UPM1K680MPD

The UPM1K680MPD is an aluminum electrolytic capacitor from Nichicon’s UPM series, offering a 68 µF capacitance in a compact radial-lead can. Designed for demanding environments, it combines an 80 V rated voltage, low impedance and defined ripple-current capability to support power decoupling and smoothing on 12–48 V systems and other high-voltage rails.

With AEC-Q200 qualification, a -55 °C to +105 °C operating range and a 5000-hour endurance at 105 °C, the UPM1K680MPD targets applications that require reliable performance under thermal and electrical stress.

Key Features

• Capacitance & Voltage — 68 µF capacitance with an 80 V rated voltage and ±20% tolerance for predictable energy storage on higher-voltage rails.
• Low Loss / Low Impedance — tan δ = 0.08 (measured at 20 °C, 120 Hz) and impedance of 280 mΩ for reduced ESR-related heating and improved ripple handling.
• Ripple Current Capability — Rated ripple current of 181.1 mA at 120 Hz (low frequency) and 355 mA at 200 kHz (high frequency) to support filtering in switching and DC‑DC converter applications.
• Leakage and Reliability — Leakage current of 163.2 µA and a rated endurance of 5000 h at 105 °C, providing stable electrical characteristics over long-term use.
• Robust Temperature Range — Operates from -55 °C to +105 °C for use across wide thermal conditions.
• Automotive-Grade Qualification — AEC‑Q200 rated for use in automotive-qualified designs where that standard is required.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (lead spacing tolerance ±0.5 mm), available in bulk or bag packing for straightforward through-hole assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Automotive electronics: Suitable for control modules and power rails in automotive systems where AEC‑Q200 qualification, 80 V rating and high-temperature endurance are required.
• Power supply filtering: Use as output smoothing and bulk decoupling in DC‑DC converters and power rails thanks to 68 µF capacitance, low impedance and defined ripple-current ratings.
• In-vehicle infotainment and audio: Provides stable filtering and energy buffering for audio circuits and infotainment power domains operating across automotive temperature ranges.

Unique Advantages

• Voltage headroom for higher-voltage rails: 80 V rating supports applications beyond common low-voltage systems without series stacking.
• Long high-temperature life: 5000 hours at 105 °C endurance provides predictable long-term behavior in thermally stressed environments.
• Defined ripple performance: Separate low- and high-frequency ripple-current specifications (181.1 mA at 120 Hz, 355 mA at 200 kHz) let designers validate thermal and ripple handling across switching domains.
• Compact, through-hole form factor: φ10 × 20 mm radial can with 5 mm lead spacing simplifies retrofits and through-hole PCB layouts where board space is constrained.
• Automotive qualification and RoHS compliance: AEC‑Q200 rating and RoHS conformity support regulated production requirements and environmental compliance.
