating, designed for general-purpose electronic applications that require compact size, high ripple handling and long endurance.

Key value comes from a combination of low impedance, high ripple current capability at both low and high frequencies, and a measured endurance of 10,000 hours at 105°C—making it suitable for compact power circuits operating across a wide temperature range.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable bulk energy storage.
• Miniature Radial Can — Compact φ10 × 16 mm can with 5.0 mm lead spacing (±0.5 mm) in a radial-lead package for through-hole mounting and tight board layouts.
• Low Impedance — Rated impedance of 90 mΩ supports efficient decoupling and energy delivery in power circuits.
• High Ripple Current — Low-frequency ripple current of 1.2 A at 120 Hz and high-frequency ripple current of 2.0 A at 10 kHz to handle both bulk and high-frequency switching ripple.
• Loss Characteristics — tan δ (DF) of 0.15 measured at 20°C, 120 Hz, and leakage current specified at 192 µA for predictable dissipation and standby behavior.
• Wide Operating Temperature — Rated for −40°C to +105°C to accommodate a broad set of environmental conditions.
• Long Endurance — Life/endurance specified at 10,000 hours at 105°C for designs requiring sustained performance under elevated temperature.
• RoHS Compliant & Packaging Options — RoHS-compliant construction with bulk (no terminal forming) or bag packing options for production handling.

Typical Applications

• General-purpose power filtering — Bulk capacitance and low impedance let this capacitor smooth supply rails and reduce low-frequency ripple in compact power supplies.
• Switching regulator output — High-frequency ripple rating and low DF help manage switching ripple at higher frequencies in regulator outputs.
• Decoupling and energy storage — Small can diameter and high capacitance provide local energy buffering in space-constrained boards.

Unique Advantages

• Compact high-capacitance solution: 1200 µF in a φ10 × 16 mm package reduces board area while delivering substantial energy storage.
• Dual-frequency ripple capability: Specified ripple currents at 120 Hz and 10 kHz let designers manage both line-frequency and switching-frequency stress.
• Predictable thermal endurance: 10,000-hour life at 105°C provides a clear reliability target for thermal design and lifetime budgeting.
• Low impedance and controlled dissipation: 90 mΩ impedance and tan δ = 0.15 support efficient filtering with known power loss characteristics.
• Through-hole mounting convenience: Radial-lead package and standard 5 mm lead spacing simplify prototyping and serviceability.
• Regulatory compliance: RoHS status supports designs targeting environmental compliance.
