UPM1J681MHD6

The UPM1J681MHD6 is an aluminum electrolytic capacitor from Nichicon’s UPM series designed for applications that require high reliability and low impedance. This radial‑lead, can‑style capacitor delivers 680 µF at 63 V with polarized construction and RoHS compliance.

Engineered for demanding environments, the part is AEC‑Q200 qualified and rated for operation from −55 °C to +105 °C with a demonstrated load life of 5000 hours at 105 °C, making it suitable for electronic systems where thermal endurance and stable filtering are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Low Impedance — Specified impedance of 35 mΩ to support lower ripple voltage and improved transient performance in power circuits.
• High Reliability — AEC‑Q200 qualified and long life rating: 5000 hours at 105 °C under rated load conditions.
• Temperature Range — Wide operating range from −55 °C to +105 °C for use across harsh thermal environments.
• Ripple Current Capability — Rated ripple current of 1.095 A at 120 Hz and 1.61 A at 200 kHz to support AC ripple and switching‑frequency stresses.
• Radial Can Package — 18 × 25 mm radial can with 7.5 mm lead spacing and polarized radial‑lead mounting for through‑hole assemblies.
• Leakage Current Specification — Series specification: after one minute at rated voltage and 20 °C, leakage current not more than 0.03 C V (µA), providing predictable stand‑by behavior.
• Compliance — RoHS compliant material and manufacturing.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and extended high‑temperature life make this capacitor suitable for in‑vehicle power modules and electronic control units where durability is required.
