UHW1A122MPD

The UHW1A122MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHW series. It is a radial-lead, polarized capacitor rated at 1200 µF and 10 V, optimized for compact designs that require elevated ripple-current capability and wide operating temperature range.

Designed for general-purpose electronics, this part delivers a combination of low impedance (90 mΩ), measurable low-frequency and high-frequency ripple performance, and a 10 000‑hour endurance at 105 °C for predictable long-term operation.

Key Features

• Electrical performance: 1200 µF capacitance with ±20% tolerance and a measured impedance of 90 mΩ, providing stable bulk capacitance for power circuits.
• Loss characteristics: tanδ (DF) = 0.18 measured at 20 °C, 120 Hz, with datasheet guidance on loss increases for capacitances >1000 µF.
• High ripple-current capability: Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 2.0 A (10 kHz), suitable where substantial ripple handling is required.
• Reliability and endurance: Rated life 10 000 hours at 105 °C under specified conditions, supporting extended operation in elevated-temperature environments.
• Wide temperature range: Operating from −40 °C to +105 °C to cover a broad range of environmental conditions.
• Package and mounting: Radial lead, can-style package with dimensions φ10 × 16L and lead spacing 5.0 mm (tolerance ±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Leakage current: Specified leakage current of 120 µA for predictable standby losses and charge-holding behavior.
• RoHS compliant: Meets RoHS requirements as indicated for the UHW series.

Typical Applications

• General-purpose circuits: Suitable for compact electronic modules that require bulk capacitance at 10 V with a radial-lead, through-hole mounting style.
• High-ripple environments: Appropriate where elevated ripple currents occur, leveraging the 1.2 A (120 Hz) and 2.0 A (10 kHz) ripple ratings.
• Temperature-challenged designs: Use in designs that must operate across −40 °C to +105 °C with a 10 000‑hour endurance at the upper temperature limit.

Unique Advantages

• Compact, high-capacitance option: 1200 µF in a φ10 × 16L package conserves board space while providing significant bulk energy storage.
• High ripple-handling capability: Clearly specified low- and high-frequency ripple currents enable reliable performance in power-dense circuits.
• Predictable endurance: 10 000 hours at 105 °C gives designers a measurable reliability baseline for thermal-stress planning.
• Low impedance and controlled loss: 90 mΩ impedance and documented tanδ support designs that need stable AC performance.
• Through-hole convenience: Radial-lead, can-style package allows straightforward placement in through-hole assemblies and simple mechanical mounting.
• Regulatory compliance: RoHS compliance supports environmentally constrained product designs.
