UPT2D681MRD6

The UPT2D681MRD6 from Nichicon is a miniature aluminum electrolytic capacitor in the UPT series designed for general-purpose power applications that demand high ripple current and long operational life. It is a polarized, radial-lead can rated at 200 V with a capacitance of 680 µF, offering a compact option for compact power filtering and energy-storage needs.

Engineered for continuous operation up to 105°C and compliant with RoHS, this component is suitable for applications such as ballast circuits and other power-electronics designs that require sustained ripple handling and temperature endurance.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, providing substantial energy storage for smoothing and decoupling tasks.
• High ripple-current capability — Rated ripple current of 1.5 A at 120 Hz and 2.4 A at 10 kHz, supporting demanding AC ripple conditions in power circuits.
• Long-life specification — Designed for 5000 hours of operation at 105°C under rated DC bias plus ripple current, with specified endurance limits for capacitance, tan δ and leakage current.
• Wide operating temperature — Specified for −40°C to +105°C operation to accommodate a broad range of thermal environments.
• Radial lead, compact package — Radial, can-style package with radial lead mounting and 1.25 cm lead spacing for through-hole PCB assembly; physical size approximately L: 4 × D: 2.5 cm.
• Regulatory — Compliant with RoHS (2011/65/EU, (EU)2015/863).
• Polarized construction — Polarized electrolytic design for DC power applications requiring correct polarity handling.

Typical Applications

• Ballast and lighting power supplies — Suited for ballast application where high ripple current capability and thermal endurance are required.
• Power-supply filtering — Bulk smoothing and ripple suppression in general-purpose DC power supplies and converters.
• Industrial electronics — Energy storage and decoupling in compact industrial control modules operating up to 105°C.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors with confidence for specific AC ripple environments.
• Proven long-life rating: 5000 hours at 105°C under rated conditions provides a predictable lifetime baseline for thermal-stressed designs.
• Compact footprint: Miniature radial can package (approx. 4 × 2.5 cm) lets you retain capacitance while saving board area compared with larger form factors.
• Wide temperature range: −40°C to +105°C spec supports deployment across varied environmental conditions.
• Regulatory compliance: RoHS conformity supports designs that must meet current environmental directives.
