UPW1A181MED

The UPW1A181MED is a miniature, polarized aluminum electrolytic capacitor in Nichicon's UPW series, designed for high reliability applications. It is a radial-lead, can-style component offering low impedance in a compact footprint.

With a rated capacitance of 180 μF at 10 V, an operating temperature range of −55°C to 105°C, and AEC-Q200 qualification, this part is intended for demanding power-filtering and decoupling roles where compact size, thermal robustness, and established reliability are required.

Key Features

• Capacitance & Voltage: 180 μF nominal capacitance with a 10 V rated voltage, suitable for mid-level filtering and energy storage in compact power circuits.
• Miniature radial-can package: Radial lead, can-style package with lead spacing of 2.5 mm and overall size L: 1.1 × D: 0.63 cm, enabling space-efficient through-hole designs.
• High reliability (AEC-Q200): AEC-Q200 rating indicates qualification for applications requiring industry-recognized reliability standards.
• Wide temperature range: Specified for −55°C to 105°C operation, supporting designs exposed to broad thermal environments.
• Endurance: Rated for 2000 hours at 105°C, providing predictable long-term performance under elevated-temperature conditions.
• Ripple current capability: Rated ripple currents include 188.5 mA at 120 Hz and 290 mA at 10 kHz, supporting smoothing and decoupling in switching supplies across frequency ranges.
• Polarized construction: Designed as a polarized electrolytic capacitor for correct DC polarity applications; capacitance tolerance is −20% to +20%.

Typical Applications

• Switching power supplies: Low-impedance, miniature form factor makes the UPW1A181MED suitable for output filtering and decoupling in compact switching regulators.
• Automotive electronic modules: AEC-Q200 qualification and wide operating temperature range suit power filtering in automotive control units and infotainment systems.
• DC–DC converters and power-conditioning: Ripple current ratings at both low and high frequencies support stable operation in DC–DC stages and power-conditioning circuits.
• Compact industrial electronics: Small radial-can package and robust endurance at elevated temperature make it appropriate for space-constrained industrial control boards.

Unique Advantages

• Space-efficient performance: Compact L × D dimensions (1.1 × 0.63 cm) and radial-lead packaging reduce board area for through-hole power designs.
• Designed for elevated-temperature endurance: 2000 hours at 105°C gives designers quantifiable life expectations under high-temperature stress.
• Frequency-aware ripple capability: Documented ripple current values at 120 Hz and 10 kHz enable confident selection for both line-frequency smoothing and high-frequency switching applications.
• Automotive-grade qualification: AEC-Q200 rating supports use in regulated automotive environments requiring standardized reliability validation.
• Robust operating range: −55°C to 105°C operation accommodates a wide range of ambient and system temperatures without speculation beyond published limits.
